We always strive for total performance and total innovation, but sometimes we surprise ourselves. This NanoFlex 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 effective thing we’ve ever made for keeping you comfortable in all conditions. It’s just barely short of a miracle.
Water-resistant NanoFlex fabric.
Same breathability, stretch and warmth as our standard Thermoflex warmers.
Great in every possible condition.
