Mostly great, need to redesign the straps

Overall nice bag. Plenty of storage. Comfortable to wear even for long distances. Unfortunately the top wont strap shut unless absolutely beyond full. Kind of a shame to walk around with the lid part flapping around.

Come on, fix the clasp!

Yes, the clasp that is supposed to secure the top lid does NOT work. Super annoying. Other than that it's a solid pack. It is shocking that clasp system ever made it to production.

Would buy again

A top of the line backpack. We’ve put it through the test, foraging for mushrooms in the PNW (very rainy and always wet). The bag kept all contents nice and dry.

top hook flaw, otherwise great technical features

great backpack BUT major design flaw in the hook that closes the brain and top of the backpack. It does not stay done up no matter how tight you pull the strap or how full or empty the backpack is. With the hook continually opening, the other technical features of this backpack are useless.

Good pack, terrible brain closure system

I purchased this bag after trying and returning both the Exped 25 and the ULA dragonfly. I wanted a waterproof or water resistant day pack for hiking, traveling, and carrying my work stuff (although I didn't need it to be "professional" for that purpose). I like how the scrambler has a brain, and pockets, is water bladder compatible, and clearly cleverly designed hooks for organizing gear if you're climbing or otherwise using carabiners. I have not tried it in the rain yet, but it appears to be made of material that can withstand it. I got the version with the colorful straps, and I like the pop of color against the black. The brain is removable and you can just use the little flap instead. HOWEVER, the clasp used to hook either the flap or the brain is an almost fatal design flaw. It does not stay hooked, no matter how tightly you pull it or how full or empty your pack is. So the brain unhooks and flops about against your head as you walk if there's any amount of stuff in it. It's infuriating, and I still can't wrap my head around why it was designed this way. However, I do like this pack otherwise. I purchased a sea to summit field repair buckle (.75 inch) and replaced the stupid little clasp with a proper snapping buckle that solved the problem. I hope Mountain Hardwear listens to the reviews (I'm not the only one) and fixes this in future incarnations.

Look no further! The perfect climbing bag has arrived!!

I love this bag so much! Not only has it been the perfect piece of gear to organize all my climbing equipment, but it also looks amazing! I’ve gotten so many compliments on my new Scrambler and I couldn’t be happier that I purchased it. All of the organizational hooks and gear straps really make this my new go to climbing bag.

Fantastic Pack

This is a fantastically designed pack. The material is very thick, durable, and water resistant. I’ve used this pack for half-day, full day, and overnight winter mountaineering objectives. The main compartment is very easy to pack and organize, and the exterior straps are extremely well designed to secure gear to the outside. This bag has more than held up to beatings on harsh trips in harsh conditions. The top pouch design makes it secure when on, but easy to remove as well. The built-in cover flap makes using the bag without the top pouch just as solid. The straps and hook loop take a second to get used to using while wearing thick gloves, but once you get the hang of it they work well. Great pack for mountaineering, rock climbing, and multi-use day pack. And to top it all off, it looks awesome.
