Purna ProteKt Windproof

The Purna ProteKt Windproof shell jacket is so thin you'd expect it to tear at the first brush with a prickly bush but it has proved me quite wrong. Weighing 99g including carry sack, it's designed to be donned in a flash, protecting against wind chill whether screaming along a mountain pass or dribbling through Drabsville.

Fabric wise, we'an ve a Pertex shell that blocks cold air, yet still allows rider generated stuff easy escape via a clever capillary action, having the added benefit of drying in a matter of minutes. Unlike classic 'condom' capes, because the pores allow efficient moisture management, it can also be worn between base and jersey.

I liked the fetching colour options but night owls may want to add some Scotchlite - I was a little bit disappointed at the lack of reflectives.

Sizing seems on par with everyone else's, taking the guesswork out of online purchases - our large was snug enough to prevent billowing without feeling remotely constricting over winter layers. When not required it packsinside its stuff sack, which is also made from Pertex and tethers pretty unobtrusively to top tubes or in pockets. The sack also doubles as a nifty stash for energy bars/patch kits/loose change when empty.

Decent zipper tags make it easy to get on and off on the fly. Cowering low, there's a curious sensation as winds ruffle the outer fabric, trying to tease a way inside but ultimately remaining cheated despite the unlined collar. Sustaining race pace for an hour or so hasn't left me remotely stinky, although when it comes to the damp stuff, persistent, light drizzle is pretty much the limit.

Verdict

Surprisingly rugged windproof shell with great cut and good colourways. Light drizzle's the limit though
