Very comfortable

Nice pack, holds up to abuse, large enough for me to do several days, or about a two dayer with kids. great suspension, no problems or hot spots while hiking with about a 25pound load.


    A lightweight version of a very classic pack design. All the features you need, none that you don't. It saved me about 2 lbs over my previous Deuter pack with no loss in comfort or functionality.

    The Dyneema ripstop grid/nylon base material is a great compromise between durability and weight. You won't shred it by hauling it up a chimney or two unlike some of the other ultralight packs out there. I couldn't find the denier spec for it anywhere but it feels about the same as other 210d packs that I have. The build quality and stitching are excellent and the pack feels like it is built to last.

    The suspension is comfortable up to 30-35lbs. It has a U-shaped stay which is about 5" wide, plus a framesheet. The hipbelt has thicker foam at the top than the bottom to keep it on your hips. One thing to note is the waistbelt is pretty large: I am 5'10 175lbs with a 33 waist and the waist straps bottomed out at the end of their adjustment range. I took the pack to a local tailor and had him take a few inches off the waistbelt strap attachment which made it work just fine (cost: $12.) The torso length for me was perfect which is good since there's only one size and no adjustments.

    There is a compression strap going from the haul loop to the front of the pack which you can use to secure a rope to the top of the pack. The lid is really well designed and is gusseted so you can actually get stuff in and out of the top pocket when the main pack body is stuffed 100% full (this always pisses me off on my other packs...) The plastic trekking pole holders work well. For winter usage you could fit two tools on the back instead.

    If you like this pack you might also check out the very popular Osprey Exos 46 which is 4oz lighter & with the funky air mesh suspension. I chose this one instead because (1) it fits a bear canister way better, (2) the fabric felt more durable, and (3) it has way more useable space inside even though there's only a 4L difference in stated volume. There was no way I was going to fit a bear canister+overnight gear+alpine rack in the Osprey, and that stuff fits fine in the Zepton.
