Sierra Designs Rohn 15 Backpack

www.sierradesigns.com, one pound, 13 ounces
Backpacks have a simple mission: To carry your stuff, comfortably, in stable fashion, with no more weight than you need. For day packs, that should be easy; but most are heavy on doodads, and too unstable for sports like trail running or skiing.

Not so this deceptively sleek 15-liter panel loader, built atop a plastic back panel covered with large foam and mesh bumps. The back panel, along with a wide, soft waist belt, makes the Rohn very stable, even on bouncy trail runs with a partial load and a full 100-ounce bladder. It hugged our backs without getting super sweaty, even with southwest monsoon humidity on 100-degree day hikes, thanks to huge air channels. “The die-cut shoulder straps were wide enough to be comfortable even when I was hauling 20 pounds of water, ropes, and carabiners into tight slot canyons,” one tester noted.

Useful features included mesh bottle-wand pockets; internal pockets and sleeves for bike pumps or avalanche probes; a single outside pocket large enough for goggles, with a key clip inside; twin hip belt pockets sized to hold smart phones, GPSunits, or four energy bar apiece; an internal compression system for the hydration pocket that could be tightened via a cordlock on the right hip, bike light attachment points, and a removable bungee net on the pack front to help augment capacity.

The packs’ bullet shape stayed out of our way on diagonal stride cross-country skiing and chairlift rides. Its combination of simplicity, stability and all-around utility has made it the go-to day hauler for our primary tester since he began using it in March of 2012.
