Our Nano Flex water-repellent fabric is one of those fabrics that seems miraculous. On a dry day its as warm and breathable as our normal Thermoflex fabric, but when it rains the water just runs off, thanks to the five phase nanotechology treatment. While its not 100% waterproof, its the best soloution we have ever tried for staying comfortable in any conditions. On a wet day pair the NanoFlex bibshort with our NanoFlex knee or leg warmers for the same level of warmth and protection as you would get with tights.

So you race cross? Do you train in the rain? Do you go home if its a cold damp start to your race? Have you ever done a sportive in changable conditions? Just imagine a high quality bibshort with the renowned Kiss 3 seatpad that actively sheds water thats still as stretchy as a standard lycra short oh and also has a little bit extra warmth..... Its here so where sorry we have taken away all your excusses....
