Klim Arsenal 15 Technical Motorcycle Backpack The Arsenal 15 Backpack is a medium capacity pack in our lineup of off-road, dual-sport and adventure riding bags. Load compression and stability while riding were key build objectives, along with exceptional venting for hot weather conditions – all leading to extended comfort and a better ride. As is KLIM tradition, we built the Arsenal 15 with durable materials and incorporated useful features like the removable rain fly, a tool pack and harness, pockets that fit fuel bottles, hydration bladder and more.
