Seam welded, to keep water out and provide maximum protection for contents. Constructed from high quality materials and optimized for durability and weight. Designed to make use of the space below the handlebars, eliminating the need for a front rack. Handlebar Packs are made expressly to carry the light, compressible and bulky items of your long distance adventure, or multi-day bikepacking kit to create a larger and more balanced load on multi-day adventures or when tackling steep climbs and technical trails. This Pack has been designed to keep water out, even in a sustained rain. The product features a hassle free air release vent and is therefore not submergible.
