The Terra Incognita Discover is an expedition hiking backpack offered in 55L, 70L, 85L and 100L volumes, built around the TCS TORSO suspension system for multi-day loads. It is designed for backpackers and expedition trekkers who carry heavy kit over long distances and need a pack that adjusts to their back length and ventilates on the climb, framed in abrasion-tough 600D ripstop with a reinforced 1680D nylon base.
Who is the Discover backpack built for?
The Discover is for serious backpackers, expedition trekkers and anyone hauling a heavy multi-day load. The 55L handles fast-and-light trips and lighter kit, while the 70L, 85L and 100L step up toward extended expeditions, cold-weather gear and shared group equipment. Because the harness and hip belt both adjust, it fits a wide range of torso lengths, which makes it a strong choice for hikers who have struggled to find a large pack that actually fits.
What is the Discover backpack made from?
The main body is 600D polyester ripstop, a fabric chosen for its balance of tear resistance and weight, while the base is reinforced with 1680D nylon FTX to survive constant contact with the ground. At a base weight of 6.39 lbs in the 55L, the pack puts its mass into a supportive frame and durable shell rather than trimming grams. The TCS TORSO system underpins the carry, keeping heavy loads controlled.
How does the Discover backpack feel on a long haul?
Loaded for a long haul, the Discover keeps weight riding on the hips through the V-strap belt while the ventilated back panel moves air across your spine on the climb. Dialling the shoulder straps to your torso height stops the load from sagging or pulling back on descents. When you reach camp or a summit push, the removable top lid detaches to serve as a compact daypack for the lighter kit you need close by.

Questions & answers
Discover backpack FAQ
What sizes does the Discover backpack come in?
The Discover is available in 55L, 70L, 85L and 100L volumes. The smaller 55L suits faster, lighter trips, while the larger sizes are built for extended expeditions and heavier multi-day or cold-weather loads.
Does the Discover backpack fit different back lengths?
Yes. It has a height-adjustable shoulder harness plus a V-strap adjustable hip belt, so you can tune the pack to your torso length. This adjustability helps it fit a wide range of body sizes for a stable, load-bearing carry.
How much does the Discover 55L weigh?
The 55L version weighs 6.39 lbs. That weight reflects a supportive TCS TORSO frame and a durable shell, since the pack is built to carry heavy expedition loads comfortably rather than to be ultralight.
Is the Discover backpack durable?
Yes. The main body is 600D polyester ripstop for tear and abrasion resistance, and the base is reinforced with tough 1680D nylon FTX. That construction is made to survive rock, brush and being set down on rough ground.
Does the Discover backpack have a ventilated back?
Yes. It uses a ventilated back panel that channels airflow across your back to reduce sweat build-up on sustained climbs, which helps keep you cooler and more comfortable under a heavy load.
