Huh? What backpack???

    Fantastic backpack! First break in was on a 30 mile cruise around Three Fingered Jack in Oregon's Mt. Jefferson wilderness. 24lbs at 10 miles a day were a complete breeze, the pack pulls tight to the hips very comfortably with tons of adjustments . I'm 6'1 220 and the md/large worked well for me. Took a few miles to figure out the right adjustments for me but when I did it was a breeze.

    Good bag

    • Familiarity:I've put it through the wringer

    This bag has seen a few 14k peaks for 2-3 day climbs in all sorts of conditions. Its light so you don't have to bring a separate summit pack but spacious enough to carry all the gear you need and it expands quite a bit at the top. Great choice for fast and light alpine action.

    Mountainsmith Haze 50 Ultralight Backpac

    The Haze 50 is a minimalist toploader, weighing in at less than 2 lbs. It delivers exceptional trail performance at half the weight of a traditional internal frame pack.

Using a modified version of the Mountainlight suspension system, this pack utilizes the DWR coated airmesh foam for increased breathability, and innovative ICS Cup (Illiac Crest Shelf) hipbelt that transfers and locks the pack load onto the hips and the Lumbar Control Point? pad on the lower backpanel to fully secure the pack load against the user's major weight bearing point, the lumbar/sacrum region. Pair the Haze 50L Mountainlight backpack with our Mountain Shelter LT and you have a pack/shelter combo coming in at an astounding 4 lbs

    Great Pack for the Lightweight Inclined

    • Familiarity:I've put it through the wringer

    This is an awesome pack that weighs in at under two pounds. With a top loading drawstring closure top this pack makes it easy to stow your gear. The two outside zipper pockets are good for things like your water purification pump or some snacks for breaks on the trail. There are two DEEP elastic mesh pockets on either side of the pack for your water bottles, and these pockets make a 1L Nalgene Bottle disappear (I repeat DEEP). This pack also has top and bottom strap attachment points for stowing your sleeping pad, sleep system or tent. The Haze also has Compression straps , Yellow daisy chain style attachment point in center of two zippered pockets, trekking pole attachment points (yellow draw cords) and interior hydration bladder carrier. Most of the pockets and attachment points on this bag are multi-use, which is what I look for in everything I buy.

    What are the measurements size-wise for this pack? I need for a small or extra small woman (about 15 inches)


    I am not sure exactly what measurement you are looking for. The weight, dimensions, and volume measurements for this pack in both S/M and M/L are listed with the tech specs on the left side of this product page. If these are not what you are looking for please let us know more specifically what measurement you need on this bag and we will find that out for you.

    Would this hold a Bearvault (BV500) inside?...

    Would this hold a Bearvault (BV500) inside? Unfortunately, I have to carry one. Thanks.

    The Bear Vault BV500 Bear Resistant Food Canister dimensions are 8.7" x 12.7" while the Mountainsmith Haze 50 Backpack has dimensions of 11.5" x 23". I think the BV500 should be able to fit in your pack just fine, but of course, that will depend on what else you are trying to put in there with it.
