Rated 5 out of 5 by from Great packFeels lighter than it is when fully loaded, as MR packs usually do. The adjustability is great which also helps make the pack so comfortable. Perfect pack for the weight conscious backpacker not looking to go ultralight, it really shines between 20-35 lbs load carry and can easily handle loads up to at least 45 pounds. And the price is at least as good as any of the competitors.

Rated 5 out of 5 by from Awesome backpackVery comfortable pack, lightweight but still able to handle a good load. I particularly appreciate the fact it has a brain. It’s not commun for lightweight packs.

Rated 4 out of 5 by from Carries wellI have a Terraframe 65 that has served me well for quite a few years but with age and wisdom I decided I wanted something lighter. I was researching ultralight packs when I saw a YouTube review of the Radix 57 and I decided to buy it in February. I have around a 50 late winter miles on it so far. The build quality is good with the expected tradeoffs of a lightweight product. I don’t like the finicky small buckles that are tough to use with gloves on but I’ll get used to them I suppose. The waist belt is comfortable with adequate sized pockets. The shoulder straps are comfortable. The yoke adjusts easily. The only real miss is the side pocket design. It is difficult to get a water bottle in and out of them while wearing the pack. It becomes impossible [for me at least) while winter backpacking when I wear a bulkier jacket and gloves. I am 6 ft/200 lbs with decent to good flexibility in my shoulders and torso but the location, angle and top hem of the pockets just aren’t conducive for easy access of a water bottle while wearing the pack. Again, this could just be me. Your experience may be different. I like the pack overall, more so when I use a water bladder instead of bottles. It’s just that using a water bladder works against being able to have a lighter load.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Lightweight and StrongPack is lightweight and durable so far. Ive only used it a few times with a full loadout. ( including a 10lb tent, sleeping bag, sleeping pad, food and water.)

Rated 5 out of 5 by from Love it!After trying out many different packs (Osprey Atmos AG 65, Osprey Aether 65, Gregory Baltoro 65, Terraframe 3-Zip 50), the Radix 57 was the one that fit and felt the best for my body. Some people reported that the padding isn't enough for the Radix but for me, it's just perfect. I didn't like the thick padding like on the Atmos AG, etc.. it just felt "too much". The Radix also has just the perfect amount of loops and whatnot while still maintaining a "minimal" feel to it.

Rated 4 out of 5 by from Great bag design, don’t love the hipbeltI was previously using a Coulee 50, and love everything about it other than the size being a touch too small. Radix 57 seemed like the perfect upgrade. Turns out it has WAY more room, since that 57 liters doesn’t include the enormous outer pockets. Pros:1. Pocket layout is great. Good amount of space in the brain, the tiny key holder pocket is perfect and includes a lanyard, and the shove-it pockets are spacious yet cinch down. 2. Light enough to make a great summit pack too. And speaking of that, there is plenty of clearance to be able to look up while scrambling/climbing. 3. Just fits a bear vault 450 sideways in the bottom. Awesome!4. Fabric is very durable especially considering g the light weight. Cons:1. The hip belt is tiny and weak sauce. The buckles are microscopic and do not have enough friction to keep the belt from loosening up. The pads are a okay but this loosening almost had me ditch the pack, until I decided to throw on my coulee 50 hip belt. Problem solved! If this affects you reach out to MR for one of those belts. Bonus is it’s a bit bigger overall and distributes weight better. 2. Main bag is very tall, which isn’t bad, but it needs a second drawstring 8 inches or so down from the top. Like older, bigger MR packs. Loads that sit above the upper compression strap get a bit floppy. This is pretty nitpicky though and shouldn’t stop anyone from buying this. Overall a great pack and I would recommend it, especially considering there’s a solution if the hip belt isn’t working out.
