Carried this from Campo to Manning. Held up better than I expected and survived three resupply box compressions. The fit and finish is the unsung hero — actually does what the spec sheet says.

Loved it for shorter trips — but I'd size carefully. The reference fit ran a hair small for my torso and I had to swap mid-trail. Once I had the right fit, no complaints.

Bottom panel pilled to fuzz by mile 200. Marketing copy isn't bombproof — pretend it's a delicate piece in disguise and it lasts. Drag it across granite and it doesn't.
