    Was impressed with the original thermaflex.
    However Rooster have nailed it with this one loosing the Velcro strap at the top which was never needed. Also instantly felt like a better fit around calf and ankle which should mean alongside grip inserts on the inside it will be unlikely to rise up. All in all make sure you get some of these alongside a top and you can use all through spring, summer & autumn!

    Super flexible, comfy, great knee protection. New non velcro shoulder straps are great as there is no abrasion on your shoulders
