Mystery Ranch Radix 31L Backpack

The RADIX 31 was designed knowing a little less weight can make your mountain mission a whole lot better. Crafted from lightweight Ultra-PE Birdseye and durable, recycled Robic Ripstop fabric, this pack takes the edge off those grueling ascents without sacrificing toughness. An array of adjustable features, like a removable frame, and plenty of external pockets helps you master the game of cubic inches. And the option of women’s or men’s harnessing provides a natural and comfortable fit.

Comfy, light, and yet beefy

I just got this pack today and haven't used it yet, but I'm in love already. I can tell it will be really comfortable with heavy loads. Love the hip belt pockets for easy access while hiking. I also really like the outside compression straps in order to cinch down smaller loads. I needed a pack this size that is a bit larger than a day pack. It will be perfect for an inn to inn hike I'm doing in Solvenia in the fall. This pack will easily accommodate a 1-2 night hike. My only nit-pick is why no small zipper pocket on the lid? I'll be taking this as carry-on, and having an easily accessible but secure pocket on the outside would be nice for passport, wallet, gum, phone, etc. I didn't even notice it didn't have one when I was looking on-line. My bad, that's on me, I'll figure something out.

Light weight, but still carries weight comfotably

I have an older version of Coulee 40 which I use regularly. It is super durable and I live the tri-zip access...but it is a bit on the bulky/heavy side. I swapped out for the Radix 31 and have used it on several hikes. I've loaded it with around 35lbs for testing and it carries very well. It feels a bit more comfortable than my coulee. The shoulder straps sit better and the pack seems to move with me better. I'm sacrificing a bit on ease of access into the main compartment, and there is no brain, but it's worth it for the weight savings and comfort.

Great pack with so much potential

I got this about a month ago. I have used it on three long day hikes so far. The build quality is up the Mystery Ranch's high standards, materials are holding up great for off trail bushwhacking in the Canadian Rockies. Simply love the Coulee style Yoke setup, super adjustable for the perfect fit.
