Patagonia Terravia Pack 36l

The Patagonia Terravia 36L steps up from its 28L sibling with a removable internal frame — spring steel rather than a fixed sheet — and a roll-top-plus-lid closure aimed at multi-day trips of three to five nights. Weight climbs to 1066 g, or about 29.6 g per liter, reflecting the added structure and volume needed for overnight loads rather than day-hike gear. The fabric steps up too: 140D 100% recycled ripstop nylon on the body and 210D recycled polyester on the base, both PU-coated and PFC-free DWR treated, all bluesign-approved. A ventilated foam back panel, padded hip belt with pockets, side compression straps, and bungee trekking pole loops round out a layout aimed at trail comfort over multiple days rather than fastpacking speed. Patagonia backs it with a lifetime free-repair program, a durability signal worth noting for gear that will see repeated overnight use. This pack targets multi-day hikers who want a conventional, comfortable carry system in recycled materials rather than the lowest possible base weight — it's a capable trekking pack, not an ultralight one.
