Kelty BRT USA

The Kelty BRT USA is a rolling gear trunk with roughly 172 litres of capacity and a weight of 6050 g — about 35 g per litre, which reads high next to a typical trekking backpack but makes sense for what's really wheeled luggage with a detachable aluminium frame and stow-away straps that let it be carried on your back when wheels aren't practical. That dual-mode design, wheels for pavement and trailheads plus backpack straps for rough ground, is the point of this category, distinct from a true hiking pack built for all-day carry. At over 172 litres, this is expedition or team-gear volume — well beyond what any backpacker would carry personally on a trek. Kelty markets it for travel use, and the removable frame means it can shed the pack straps entirely and function as pure rolling luggage when the backpack mode isn't needed. It suits base-camp resupply, guided trip logistics, or overland travel where bulk gear needs to move between a vehicle and a campsite, not day-to-day trail carrying.
