Great pack!

  • Familiarity:I've put it through the wringer

Bought this pack a few months ago and have used it plenty. It is a sturdy build with high quality components. A little on the heavy side at just over 4 lbs, but it's a work-horse! This isn't just a weekend pack. With smart planning, I can easily fit a week's worth of gear in this pack and it carries it very well. Everything cinches down very nice and compact, lots of airflow to the back while hiking in warmer weather. I would definitely recommend this pack!

A simple internal pack

  • Familiarity:I gave it as a gift but have feedback to share

I bought this as a gift for my sister, but put my hands on it a bit. Very high quality construction and simple layout for an internal framed pack. Great for beginners and the long weekend trip.

Mountainsmith Lookout 50 Backpack

The perfect weekend size backapck, the Lookout 50 can handle 2-5 days in the backcountry with a host of features to cover everything from your next backpacking trip to that winter hut trip to an adventurous canyon hike. With an extended volume of 64L, this weekend warrior will accommodate most any trip on your calendar and offer unmatched comfort and durability along the way. The innovative ICS Cup (Illiac Crest Shelf) hipbelt transfers and locks the pack load onto the hips, the Delta Wing Compression system pulls the load into the lumbar region and focuses on 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. All this while the Anvil Airway backpanel keeps you cool on the longest trail day.

What does it mean that this pack has an "extended volume" of 64L? Does this mean that this pack should be considered alongside other packs in the 60L capacity range, or am I missing something?

Many packs have a sort of storm collar that can be raised out of the top of the main pack which allows for extra capacity. For the Mountainsmith 50, the extended volume might refer to such an area that extends upward from the inner pack and causes the top pouch/lid to sit a little bit higher off the main pack. Probably, many top-loading packs have this feature.

So how do you adjust or buy a pack to fit ones torso? What do you measure to size a pack?

Best Answer

Most one-size fits all packs like this one have some sort of adjustment system that involves different attachment points or a velcro sheet that allows you to adjust the suspension system for a large range of torso sizes. As far as packs that require you to pick from torso ranges that are more precise go, with only a minimal amount of adjustment, you stand up straight and have someone else measure from your C-7 vertebrae (the large bump at the base of your neck), to a line that's the same height as your illiac crest (top of your hip bone). That measurement is your torso length, and that's what you'll use to determine what size pack you need.

As for this pack in particular, I would be very surprised if your torso length fell outside the 17-22" fit range, even at 6' 2".
