I'll test this pack for my upcoming CDT hike. I know all my gear will fit inside. Now that the extra strap length is removed, its a custom fit. I also removed the fabric sleeve at the bottom.
Its important to heat seal every strap you cut. Make sure to fold back the edge, too, or it could slip through the buckle. Leave enough for adjustment in case you are wearing a bulky jacket or gain a few pounds....not likely on the trail.
At 2 pounds 12 ounces, this 3000 cubic inch pack is sweet. Stay tuned for more gear choices.
