HOW DO THEY DO THAT?
We always strive for total performance and total innovation, but sometimes we sur- prise ourselves. This Nano Flex fabric behaves just like our Thermoflex fabric in dry conditions, but then provides unbelievable water repellency when it starts raining. We donâ€™t claim that itâ€™s fully waterproof, but itâ€™s the most ef- fective product weâ€™ve ever made for keeping you comfort- able in all conditions. Itâ€™s just short of a miracle.
- Water-resistant Nanoflex fabric
- Same breathability , stretch, and warmth as our standard Thermoflex warmers
- Double-sided Silicone grippers keep the warmers in place
- Great in every possible condition
