Mountain Hardwear BMG™ 105 OutDry Backpack USED Tier 3

- +


This is a TIER 3 USED item, meaning it has been pretty well loved and seen at least a season’s worth of use (at least 10 climbs on Rainier). This means it could have moderate use: stains, scuffing, pulling, discoloration, very minor rips and tears, dirt, etc. NO: broken zippers, buckles, straps, or mesh.

 All items that were once part of our rental fleet will be numbered with black sharpie on the inside, regardless of condition. If you have further questions, feel free to check our Gear Cache page, or contact us! Also, keep in mind our return policy is different for Used gear!



This pack is GUIDE PICK for Denali, Aconcagua, or any trip where you need to haul more than 75L. Designed for professional guides to comfortably haul heavy loads on long treks. Flexible design and compression system ensures this pack can grow-or shrink-according to your needs. OutDry construction bonds a durable waterproof membrane to the main compartment so that your gear stays safe and dry in even the wettest conditions.

This pack's clean design makes it easy to manage even when the climb gets tough.  Quick-release ice axe attachment points, gear loops, and easy access zippers are all benefits on a longer expedition.  The BMG's sturdy frame will help keep the weight of an expedition load resting comfortably on your hips.

Size Chart

Pack Frame Size
Your correct frame size is found by measuring your torso from the seventh vertebra (the big bump where the shoulder slope meets the neck) down the spine to the point in the small of your back which is horizontally level with the top of your hip bones (iliac crest). To find the iliac crest, use your fingers to trace the hip bone upwards until you can feel the point where the top edge of your hip bones curve inwards, on the side of your hip, creating something of a shelf. Holding your finger on the seventh vertebra, measure down your back to the point in the small of your back level with your iliac crest. The measurement is most easily obtained using a string or a cloth tape and help from a friend. This is your torso length, and using it, you can now select the correct frame size.
