With a layer of closed cell foam across the back of the hand but a single layer synthetic leather palm the Defend Thermo gives a good amount of extra warmth and weather protection for the colder months of the year without sacrificing any grip at the bar.
A compression neoprene cuff with velcro closure keeps everything secure and nylon gussets between the fingers allow stretch without letting the draft in and silicon print on the fingertip helps maintain a solid grip to the brake lever even in wet conditions.
