Mystery Ranch T-100L Backpack

Colossal, massive, huge. All these are worthy descriptors of the Mystery Ranch T-100L Backpack, a durable pack that’s more than ready to tackle solo thru-hikes, extended treks in the backcountry, and expeditions through the great ranges of the world. It has the same basic silhouette and design as its younger brother, the Terraplane, but is sized to handle your boldest backpacking adventures.

This massive pack has enough room to keep you well-stocked when you know you won’t be able to resupply for many days or weeks. The top-loading design helps you pack efficiently and the side-access zipper lets you reach items on the bottom without taking everything else out, which is pretty important when you have enough gear to fill this thing up. Meanwhile, Mystery Ranch has updated it with their Astral Frame. Already used in their military-grade packs, it ensures support and stability so you can carry extremely heavy, bulky loads comfortably over technical terrain. Plus, if you want to head out on a short day hike after you’ve established base camp, the detachable lid can be equipped with the detachable yoke to create a decent daypack.
