Needs work

  • Familiarity:I've used it once or twice and have initial impressions


I have about 15 trail miles on this pack carrying ~33 pounds. I'm not that impressed.

The main problem is the weird hip belt. As the other reviewer says, the belt straps are oddly short, though I could close the snap over my 34 inch waist. The concept behind the belt shape sounds good, but the execution is lacking. The iliac crest hip pad sits far higher than the lumbar pad on the back panel. So either you have the hip belt on your iliac crest (hips) and the lumbar pad ends up way down over your coccyx (butt), or you put the lumbar pad where it belongs and the hip belt squeezes you in the middle of your stomach. The lumbar pad also sits on the trampoline panel so it just flexes away from your back. The result is that the pack weight seems to rest on one narrow ridge at the bottom of the lumbar pad. Since the trampoline does not follow the contour of your back the only other contact point is at your shoulder blades. A normal hip belt and some contour to the trampoline would fix these issues. There are some neat ideas worked into the suspension but the execution needs some refinement. This thing feels beta.

The pack body is held away from the trampoline excessively so the load is like 4 inches behind your back and pulls away from you too much. Many trampoline packs experience this but the Ghost more than most. The zipper on the main pocket is also anemic and has already closed with the zipper teeth not aligning correctly a few times when pulled over lumpy contents, which leads to a blown zipper and your stuff spilled all over the hillside. The 'pockets' on the hip belt are too tiny to be of use. You will maybe get a chapstick in one and a powerbar folded in half in the other.

There are a lot of packs on the market. I'm not sure how this one will be able to compete.

I want to give this five stars...

    I have the old Ghost, and being a fan of it, and someone who suffers from a sweat soaked back even on the coldest of days in the most breathable clothing possible, I was stoked to get this pack...

    However; the waist belt is just too damn small. I wear a size 36/38 and with the waist belt I can just BARELY cram it shut, thus making it pretty much worthless. Four more inches would have saved the day... I'm going to try and find some SR buckles and make an extension...

    HI Nick,

    I am the Mountainsmith rep for The belt is unique for sure. First on the size, there is actually an adjustment that can be done. The belt hip pads can be extended about 2-3"on each side by releasing some velcro and sliding them up. This may help with the length. Also, because the belt is unique, we have seen many cases where people are positioning them a bit to low. So, you may want to make sure it is high enough on your hips. Because when in the right position that lower lumbar support really hugs your back and the belt just grabs the top of your hip and holds it there.

    Hope this helps!
