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 don’t claim that it’s fully waterproof, but it’s the most ef- fective product we’ve ever made for keeping you comfort- able in all conditions. It’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
