Scrambler™ Roll Top 35 OutDry® Backpack is rated 4.4 out of 5 by 13.
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.

Rated 5 out of 5 by from In love with this! I searched high and low for a dry bag that you could wear like a backpack and is comfortable too. This is it! You do need it packed at least 3/4 of the way full for the top to close normal but that's fine for me. I've dunked it in water and had it sprayed with water on a boat all day and it never got a drop of water inside! The only thing I would change is adding an inside compartment. Right now it's just one big area and it would be nice to be able to separate some of my smaller things into a pocket on the inside.

Rated 4 out of 5 by from Simple Pack done extremely well! I original purchased the Scrambler RT 35 OutDry as a day bag for canoeing, snowshoeing and as a city bag for traveling. Picked it based on the simple roll top entry, the water proofing and how plain/low key it looks for traveling in cities. Definitely a sleeper of a bag and it's surprised me with how well thought out it is. It has quickly replaced my 30L external framed hiking pack for day trips and light overnight camps. If you are smart about packing a rucksack style bag and your sleep system fits into the space you can get a lot out of this little bag. Pros: -Roll top with no brain makes for quick in and out for larger items like a camera or water filter. -Very sturdy construction. -Large mesh side and front pockets provide good room for water bottles, bear banger kits, rain gear and such. -Hidden daisy chains well designed and sturdy. Great if you want to lace up extra gear to the outside. -External water bladder entry with drainage. -Hip belt and gear loops can be stashed/reversed inside the bag for light hikes, bike rides or airplanes. -Bag compresses down well for smaller loads or packs down flat to bring along as a day bag on larger, longer trips. -Wide flat shoulder straps fit myself very well and have very good range of movement. -"Alpine style"/"portage pack" harness has great balance for up and down scrambling and hiking. -Waterproof, no need for extra liners or dry bags. Awesome if you pack down filled gear. -Light! without being ridiculous or sacrificing sturdiness. -Less is more. Cons: -This is a light 35L pack with an "alpine style"/"portage pack" harness. It is not going to save you if you over pack. External frames, suspension and full hip belts are more suited to multi-day trips and heavier loads then this bag. -If you are more concerned about pockets and dividers when it comes to packing there are far better options out there for you. This one really is just one big pocket. -Ventilation seems to be the trade off for a lot of the bags better qualities. It's very far from the worst (especially for a waterproof bag) but really far from the best. Simple pack done extremely well. Minimalist without being mental about it. Solid bag!

Rated 5 out of 5 by from Great adventure pack I use this pack for Nordic Skating and it is the perfect size to hold all of my safety equipment, food, and any extra layers for a day trip. I really like the waist belt, it helps keep the pack in place while skating. So far it has proved waterproof and durable. I feel that the top is very secure, even without the pack being full. It does have the capabilities of being scrunched down smaller with the side straps, so that helps keep the top tight too. It acts like a big pack, but looks like a small pack. The pocket for a water bladder is really nice. I like that it is its own pocket. The stretchy mesh front part is great for stuffing miscellaneous small items in, like snacks, gloves, or similar. The little pocket on the waist belt has been nice for other small, important items, like keys or camera.

Rated 5 out of 5 by from Great multi-purpose pack What can I say, this pack is great! I used this for several hours kayaking, and the pack got absolutely soaked on the outside. I was a little nervous to open it up afterwards, but everything inside was completely dry. Not a drop of moisture. The outside material does seem to have a very mild DWR finish, but I could be wrong. Either way, the outside material wet out after about 20 minutes of being splashed on the lake. The good news: it dried within minutes of being off the water. I have to disagree with a previous review stating that the roll top has no actual waterproofing. It appears to have the OutDry material laminated throughout the bag, from bottom to top. I read reviews complaining about the small hip belt pockets. I did not find these to be an issue. I was able to cram energy gels, bars, ect in them with no problem. Are they huge? No. Are they functional? Yes! There is a thin Velcro attachment point for the hydration bladder. I noticed several times if you aren't careful when you pick up the bag, you can stress this Velcro point and it will open up, causing your hydration bladder to fall to the bottom of its compartment. Not a huge deal, just something I needed to be aware of. Once I paid a little more attention to how I was handling the bag, this was not an issue. I am 6'4", 190 lbs and this pack fits a bit small. However, after some adjustment, I was able to get a comfortable fit with the hip belts securing where they should - top of hips. Overall, this bag is awesome. Looking forward to it being my new go-to bag for short trips to the back country.
