We at Bull-it Jeans ride, we raced, we love bikes. We work with Superbike teams, Flat Track, Long Track, Speedway riders and stunt riders, not foretting the Fire department and Bike Safe Police Teams - all with one thing in common - people exposed to high speed offs, Bull-it and Covec work together as solution providers for all. Working with Covec™ for 2011, we’ve been designing materials fit for the purpose, fit for Bikers. Aramids are great yarns, but not the ones for Bike jeans. They have many weaknesses, degradation through hydrolysis, Flex bending (fatigue), yarn on yarn abrasion and UV, as long as you don't bend your knees or your butt, wash in warm water, use a washing machine or dry in the sun you will be fine..... Other high performance yarns typically abbreviated High Modulus Polyethylene's (UHMPE or HMPE), probably the last thing you want in your pants, unless you like 3rd degree burns. It has high thermal conductivity and passes road heat (friction heat_ straight through to the skin, these are the fastest melting yarns. Avoid Polyesters and Polyamides too for the main protection materials, that are some fancy material names out there right now, but apart from Covec there are no other materials invented purely for motorcycle long life performance. Well, that’s what we at Bull-it Jeans are about. Bikers making technical clothing that looks the nuts for bike nuts.
