In its Boa product series, Evoc uses the Boa tightening technology familiar from many top-level sports shoes. Boa is easy to use and safe - you don't have to play around with Velcro or buckles. As with handlebar-mounted bags in general, you should use it to pack stuff that can't be damaged by shaking - from the point of view of equipment, a handlebar mounted bag is almost like a washing machine's centrifuge. The width of the bag is suitable for use with straight, curved and traditional handlebars, i.e. it can be used with road, mtb, gravel, hybrid and many other types of bikes. The fastening system easily navigates the bunch of hoses and cables on the handlebar. - Waterproof construction and seams - Roll closure at both ends: the width of the bag can be adjusted - Elastic band for slipping accessories or e.g. a windbreaker underneath - Air vents help to let excess air out when closing the bag - Boa tightening keeps the bag in place - Reflective logo
