Why We Like The Scrambler 35L Backpack

The Mountain Hardwear Scrambler 35L Backpack is designed to assist us with steep, rocky approaches to our favorite crags—to scramble, if you will. This do-it-all climbing pack is made from a durable fabric that's both lightweight and waterproof, delivering protection that won't tire you out on a long hike, and it features plenty of room for all your climbing gear.

The Scrambler features a contoured backpanel that's ventilated to keep you comfortable on warm, sunny days, with a lightweight frame sheet for additional support. The floating lid and sternum strap can be removed if you want to travel light—you simply cinch down the top after that to secure your gear—and its stand-up design makes it easy to post up once you get to your goal.

Just what I was looking for!

Perfect size for a day of climbing. Simple, light and durable. Not a bunch of unnecessary pockets and zippers. Separate compartment on top for snacks, keys, etc. I like the separate pocket inside for my three liter water bladder.

front closure

excellent quality bag. my only complaint is the front hook closure. it tends to open on its own unless the bag is completely full. otherwise, I'd give it 5 stars

Almost perfect

Everything a technical pack needs and durable fabric. The only feature i have not enjoyed is the single center strap to secure the lid. Like similar packs, its difficult to use with a helmet mounted on. This scrambler securs the strap half way up the pack helps a bit.

Set up for ski touring

I purchased the Scramler 35 to replace my well-used ski touring pack. It is light but the fabric seems durable. I added a piece of 1" webbing (through the back) so that the waist belt is continuous webbing to reduce stress on belt-pack stitching and lower side straps for hauling skis. Loving the pack so far!

Top lid hook comes off, and need bright colors.

The hook that holds down the top lid would be better if it was a clip. When it's loose or with out tension it comes unhooked. I would have liked a color other than white or black. I like yellow and orange. Helps stay visible. The white blends in with snow, black with rocks. Thanks for reading. Have a Merry Christmas. Thanks for making great gear.

Excellent design, one small idea for improvement

I bought both the 25 and 35L versions of this. IMO the 35L is the better choice as it’s only slightly heavier with a lot more carry capacity and has identical features. It’s not the lightest pack I own but very affordable for the weight and all around multi-purpose as the description states. I use it without the lid in warm seasons to make it lighter, fill the lid with gloves and hat in the cold. If the overall weight ever got to be bothersome I would cut off the features I use the least (interior and exterior gear rack, maybe one of the haul loops) and will continue to choose this pack for durability if I know it’s going to get beat up, dragged, hauled, dropped, loaded up with skis or rope, climbing rack, things that would severely tax or destroy more ultralight and expensive bags. The only small thing I don’t like as another review mentioned, the seams inside are not taped but instead are sewn. This allows water to wick up inside, in my case only from sitting it down in snow. I understand this construction probably keeps the price low which is great, and it’s no problem to use a nyoflume or trash bag liner for snow days. The pack fabric itself is bomber and very water repellent. I plan to add some seam grip to the outside bottom and see if that helps. If future iterations of Scrambler were welded and taped (at least on the bottom) it would be five stars in my eyes. Thanks MHW!

Top pocket zipper snags

The zipper on the very top pocket is constantly snagging the fabric alongside the zipper. There is something about the construction where the fabric folds over the zipper and is just always in the way. I have had this bag less than two weeks and I can already see the fabric starting to fray a little where it gets caught in the zipper. And these bags aren't cheap. :( Yesterday I tried to gently iron the seam where the fabric and zipper connect to see if that can hold it out of the way, so we'll see if that helps. Otherwise, it is spacious, sturdy, and comfortable. I live in a rainy city so I like using it to carry around groceries, and if my computer is inside I feel secure.

This is a good short hiking backpack. The protection of the X-pac material itself makes this pack hardwearing and waterproof. Most importantly, the pack is lightweight, which is my favorite thing about it!

Too Small

Too Small. looks much larger in pics, still a good bag, but not as big as it looks. the 25 is even smaller (obviously).

not quite right

not the pack for me. weird material, and the hook that closes the lid to the pack body is not a good design. i was looking for something to replace my OUP rainshadow 26, and this was not it. great company and return was hassle-free.
