POWER WOOL: SOPHISTICATED SOLUTIONS

power wool is soon to have it’s big release for fall-winter, so it’s a good time to get some real-world beta out there along side the endless press releases and showroom fondling from the trade show circuit. having used the stuff over almost a year and taken it from baking granite walls to nasty tibetan snow storms and lots of variety of trips between, a decent perspective on the stuff exists.

high exertion, bleaching sun, cold conditions: Polartec’s Power Wool is a quantum leap in next-to-skin fabrics

having worn capilene, various merino wools, maybe every form of Powerdry, Powergrid and Power stretch and like everyone, the old school poly pros, Power Wool is as close to getting it right as has been achieved. now into 2nd and 3rd generation versions, some of the issues have been worked on and what now exists is impressive.

what matters is that the entire clothing ‘system’ rests on the foundation of the baselayer. compromise it and that $700 jacket is off to a poor start. baselayers need to fill a range of functions much more sophisticated than the other layers, so stakes are high, and as it goes Power Wool is as big – if not a bigger – leap in function that Neoshell or Alpha.

the way Power Wool works is straightforward: the inner side is wool that has a degree of insulation yet allows heat to dissipate consistantly, and the outer side is a synthetic fiber that wicks efficiently and allows moisture to pass thru unimpeded.

how they’ve made it work is very sophisticated: this is not 2 layers stuck together. evolved from Alpha-style technology, Power Wool is a bi-component 3D knit (not a traditional weave) thats the one layer but with 2 sides to it. the wool inner side is a waffle texture, the synthetic outer side is a denser uniform texture.

beyond all that are the properties of the fibres: the wool doest reek, it keeps your skin in good condition and it gives a firmness to the fabrics dynamic. the synthetic element gives it durability, provides most of the wicking properties and retains the elasticity of the ‘firm stretch’ factor that makes it fit so well.

speaking of which, the fit is a major factor at work here. firmer than a normal high-stretch baselayer but not prone to the stretch degradation of wool, Power Wool acheives much of it function by form fitting alone. it sits tight against the skin to have maximum thermal and wicking efficiency, but has minimal bunching around the joints or riding up like many tight layers do. perhaps the best factor is that by combining wool and synthetic 3 dimensionally theres no need for a patchwork of ‘body mapping’ panels – which means construction can be kept simpler and more durable yet function is heightened. this then leads to more sophisticated design possibilities ie, how panels conform to the body, where zips go, ways of connecting panels etc.

Power Wools body-conforming ability makes it super efficient: it stretches but doesnt sag, sitting firmly against the skin but not loosing integrity with use

in use Power Wool is a true ‘put it on, leave it on’ fabric – which is vital for a baselayer. the days of stripping to a baselayer yet still sweltering are a big step closer to being over. Power Wool doesnt work by being thick – it works by being efficient, which means it’s almost neutral to the touch. as a single layer it will work comfortably well into warmer temperatures. this is largely increased by it currently being produced in a silver-grey that reflects radiant heat well. this stuff is as much sun layer as it is warmth layer.

on extended trips Power Wool has the odour minimizing properties of any wool, with the quick dry properties of synthetic. the minimal amount of seams needed to achieve high function also makes a garment with less pieces to come apart. over time is where the stuff really come to the fore, allowing the other layers in the system to maintain their functions too, remaining less compromised by the effects of grime as a trip wears on.

all this could only be done by Polartec, the only company working on a full spectrum of functional layers. they realize that for Alpha, Powershield, Neoshell etc to work properly they need to be on top of a foundation layer that gives them the best possible chance. of all the layers it’s taken the technology for Power Wool the longest to emerge, and in producing it theyve reinterpreted how baselayers can function.
