Kelty Trekker Backpack - 3900-3950cu in - 2009 BCS

Jeremy, This pack would fit you fine, but before buying anything I would also take a look at the internal frame brother of this pack, the Kelty Cyote. It is in the same price range, but gives you a fully internal frame pack with most of the same features as the more expensive top tier packs.

I prefer internal frame packs simply because they do a better job of protecting my gear, while still giving me the option to strap a pad or tent to the outside if I have to, though I usually find a way to get all of my gear on the inside

With that being said, some people still and always will prefer external frame packs as it gives them the ability to attach bulky or awkward objects on the outside of the pack without worrying about how they fit on the inside. It also gives them faster access to these objects, which can be nice for getting camp set up quick.

Good luck on your decision

This pack will be good for your size. It does depend on what gear you have and how long you are going out for. If for an overnight or a weekend you could carry all you need in this pack.

It all depends on you. This is only a guide. If you don't mind the pack riding an inch higher, you'll be fine. Actually one inch isn't that much. Two or more would become uncomfortable over longer distances. The first external frame packs didn't even employ waist belts. The entire weight was carried on the shoulders. We're all glad they evolved from that!

The 3950 fits a toso range of 16-22". The 3900 fits a torso range of 14-20". The waist belts are the same, you won't have a problem fitting your skinny waist! You're basically in the middle of each range, I'd go for the extra 50 cu in.

I have to agree with chris. External frame packs have their strong points (monster load capacity and tons of lash points) but today's internal frame packs are generally more comfortable and easier to live with. They fit more closely to your body and would probably be the better choice in the Cascades.

I would suggest walking into your nearest outfitter and trying on a few different packs before buying one. They'll get you set up for the correct torso length and help you sort out the features you might want in a backpack.

Frame packs are great if you plan on hiking on well maintained trails without low hanging branches. They're easy to pack and can haul a ton of gear. If you plan on doing a lot of hiking on uneven ground or off trail, I'd recommend an internal frame pack like the Red Cloud 6650 or Coyote 4750. Hope that helps.

The color and the material. This year's color does not look like an angry forest demon made the pack. This year's material is 600d poly ripstop vs. the old 210d poly ripstop. Last year's version is also 4oz. lighter. Unless you plan on putting the thing through a wood chipper or carrying swords, last year's model should do nicely.
