Scrambler™ Roll Top 35 OutDry® Backpack is rated 4.4 out of 5 by 17.
Rated 5 out of 5 by from Great for travel and several day outings I recently took this pack with me down to the Huasteca Potosina area in Mexico. All my gear for a week-long excursion that involved torrential rainfall, river crossings, coupled with the hot and humid sunny days, managed to stay dry and secure throughout. I didn't have any issues with leaks as the roll down top effectively seals the solo opening. I'll definitely be using this as my go-to travel pack as it fits under the airplane seat with 1/3 of the top invading your leg space fully loaded, albeit with enough space on either side of the pack for your feet to rest comfortably.

Rated 5 out of 5 by from Best cycle commuter backpack! Best cycle commuter backpack for a rainy day! Completely waterproof and the orange colour is great for visibility. Can't wait to try it in the mountains! (This review was collected as part of a promotion.)

Rated 5 out of 5 by from Solid Piece of Gear Comfy on a hike, tough when getting scraped against the rocks, fits everything for a day hike in variable temps/ weather. Haven't tested it in pouring rain yet, but look forward to that!

Rated 2 out of 5 by from Very Strange Pack I bought this pack online sight unseen. My only reservation was I wanted horizontal straps across the middle to strap snow shoes too. There are actually gear loops running up inside the seams so this can actually be done easily, which I am very happy about. However, upon receiving the pack, I noticed a very strange configuration. The back padding is actually separated from the main pack compartment at the top side where the shoulder straps come in. The back padding is connected to the main compartment on both sides and on the bottom, but not at the top. This creates a chasm between the back padding and the main pack compartment, running all the way down the pack to where the base of the back padding is connected to the main compartment. This seams like an ideal place for snow, water, dirt, etc, to accumulate and possibly seep into the main pack compartment. There is a Velcro strap inside this chasm, I cannot figure out what it's for. Maybe to somehow seal this compartment? Maybe I am doing something wrong? It seems like a very strange configuration and a serious potential for water to get in and I can't figure out why it's there. Otherwise, great pack, but that one configuration is enough to impact the main function of the pack, which is to keep things dry. I am considering returning the pack because of this.

Rated 5 out of 5 by from Scrambler rolltop 35 Great Bag! This bag has so many great features for 35 liters. The roll top makes it easy to get into the bag and eliminates the trouble with zipper and water leaking through them. Its fast to get into and the roll top is so easy to use. The OutDry fabric is strong and durable and 100% waterproof. No rain covers to mess around with. The straps are comfortable even with a big load. Lots of pockets with easy access. Overall an awesome bag! I'd highly recommend it. (This review was collected as part of a promotion.)

Rated 4 out of 5 by from A 35 liter pack that can do it all. I wanted a backpack that I could use on extended day hikes in southeast Alaska. I work in Skagway, Alaska during the summers. I wanted a waterproof backpack so I didn't have to worry about about my gear and/or stopping to cover my bag. The first thing I noticed was the quality of the construction of the pack. I know I could beat this up. SE AK is a pack destroying land! Almost every hike you're going to have to deal with granite, overgrowth, water, and branches wanting to wreck havoc on your pack. The Scrambler RT was never scared or intimidated. It handled ice caves, scree and talus fields, and bush wacking like a backpack made out of 2x4's. I was trekking through a talus field and slipped backwards. I fell on a rock of course and slid a bit. When I slid I heard what I thought was the pack tearing. Nope, it was fine. Just a barely noticeable scratch on the pack. Seriously, this thing is tough. Right now I'm packing for an overnight hike to Clouds Rest in Yosemite. I love the large roll top opening. I am always amazed what I can fit in this thing! I would post a picture if I could of what I'm bringing. The pack carries the 22lbs I average on overnights very well. I never thought I would consider this for multiple nights, but I might? This is definitely one of my go to packs!

Rated 4 out of 5 by from Alpine assault bag! I took this bag on a multi day climb up Mount Stuarts North Ridge in the cascades this summer. It was perfect! It is the perfect size if you are willing to slim down the kit a little. Alpine climbing is always a balance between having enough kit and keeping the pack light to have a better climbing experience. This pack is perfect for a fast and light alpine assault that lasts 1-3 days! I had my MH 28 deg sleeping bag, emergency bivy, ice axe, crampons, dry food for 2.5 days, 2.5 liters water, jackets, alpine trad rack and few more personal essentials. Overall the pack weighed about 25 lbs and carried the weight well! Pretty comfortable over 26 miles of hiking and scrambling over miles of 3rd and 4th class terrain. With the rack out on our harnesses the pack was the perfect weight and balance for climbing 2000 feet of granite. On the harder sections we hauled the pack and it was very durable even when being dragged over sharp granite walls! No rips or tears after about 200 feet of hauling. The pack was very comfortable while climbing and felt very well balanced! The mesh pockets on the back and sides were much more durable than expected and are perfect for this type of climbing. Throwing a jacket in the mesh pocket for easy access at cold belays was perfect and offers increased internal space. The one main pocket is great for climbing and makes it easy to find everything if organized in smaller bags inside. Outdry material is very durable against crampon spikes and rough terrain.

Rated 4 out of 5 by from The Scrambler™ RT 35 Outdry® Backpack The Scrambler™ RT 35 Outdry® Backpack is a great pack for a technical summit or a long day on the river. It's a well constructed and extremely durable pack. It has plenty of room for a full day of food, water and your warm layers. It's a great bag, but I have yet to find the right niche in my activities for it. I found it a little large for your average day hike or river float. And a little small for an overnight trip. It weighs in at 1 lb, 12 oz.

Rated 5 out of 5 by from Really nice day and short-trip crag pack This bag is exactly what I needed - big enough to fit essential climbing gear for a day outing and great to be used for a short weekend trip (without climbing). Comfortable and durable, love the big mesh pocket in the front.

Rated 5 out of 5 by from Secure, light and basic I recently used this pack for an overnight in the high Sierra Nevada at Big McGee Lake. It was big enough for a small bear canister with stove and food, sleeping bag, mat, tent, rain gear and other essentials. Because it is waterproof, I didn't need a rain cover, used less stuff sacks and left it outside the tent with gear in it overnight. With the listed gear and a few other essentials, the pack weighed in at less that 20 pounds. I don't need to lose any weight either. The only thing needed for a three day with this pack is more food which would fit in the bear canister also. I like the basic aspect of a clean pack with nothing hanging off from it.
