Sacrifice Comfort for Lightweight

  • Familiarity:I've put it through the wringer

Well, I'll confess that the mention of Ueli designing this pack was a selling point for me, sow was the discounted price too. That said, the pack is what you would expect from Speed Climber. It is super lightweight and simple, no real bells or whistles about it, except for the weight.

My only real complaint is that its not the most comfortable pack. However, frankly, when I use this pack for short and light outings, so the comfort doesn't bother me too much.

Good enough for me and Ueli

  • Familiarity:I've put it through the wringer

I didn't realized how much extra weight I was lugging around with my current stable of packs until I bought this one. The minimalist lightweight design is pretty great and surprisingly durable. It's comfortable to wear and holds enough gear for a few nights out in the backcountry. Works great as a follower bag on multi pitch climbs.

Great Pack

    This pack is great for short trips. Unless you are an ultralight backpacker, this pack will likely only allow you a trip of up to 3-4 days (depending on the circumstances). It is large enough to fit a lightweight 1 man tent, lightweight sleeping back, few days worth of food, a couple water bottles and the other small items you would bring on a short trip. If you attach a water bottle to the outside it leaves more room for food. It is very light and the built in "sleeping pad" (very thin but enough for decent terrain) saves space as well. It is not a problem that there are no pockets, simply bring a small dry sack to put small items in, if needed. One of my best gifts to date.

    Great customer support

      My first impressions on receiving the pack were that the ice axe loop on the left side was missing an elastic adjustable tie down device at the bottom attachment point, and that the hip belt strap was way too long. I contacted Mountain Hardwear customer support and they responded promptly and helpfully, arranging for me to return the pack for alterations at no expense. They are going to shorten the belt and finish the end professionally and also send me an extra elastic tool attachment device.

      Yes, generally, people cut off extra webbing/straps. The excess is for people who spend more time on the couch than on the trails. I'm a 32" waist, so I always end up shortening my straps, not a big deal. Doesn't void warranty or anything.

      just cut and flame the raw edge to prevent fraying. Pretty standard.
