The new Jkt Boosted Proof, completely redesigned, combines extreme technical features with a clean and stylish look, perfect for both mountain use and everyday wear. It offers full wind and water protection with 20k mm of water column, while maintaining great lightness and breathability. It’s the perfect waterproof layer for the warmer months! It stands out from the rigid and bulky shells available on the market thanks to Dermizax fabric, incredibly lightweight and elastic. We use the 2.75-layer version: two and a half layers, with an added internal soft-touch treatment that increases comfort when worn over a T-shirt. Breathability is further optimized with the exclusive "Shark Vents" technology developed by Crazy: a direct ventilation system with reverse openings that allows air exchange while maintaining waterproofness.
