Why We Like The MYSTERY RANCH Radix 57L Backpack
The MYSTERY RANCH Radix 57L Backpack is the versatile, durable companion with us when we show up in the parking lot with dirt, sweat, and a smile gracing our faces after racking up miles on the trail. The lightweight Ultra-PE Birdseye and Robic ripstop materials are built to handle any condition, ensuring our gear stays safe and compact no matter what the trails throw our way. The lightweight aluminum frame can be removed when we are prioritizing moving light and fast or be left in to provide structure for our gear. Compressible side and front pockets stash away our quick-access items like layers and snacks, and the front hip pockets hold our phone, GPS, and multi-tool. The adjustable harnessing options keep the bag sitting comfortably on our hips and provide a gender-specific, ergonomic fit.

Nice and light
I have not had a chance to take it for a hike yet but it seems like a great pack. Nice and light. I really like the larger outside pockets.

Exceeds expectations
I purchased this for my son who is preparing for a backpacking trip, and so far, we, as a family, are all very impressed with the quality of the materials used, the fit as well as the overall, very thoughtful, very intelligent design/construction. We're also sensitive to chemicals, and I'm happy to report that this pack is ideal in that way, too. Nothing noxious about it - whatsoever.

Hip belt slipping down
Hiked 20 miles in Olympic NP with this pack. The hip belt would slide off my iliac crest way more often than on my other mystery ranch packs. I think to cut weight on the pack the hip belt wings are smaller in height, resulting in less surface area to hold on to your hips and get that locked in feeling. To be far. I had to carry someone else’s bear canister plus mine in an already fully loaded pack. Everything else about this pack is great. If this pack had the endurance yoke like the Bridger series packs, it would be a juggernaut.

Its a great backpack
I have used several backpacks over the years and the radix 57 is my favorite. It is lite weight, comfortable and the external pockets allows easy access to a lot of gear as needed.

Great Pack, but nothing is perfect!
I've had this pack for a few months now and have gotten a few hundred miles under it with varying loads and equipment needs. From overnight fishing trips where I hauled my pole and tacklebox to multi day trips through rocky alpine trails, this pack has been fantastic. Mystery Ranch is the king of comfort, and is my go to brand when it comes to the majority of my trips. The robust hip belt, quality load lifters, and torso length adjusting system really lets you dial in the perfect fit. The only negative I can bring up on that point is I wish there was an option for the running vest style sported by the Bridger series. That running vest style REALLY helped distribute the load across your shoulders and brought your chest into the support system. If I'm hauling extra gear (fishing equipment, ice axes, gear for my dog, camera equipment, etc.) I really want the ability to spread the weight bearing across as much of my body as I can. I sometimes find myself eye-balling my Bridger 65 over my Radix 57 when I'm hauling my tripod and DSLR. This is not an ultralight pack, but its a good measure lighter than traditional-styles of backpacks while still managing to handle weight far better than most UL packs. The cost is competitive with packs of similar quality, though I feel like I haven't QUITE gotten my money's worth with this product as of yet. It's strong, fairly water-resistant, and has great space inside the bag with a comfortable diameter of the interior pocket. Though it's missing the great organization of the Bridger series, the brain and outer pockets of this bag offer plenty of organization for 99% of backpackers. I love the large side pockets that allowed me to fit a 1.5 L Hydrapak bottle and my trekking poles one side with my poop kit, camp chair, and 1 L Hydrapak bottle in the other. The open tube-style paired with the full length zipper really scratches the annoying itch I have with other-brand UL tube style packs where you nearly have to climb inside to access your gear at the bottom of your pack. Overall this is a great product for a MOSTLY fair price. I rated 5 stars on Value but in my eyes, it barely makes that 5th star. The state of backpacking gear is overpriced as a whole so I feel like I can't blame Mystery Ranch for just competing with the market. Plus I like buying American. You'd be hard pressed to find a pack that's THIS comfortable for this price to weight ratio.

What I expected from Dana.
This new pack replaces my Dana Design Terraplane bought in 1995. I just took it out on a 3 day trip in SW Colorado and am very pleased with this pack. The craftsmanship is excellent, which is expected from Dana. But, what I love are the outside pockets. These 3 pockets are roomy but can be cinched down to nothing if you don't need them. Also, the pack has a multitude of features that can shed weight if that is important to you. All of the straps, waist belt, and top pocket are removable. What is most important to me is the comfort and this pack is as comfortable and adjustable as my old terraplane. This pack distributes the weight evenly and allows the user to move weight from hips to shoulders while hiking.

I have the Radix 47 but am looking for something that is big enough for winter backpacking and for long trips upwards of a week. How does the size of the radix 57 compare to the 47. How big is the main compartment of the 57 vs the 47? How many more liters

Does Mystery Ranch Radix 57 own an internal hydratation pocket (dimensions of pocket). I have two hydratation bags. 2 liter bag with dimensinos 6.7 x 15.1 In , and 3 liters bag with dimensinos 7.9 x 14.8 In. Are those hydratation bags compatible ?

Is the lid/brain of this pack waterproof (or at least highly water resistant)? Trying to figure out if I should put the contents of the lid in a dry sack or not

Ultra fabric is almost functionally waterproof. Is the "bag" of this pack (where you'd store your sleeping bag, clothes, etc.) made entirely of Ultra fabric? Would the "bag" of this pack be much more "water resistant" than your all-robic nylon packs?

How/Where do you put a hydration bladder in this backpack? I can't seem to figure out where it should go. Pictures would be appreciated!
