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.

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!

All new Adidas winter 2011 collection – including Terrex Active Shell

We recently had Jon down from Adidas to guide us through the new Autumn Winter collection 2011. We were rather excited to have him down as this will be the first time we will stock both the Adidas clothing range as well as their footwear. You can tell just how excited I was from this video below!

There were quite a few pieces that really stood out, first the Terrex Primaloft Parka.

Terrex Primaloft Parka

Terrex Primaloft Parka shoulder

Terrex Primaloft Parka hood

It looks like a great belay jacket with some about town practicality. I was particularly impressed with the adjustability of the hood. Coming in at roughly 900g it’s a solid piece and is backed up with Climaproof storm, Adidas’ own waterproof breathable fabric.

Terrex Hybrid pant

Next up was the Terrex Hybrid pant. This is a fully featured mountain trouser with a great combo of Gore Windstoppper for most of the trouser, and Climaproof for the high wear areas. You have built in gaiters, and some nice touches with rubberised elastic bands on the inside of the trousers to help grip & keep the trousers up. At £130 this is great value for such a high spec pair of pants.

Terrex Active Shell Jacket

Terrex Active Shell detail

This was the one that really got my attention. There has been a great deal of noise recently in respect of new technologies when it comes to waterproof, breathable fabrics. Mountain Hardwear have released their Dry-Q for later this year, Polartec have their Neo Shell and Goretex have released Active Shell. All are competing to be the lightest most breathable waterproof fabric out there.

What was immediately different for me was the feel of the Active Shell jacket. I was expecting a light jacket, but the feel was also subtly different to a hard shell being a little more flexible and not quite as noisy when moving. It also felt great next to my skin. Aside from the feel of the fabric, I really liked the permanent built in venting, the helmet compatible hood and the overall weight at just shy of 370g. I am really looking forward to this coming in so will keep you updated as soon as we get to test it in anger on the hill.

Womens Fleece pink

Womens Fleece blue

We also had a couple of women’s fleeces in some vibrant colours, Lucy tried them on and the cut got the thumbs up.

Terrex Windstopper Soft Shell Jacket

Finally we had the Terrex Windstopper soft shell jacket, featuring some cavernous pit zips and a great athletic cut, coming in just under 590g in weight. It looks like a good value shell.

All in all a collection that has got us wishing for snow, short days and long nights again – roll on Winter 2011!
