For that reason, external-frame packs have largely been relegated to the lower end of the market, hence the price differential. Dana Designs tried to take external-frame packs upmarket several years ago with some brilliantly designed, exceedingly comfortable packs (the Longbed and related models, which sold for around $250), but the effort didn't get far and the packs were discontinued. Kelty still produces a high-end external-frame model, called the 50th Anniversary pack ($260; www.kelty.com). For budgets, JanSport's Carson 90 ($100; www.jansport.com), mostly marketed to the Scouting set, is lots of pack for the money.
That said, good-quality internal-frame packs can be had for under $200. Lowe Alpine's Appalachian 65 ($149; www.lowealpine.com) is a proven performer that can schlep big loads. So, too, is the Canadian Serratus Alpinelite (about $180 U.S.; www.mec.ca). And there's always REI's Mars ($195; www.rei.com), new this year and a very well designed backpack, with an excellent suspension and good packing options.
As for fit, you're best off in the hands of a good pack-fitter in a shop. Packs are a lot like shoesnot all packs fit all people. But most packs are also highly adjustable, so it's perfectly feasible to order one off the Web and fit it yourself. You can do so in your house with various things stuffed inside for ballast, and if you find it just doesn't work, you can always send it back into the cyber wilds from whence it came.
