Jack Wolfskin has been an industry leader since it’s inception in 1981, and the world renowned brand shows no signs of slowing down.

Over the years their ranges have expanded and their list of technologies has grown but one thing remains the same; their dedication to providing their customers with the best gear for all weathers and adventures. True to their original core values; Jack Wolfskin aim to provide the best gear possible to ensure that everyone can get outside and enjoy what mother nature has to offer.

Here at Tog-Blog we decided that a brand with such a formidable reputation was well overdue one of our comprehensive technology guides. The North Face and Merrell already have their own dedicated guides on our blog, so finally today we bring to you The Jack Wolfskin Technology Guide.


ACS technology involves the curvature of the pack sack and a large mesh surface to create a ventilation space between your back and the backpack. This allows warm air to escape for superior ventilation, efficient heat transport and a comfortable fit.

ACS Tight

ACS Tight features two soft back pads that sit either side of the spine to form a central ventilation panel as well as a reinforcement plate that evenly distributes the weight of the pack and protects from heavy loads. This ensures excellent ventilation, superior freedom of movement and a close contact pressure free fit.


Jack Wolfskin regularly use down fill to insulate their products for cold weather performance. It offers a great warmth to weight ratio, heat retention, compressibility, loftiness and a small pack size; making it ideal for garments and sleeping bags intended for use in cold dry weather (unless treated with water repellent technology).


DownFiber technology boasts the insulating warmth of down with the moisture resistance of synthetic fibres for versatile outdoor performance. This innovative insulation is constructed from 70% down and 30% Fibrecloud, and the loft can be customised by changing the type of down used. The 70% down is also treated to be water repellent with a PFC treatment for superior insulation in wet and damp conditions. DownFiber dries fast, has an excellent warmth to weight ratio, a small pack size, high heat retention, is moisture resistant and durable.

No matter where you go from your morning commute to a once in a lifetime adventure holiday you’re bound to see someone sporting a piece of their premium quality gear.

With all of these achievements and innovations it isn’t easy to keep up, and here at we often find ourselves struggling to remember which technology does what. It’s understandable and with an industry leading brand like North Face no one can blame us. They have a piece of technology, a new fabric or a new construction for every garment and adventure.

So, with it being the New Year and all we decided that it was time to make some resolutions. We’re determined to keep on top of tech this year and we decided that the best way to do that was to create a definitive guide of all North Face technologies. So if you’re like us and you can’t keep up with the full steam ahead pace of this game-changing brand keep reading and bookmark this page for future reference!


FuseForm is one of the North Face’s latest and greatest innovations. It offers a seamless, lightweight construction by using advanced manufacturing techniques to weave two material properties into one single fabric. This eliminates the extra thread and tape of traditional seams which means a lighter weight, lower bulk, stronger and more durable construction with a clean aesthetic.


Developed in partnership with Primaloft; Thermoball is the new synthetic insulation alternative to down. Thermoball works with small, round synethetic fibre that clusters closely together to trap heat within small air pockets. This ensures excellent heat retention, compressibility, loft and low weight like traditional down insulation but boasts the added benefit of wet weather performance. Unlike traditional down insulation Thermoball still offers exceptional insulation when wet making it perfect for alpine adventures.


FlashDry is an innovative proprietary fabric created to offer superior moisture management and temperature regulation. FlashDry is ideal for creating active outdoor use garments and offers drier, more comfortable performance in unreliable weather conditions. FlashDry fabric works by accelerating the evaporation process and is permanently embedded in the yarn so that performance doesn’t diminish within a few washes.

There are actually three different types of FlashDry, each suited to creating a different garment.

FlashDry Fibre Technology works by permanently embedding a microporous additive in at the fibre level to increase the surface area. This aids cooling, drying and makes it ideal for base layers.

FlashDry Thermal Technology works by permanently embedding a microporous additive into synthetic fibres which ensures an excellent warmth-to-weight ratio. This allows for excellent warmth with minimal bulk and is ideal for fleeces.

FlashDry Laminate Technology features a three dimensional, microporous layer of additives printed onto a hydrophilic membrane surface. This allows liquid and evapourative moisture to be transferred away from the body ensuring a 100 percent waterproof exterior and superior next to skin comfort. It is durable and ideal for use in wet and alpine environments.

Goose Down Fill

The North Face only use premium quality goose down fill in their down products. Tested for loftiness, moisture resistance and ability to regain loft after compression you can be sure that you are getting the best down. Several different fill powers of down are used in their products depending on the garment and the activity that is designed for. All goose down fills boast superior comfort and warmth, light weight and unrivalled quality.

900 fill goose down is the highest quality commercially available down. It is generally considered the highest standard of insulation with an unrivalled warmth to weight ratio, superior compressibility, ultralight weight and excellent comfort. It is generally used in North Face’s Summit Series.

800 fill goose down is the next fill often used in North Face’s products. It offers exceptional warmth thanks to it’s high cluster to feather ratio and boasts increased loft as well as compressibility.

700 fill goose down offers a good warmth to weight ratio, is lightweight and is great for insulating across a range of different temperatures. 700 fill is often chosen for it’s versatility and is ideal when you need to be prepared for a range of climates.

600 fill down is most often the lowest fill down that is used in the North Face’s products, although they have been known to use 550 and 500 in some of their gloves and smaller products. It is warm, lightweight, durable and offers ideal performance for general day to day or outdoor use.


Gore-Tex is a waterproof, windproof and breathable membrane technology that allows the user to enjoy maximised protection and comfort without compromising on performance. The North Face generally uses two different kinds of Gore-Tex membrane technology.

Gore-Tex Pro technology is designed to be rugged for extreme use. Gore-Tex Pro garments are durable, waterproof, windproof and breathable and are designed for high impact action packed adventures. It boasts a three layer construction with a membrane that is bonded to a durable outer material and a robust inner lining. This ensures no movement between the layers and maximises durability.

Gore-Tex Active technology boasts superior breathability ideal for highly aerobic activities. Ideal for short bursts of active use such as a day hiking in the hills is boasts fine laminate denier performance textiles and a three layer construction. Proprietary lamination technology integrates the backer textile directly into the Gore-Tex membrane; therefore allowing enhanced breathability and comfort.


Hyvent is a waterproof and breathable technology that uses a polyurethane coating consisting of a tri component to deliver superior waterproofing, moisture permeability and durability. The North Face uses several different specialised types of Hyvent depending on the garment and intended use. All Hyvent technologies are waterproof, breathable and offer excellent protection in rain and snow.

Hyvent Alpha is most commonly used in the Summit Series collection. It is rugged, waterproof and uses a microporous hydrophobic lamination technology to maintain durability and waterproofing in extreme conditions. Hyvent Alpha garments are designed for heavy duty alpine performance.

Hyvent 2 Layer, as the name suggests, boasts a two layer construction that allows it to stay waterproof and breathable and severe conditions. Ideal for exploration it boasts a durable woven outer layer to repel wet weather and an inner layer with a PU coating and micro-pores to channel water vapour out of the garment. This water vapour redirecting technology is ideal for climbing and skiing.

Hyvent 3 Layer is a three layer construction technology and like it’s counterparts it is both breathable and waterproof. It features a durable woven outer layer that repels wet weather, a PU coated mid layer with micro pores to redirect water vapour and a design that is geared towards superior moisture management. This technology excels in alpine environments.

Hyvent DT features the same principle as Hyvent 3 Layer but with a reduced thickness of the third layer. This makes it exceptionally lightweight and packable whilst still offering excellent moisture management. This technology is ideal for multi-day adventures and is sometimes referred to as Hyvent 2.5 Layer.

Hyvent DT EC is created using naturally derived materials and uses 50 percent less synthetic components compared to other conventional fabric membranes. It maintains excellent waterproof and breathable performance in cool to cold conditions, but with the added bonus of a reduced environmental impact. This technology is ideal for backpacking.


PrimaLoft sport offers high performance insulation by combining ultra-fine and multi-diameter fibres to deliver specific performance characteristics. The ultra-fine fibres are specifically treated to aid water resistance, and the multi-diameter fibres help to build loft. There are three main types of PrimaLoft insulation that the North Face uses.

PrimaLoft One is arguably their leading microfibre insulation. It is created by treating ultra-fine fibres in a patented process and combining them into an insulating core for lightweight, soft and water resistant performance. PrimaLoft one is 14 percent warmer when dry and 24 percent warmer when we than other competitive insulation.

The North Face Ethical Down Update

You know the post we put out a week or so ago about sustainable down sourcing by Webtogs’ brands? Well I have a very positive update from The North Face regarding the development of their ‘Responsible Down Standard’ – namely, after two years in development, it is complete! You can read the full update from TNF themselves here, in their official release.

Now that pre-pilot audits on The North Face’s existing down suppliers have been completed, they are now in a position to roll out the finalised RDS (Responsible Down Standard) across their entire global supply chain. All down in The North Face down products by Autumn/Winter 2015 will comply with the RDS (allowing for time to conduct full audits, and for geese to reach maturity), and what’s more the enforcement of the standard is to be handed over to third-party, non-profit organisation Textile Exchange. They are committed to minimising the harmful effects of the global textile industry, and encouraging the positive ones, for the benefit of textile workers, animals, and all of us.

Webtogs Road-Trip to the Brit-Brand Trio & Marmot!

Aptly-named snack of the week. Great value too.
Aptly-named snack of the week

I should probably start out by explaining that when I say ‘Brit brand trio’, I’m referring to Rab, Mountain Equipment and Montane. These three brands are the standard-bearers for the UK outdoor industry, and between them they account for over half of the products ranged on at any given time. It was these brands, along with another of our suppliers; US brand Marmot, that Webtogs MD Keith and I set out to visit last Sunday on a 5-day buying road-trip. I can report that it was epic thanks to the exciting new products on show… and the added bonus of getting to take the bike out on some awesome trails in the Lakes (Altura Trail, Whinlatter & The North Face Trail, Grizedale) and Peak District!

Take Note World: Rab is Awesome

Last weekend whilst discussing work with my friend Alex, I was surprised to hear that he had never heard of the brand Rab. This was very surprising to me, because of the 50+ brands we sell at Webtogs, Rab ranks second only to The North Face in terms of sales – and even then it’s a close-run thing. It’s also very much the ‘it’ brand in the market at the moment, with a rapidly expanding fan-base and amazing sell-through, not to mention the fact that it’s been around as a flag bearer of the British outdoor kit industry since the 1980s.

What’s the best Insulation for cold weather?

What's the best insulation for cold weather?

As the weather gets colder, we are often asked what the best way to keep warm is, so after a bit of feedback on our Facebook page, here’s our guide to the different sorts of insulation out there for your mid & outer layers.

Sadly there is no “wonder insulation” that’s going to keep you warm, be breathable, pack down small, deal with snow & rain, save you from an avalanche and make you a cup of tea in the morning. We think it’s a horses for courses approach for your insulating layers, get the right thing for the right situation. So without further ado, let’s take a look at the three main types you can choose.


DOWN: Natures warmth, the fluffy stuff underneath a birds feathers.

SYNTHETIC: Synthetic fibres woven together to trap air and keep you toasty.

FLEECE: Another synthetic option that’s a fabric in it’s own right (rather than fibres that you put in to a jacket)

Now we’ve sorted out what we’re going to take a look at, let’s dive in and take a quick look at the good and the bad of our contestants.


Down Jackets & Vests

Down Jackets & VestsGOOD STUFF: The highest Warmth to Weight ratio of all the options here, goose down is fabulous stuff for trapping air and keeping you warm. It feels seriously sexy to wear, is incredibly lightweight, and packs down smaller than any of the other options here. Great to pull on after a hard day on the mountain, or when wandering out and about.

NOT SO GOOD STUFF: If down gets wet it doesn’t work, so it’s really important to keep it dry at all times. We reckon it works best in cold, snowy climates, or where you bring along a waterproof to stop it getting damp. A little more expensive than some of the other options and maybe too hot if you are doing energetic activities.

STUFF TO LOOK OUT FOR. Without boring you, down is graded according to fill power, e.g how much space a load of down takes up by weight, the range goes from 450 through to 900 odd, the higher the number, the warmer (and lighter) the down.

Synthetic Jackets

Synthetic Insulated JacketsGOOD STUFF: Synthetic Insulation is best known with examples such as Primaloft or own brand examples like The North Face’s Heatseeker. Water resistant, it retains a lot of it’s insulating properties even if soaked through, and it’s less expensive than down.

NOT SO GOOD STUFF: It has a greater bulk and weight than down and is less breathable.

STUFF TO LOOK OUT FOR: A favourite with climbers and those who use their insulation out and about. It works best in wet environments, which apparently we get rather a lot of here in the UK!

Fleece Jackets & Vests

Fleece jackets and vestsGOOD STUFF: Fleece has amazing breathability, and is an awesome choice if you are doing blood pumping activities in the cold. Fleece is water resistant, drys quickly and is great value for money.

NOT SO GOOD STUFF: Fleece is not usually windproof so unless you have some sort of shell layer over the top, the cold wind is going to go whistling through you and take that trapped air and heat away. Relatively heavy and bulky compared to some of the other options.

STUFF TO LOOK OUT FOR: The best known fleece fabric is Polartec, but there are many other own brand examples out there too. Fleece comes in a variety of different flavours e.g. lightweight, midweight & heavyweight.

So there you have our quick guide to insulation. We reckon you need to balance your budget, activity and whether you are wearing it during the day or at journeys end. If you are a backpacker for example, weight is perhaps the most important thing to consider. If you need to get warm at camp at the end of the day, we would suggest grabbing a down vest or jacket. Down is also great if you are just taking the dog out for a quick walk. Climbing and need a belay piece? It has to be Synthetic. Running or walking out in the cold? Grab a fleece to wear underneath your windshirt or waterproof.

What’s your favourite insulation piece when the cold come round?
