ION's Bikeshort Traze X is versatile and flexible yet rugged enough to withstand the rigors of trail riding. With its familiar comfortable cut, ION combines 4-way-stretch material on the back, where normally the most tension is created, and 2-way-stretch on the front. So you enjoy freedom of movement exactly where you need it most. Thanks to the hidden adjustments of the waistband, you'll find the perfect fit. ION's Air Flow technology combines highly breathable and moisture-wicking materials for perfect ventilation while riding. Triple stitched and taped seams provide the durability you want in a high-tech trail pant.
