Define Hydration Compatible

    Great looking and feeling pack. Expands nicely, light weight and feels very durable. I bought this to replace a NorthFace bag that was not hydration compatible, which this bag is stated to be so. In my humble opinion "hydration compatible" means it has a pocket/ pouch to place your bladder into and also a spot for the hose to route through near the shoulder. This one has the hole for the hose but no place to put the bladder and no intuitive way to even hang the bladder in the main compartment. Not a lot of padding on the shoulder straps but this bag isn't meant for heavy loads so that shouldn't be an issue. I do really like the way the closing and opening of the main compartment operates with the draw-chord. I'll be wearing this weekend during some crevasse rescue training and may update with more information at that time.


    • Familiarity:I've put it through the wringer

    I searched a long time for a backpack that would fit all of my needs: I use it for textbooks, running clothes, and lunch when I am at school, as a crag/alpine pack, and can load up a few days worth of groceries in it, too! This pack is great for bike commuting. Finally found a pack that does it all.

    I've used the pack now in both rain and snow, and while definitely not bomb-proof, it is fairly water resistant. I would probably recommend a cover for extended use in wet conditions, although I haven't personally felt a huge need for one. Hope that helps!

    will this backpack hold skis for alpine touring?

    Does this pack have an internal frame? The description doesn't specify. Thanks for any help!

    Sort of. The picture on mountain hardwear's website really does the best job of explaining. But its basically a corrugated like piece of plastic. Looks sorta like a washboard. It flexes more than a traditional frame but might not provide as much support. Really comfortable though.,default,pg.html

    How small does this pack compress down to? I have an Osprey Argon 85 and want a light daypack for peak bagging that won't take up too much space in my bag. I'm comparing it to the smaller (20 L) Marmot Ultra Kompressor. Any insight would be helpful. Thanks!

    bef. Instead of the TRL 30, check out the ULT 30 as it is the ultralight version of this pack. The TRL 30 weighs 1Ibs. 10oz. and the ULT 30 weighs in at a svelt 14.1oz (!) Both packs have a Hardwave framesheet which is removable for ultimate compressibility but 14.1oz for a 30 Liter pack is pretty light! The 100D High Tenacity Dobby Nylon is some of the most durable, lightest weight, and compressible fabric that we use in our packs and would be the perfect companion to your Argon 85. I hope this info helps!!

    Is this pack Hydratation compatible?, kinda important information when ur purchase a pack

    It has side "bottle" pockets. It doesn't have a slit for a hydration port but I have one or two bags with that problem and it has never prevented me from using my water bag. I just run the hose around the outer side of the top, or cut a little hole with a knife. I can understand not wanting to cut your bag, to each their own.

    I hope this helped you!

    Phil. If you look on the right of this page at the 'tech specs' you will see that it does mention that the Scrambler is hydration compatible. There is a sleeve along the back inside of the pack that is designed to hold of variety different sized hydration bladders. I hope this info helps. Enjoy!
