Mountainsmith Circuit 5400 Review

"it has been one of the most comfortable packs i have used. it took a while to find the best (read most stable) way to load, but carried the 50lbs of gear quite well. the top pocket/day pack is awkward to wear and doesn't fit well over the drift collar of of the pack. I would recommend this pack as a large pack as it doesn't lend itself well to light or smaller loads"
