Extremely well built pack - Mystery Ranch Metcalf 4335 cubic in Backpack

Mystery Ranch makes some really durable packs. I bought a bigger one a few years ago (the Marshall, I think) and absolutely love it. The Metcalf is smaller (4300 cubic inches vs 6400 on the Marshall) but it’s still a large pack. The frame, straps, and belt are really comfortable and adjustable. Heavy loads are no sweat. I like pockets on my packs for the smaller stuff and the two up top are perfect. All the heavy fabric, zippers, and adjustment straps add to the overall weight of this pack so that’s not one of its most enviable features, but durability sure is. This is military grade equipment.
Does anybody else think retailers could make it easier to compare pack sizes? Cubic liters, cubic inches, CCs. And often no pictures on a human. Makes it tough to know what you’re buying. Anyway, I’m very happy with what arrived!
