When you don't know what the weather will bring.

When your hike starts at the crack of dawn and has to be finished with the help of headlamps, you want to bring the Mountain Hardwear Scrambler RT 40 Outdry Backpack along for the journey. Weather is unpredictable in the high mountains—one minute the sun is shining, the next the skies have turned an ominous shade of charcoal—so Mountain Hardwear equipped the Scrambler RT 40 with waterproof OutDry construction and a watertight roll-top design to keep you gear bone-dry in the face of torrential downpours.

HardWave suspension conforms to the curve of your back and distributes weight evenly for mile-after-mile comfort. A fully-padded hip belt and adjustable sternum strap stabilize the pack, and side compression straps help you manage your load. External carry loops hold ice axes or trekking poles, depending on how high you plan on climbing. An easy-access hydration sleeve (reservoir not included) allows quick on-the-go sips, and deep side pockets hold water bottles so you have a backup supply of liquid.

Does the pack carry skis? A-frame only, or diagonal too? Thanks.

Favorite climbing pack

  • Familiarity: I've put it through the wringer

I love this pack as I can throw all my gear into the top and go. It's simple and light which makes it perfect for the mountains. I use the stretchy front pocket to hold my guide book and I love how the top lid easily clips off!

Great so Far

  • Familiarity: I've used it once or twice and have initial impressions

Got a chance to take this out for the first time. 40L is a one night bag for me, but loaded up for a quick weekday overnight and was not disappointed. Enough room for the pad, bag, layers, hammock, strap, toiletries and 2 burritos. Material seems durable, the weight carried well, good compression. Did not test the Outdry tech, but seem legit.

Perfect Climbing/Mountaineering Pack

  • Familiarity: I've used it several times

The outdry technology is very real and very effective; perfect for short alpine/mountaineering outings. It also seems to add a layer of durability for summer climbing trips.

There are secret daisy loops that line each side of the outside helmet/soft compartment that I didn't anticipate. The ice-axe loops work perfectly. The hip belt pockets are not really meant to put anything firm in, but that's because it's a climbing pack and you need to tuck them back - which is a necessary feature.

Also, another feature I enjoy is being able to remove the top pocket altogether, and just rely on the roll top.

Overall, one of the better Mountain Hardwear products I've had the pleasure of working with. I purchased the Stone Green color and it's quite pleasing!

Is the brain/lid of this pack detachable?

Not Waterproof

  • Familiarity: I've used it several times

I like the bag, it's comfortable and a good design. However it isn't completely waterproof. I used it packrafting on the Thompson river in British Columbia for two days. After flipping my boat, the bag got wet. I think it would probably remain dry fit hiking, skiing, etc; but it didn't seem to work for submersion. This is likely because, unlike a dry bag, the bottom opening has no way to apply tension to cinch everything down. You simply roll it up and clip it to the side of the bag - tension status would likely have made it completely dry. May not be a big issue for dinner, but my stuff on the bottom of my bag got wet, and when something is advertised as waterproof I expect to work. Too bad, because it's a great bag otherwise.

This pack is NOT designed for complete submersion.

Bomber... Great for Climing

  • Familiarity: I've used it once or twice and have initial impressions

Bought this bag before climbing Matthes Crest in Tuolumne Meadows. 5 mile approach (navigation error made it 6 miles), followed by 2 pitches of climbing and a ridge traverse with technical sections mixed in.

What I carried:
- 3 liters of water, double rack of BD Cams 3 - .5, nuts, slings, carabiners, lockers, food, helmet, jacket.

The backpack carried the weight well felt comfortable to hike long distance and flexible enough to make some technical moves while climbing. The top pouch is nice for extra storage, and its great that you can unclip it and stow it to decrease the profile of the pack while climbing.

Two recommendations: there is no Key clip, so easy to include and provides some insurance that your not going to send your keys flying down the mountain when you pull your jacket out. Hip pockets are almost useless, very small and no stretch, dont expect to fit anything larger than chap stick in there


  • Familiarity: I've used it several times

Have to say, I am not a backpacker. I am more into fast and light. But every year, we do a long hike in Southern Utah, and this pack is perfect. I can shove a couple layers in, food, a light sleeping bag and pad, and a giant 100oz bladder in, and I am good to go. the dry bag offers the security you need when jumping in to a pool at the bottom of a slot, and the mild support frame does just enough to keep the load from digging in. Only gripe I found was with the hip pockets. When the hip straps are tight to lessen the load on your shoulders, removal of a bar or snack was a little difficult. Overall though, this is a perfect bag for a long day or a light overnight where you might have a little water to cross or a bit of rain to endure.

Double Roll-Top

    this has a roll top on both the top as well as the bottom which is really cool if you need to get access from either end. Very unique design from Mountain Hardwear.

    Fantastic pack!

      The "double roll" top and bottom make loading and unloading super easy. The fabric is bomber and the look is sleek. I've tried on both sizes...I could make either work however the S/M fit me best and still does. I'm a 19" size.
