The highlight of the X-BIONIC® SymbioStream jacket is the spoiler on the back, which creates a negative pressure during the ride and sucks out moist air. Is the cyclist not in need of a jacket, it can easily be stowed in the spoiler and be placed on the frame of the bike. Due to an intelligent air duct, the jacket dries during the ride. The material is also new. The symbionic SuperLite membrane of X-BIONIC® offers a water column of 20,000 at a low weight of only 56 g / m². In contrast to PTFE membranes, this closed membrane is able to transport moisture to the outside in droplet and vapor form.
