Great Sack (Review by deMag)

This bag went to the Great Barrier Reef, and a trip Down Under, packing clothes and towels and electronics and gear for 3 of us. It can hold a lot or a little, as it folds in and tucks nicely no matter how much we stuffed into it. Only a 3 week holiday with daily use, but, I would tell anyone that is it a great item. It also folded up flat easily when empty and did not add weight to our carry on bags.

Excellent all purpose pack (Review by Schaefer)

I bought this bag to use as a mini pack liner inside my 75L to keep my important things dry as I dirt bagged across Europe. I learned that it also makes a great compression sack inside the main bag as well. I ended up using it frequently as my cragging pack so I could leave the heavy bag stashed somewhere. It was my go to for shorter trips and excursions that would only last up to a week where I didn't want to carry the 75L. I have used this pack as an ice climbing bag and have been very impressed with its ability to carry a full load of ice gear and tools. I have also used it as a dry bag for slot canyons and river trips, it serves this purpose great too. It works great as a fast and light alpine bag, as long as you're staying light enough not to need something with structure and support. It's my go to for car camping and weekend trips. It compresses down really well, it carries just as good at 12L as it does at 31L. I have beat this thing and it is bombproof. Only a few things have hurt it. First, an ice screw that was poorly packed stabbed a hole in the side (obviously my fault, not the bag), I patched it with gore-tex and is once again waterproof. Second, the rear mesh has been semi shredded by cramming it through slot canyons. Third, the shoulder straps started to separate from the pack pretty fast and I thought they were going to tear off, that was over two years ago and they still look fine. The only downside of this bag is that it doesn't breath at all, so it gets nice and sweaty on your back pretty fast. That's to be expected with a dry bag so it's not a big deal to me, I'd never take it on a hot summer hike anyway. I love this bag for the same reason I love my trusty Nalgene bottle, I know that no matter what happens to it, I can count on it. BOMBPROOF, I highly recommend it.

great for what i use it for (Review by tyson)

i use this bag to carry my wetsuits when going surfing. it easily fits my 5.4.3, boots, gloves, towel and flipflops. i use the outside mesh pocket for wax and snacks. after surfing i just stuff all my wet stuff in the bag, seal it up and it keeps my car dry. no leaks.
this bag is great for what i use it for.
i would love to see one built that is twice as wide, 50L-60L. with a wet side and dry side. so that way i could carry wetsuits and all my stuff for a few days at the ocean. keep my clothes dry and i can carry wet stuff out til i get to were i can dry it. that way i could carry one backpack, which is my preferred way to carry things.
