The Scrambler RT 35 rucksack is a completely waterproof, tough and durable roll-top pack with plenty of great features. Ideal for mountain and crag use.

Mountain Hardwear says:

We took everything that’s made our Scrambler rucksack a longtime favorite of rock climbers, hikers and skiers — top loading, purpose-built design, comfortable suspension — and created a new series of packs that go even further. The Scrambler RT 35L with OutDry® is designed for any journey where you could use roll-top, waterproof construction to keep your gear extra safe and extra dry.

The scrambler RT 35 is a really well constructed pack that offers a huge bonus of keeping everything inside fully waterproof. The pack has one main inner section which you can pack a surprisingly amount of kit, one large stretch front pocket and one separate hydration sleeve for storing a bladder (if you choose to use one). Unlike the scrambler 30 this pack has a roll top closure for extra water protection with two plastic buckles - not as fiddly as the metal hook but also not as durable. 

The shoulder straps and back system are nicely padded and really comfortable. This pack also has a padded waist strap which has two small zip pockets for storing energy bars or anything else you want to get at fast. The pack has plenty of other great features including compression straps, side pockets and carry loops for holding ice axes and trekking poles. Because the fabric is heavy duty it does make the rucksack heavier than others of its size but I don’t think you can have good waterproofing without a bit of extra weight so the compromise is good.

Simple and Versatile

I recently purchased the scrambler RT 35 after a long search for a new pack and it has lived up to my expectations. It has everything i need and nothing else.
I wanted a light weight pack primarily for hiking and also for larger mountain biking missions where my hydration pack was too small. After going more lightweight with my hiking gear this bag is perfect. It weighs very little considering how tough it feels. It has a clean and compact profile yet fits a lot more than you would think. Here in NZ we have a large backcountry hut network so with no need to carry a tent i can fit a weeks worth of supplies, or with a shelter enough for a few days hiking. The single compartment and lack of zips and excess straps actually makes accessing my pack easier and faster than my last pack. I am now sold on roll tops, you can easily adjust to how full the pack is. So far the waterproofness works and it rains a lot here. I no longer use a pack liner, and the simple exterior has no need for a pack cover, further adding to the simplicity and low weight. The pack doesn’t transfer any weight to the hips but for me this is a plus, as long as i keep my gear weight down it is super comfortable / unnoticeable on my shoulders and it frees my hips for better movement in technical terrain. The lack of frame also means the pack lies flat for storage and travel. The material feels durable and was fine after hours of scraping through branches and bushes. The outer mesh pockets don’t get caught but are still large enough to be useful. I use flexible water pouches instead of bottles and they fit really well on the sides. If you use a hydration bladder in the back sleeve the pack can’t be too full or poorly packed as the back panel will get out of shape but i find this is the case with most packs. The only negative i have is the zip pockets of the waist/hip belt. They are completely useless. They need to be much larger or not have them at all making the pack completely zip free! But don’t let that put you off what is a seriously useful and functional pack.
