Peter Macfarlane rates his Greener Choice after testing packs this season: the Patagonia Terravia Pack 36L.

The Patagonia Terravia Pack 36L is a roll top, which is a closure design I’ve always liked. Instead of a drawcord to pull tight under a lid, the top of the pack rolls down and is then secured by buckles. It’s simple, quick, weatherproof and allows for some extra capacity.

Peter Macfarlane’s Greener Choice

Even with a full winter Munro load the Terravia has been a very comfortable carry.
Pros
  • very comfortable to carry

There are excellent pockets on the front and side panels; and they’re divided by internal stretch gussets, which allows you to cram a little extra gear should you need to. The side pockets easily take a large bottle, which is accessible when the pack is worn. However, the compression straps run over the outside pockets, which interferes with bottle use. There are double ice axe and pole loops; but their upper bungee attachments sit next to the top compression strap buckles, making them hard to access if you have an ice axe on the pack. The harness is low profile with light padding and fits me well. Even with a full winter Munro load the Terravia has been a very comfortable carry.

The back system is a simple padded panel with an internal stiffening sheet, which gives the pack flex and holds it in shape if you pack it well. Inside is the bladder sleeve with two hose exits and the bag for the external zipped pocket. The Terravia has proved very water resistant – it sheds rain, and water ingress at the seams is very limited. However, the pocket zip is not a water-resistant type. It sits on the very top of the pack, so rain gets in and fills the pocket bag; this then filters into the main body. There is a rain cover at the bottom, but in use it’s only really the pocket zip that needs protecting. It’s something of an oversight that lets a otherwise excellent pack down.

How we tested

Peter used the packs for all his outdoor activities through the end of winter 2026, from light loads on trail day walks to long, loaded days on winter Munros.  This review was first published in the June 2026 issue of The Great Outdoors.
