Last weekend I stopped by a local tactical shop to see what they had to offer. One of the bags that I went over was the Arc'teryx Blade 21. One was black, the other was "Universal" camo. The camo one had LEAF stitched on the front, the black one did not. The bag is pretty light overall, with very plushy padding on the shoulder straps. Easy to get into. The back is a kind of a hard foam, which is further reinforced with the removable insert inside of the bag. The bag is a little on the small side for EDC( 1280 cubes), but has a unique side-loading design. I am sure that it would be great for books, papers and whatnot. The quality of the bag seemed to be high- definitely "brand-name" stuff. However, I was disappointed in a few things. 1.) The foam backing+insert made me feel like I had a turtle shell on- YMMV. 2.) The pack material was high quality, but much thinner in texture. Their site says: 1260d Ballistic Nylon/630d Superpack nylon, but it felt far softer than 1000D Cordura. 3.) The side-load design- good idea, but not a lot of people will use it as intended. Since I hold my packs on the left, this doesn't work for me. 4.) I had read on several sites that their LEAF line was made in Canada. This is not true any longer- both packs were made in the Philippines. So, I'd give the pack a B- not for everyone, but still good quality.
