Ozonic™ 70 OutDry® Backpack is rated 4.9 out of 5 by 7.
Rated 5 out of 5 by from Great Pack for long trips I wore my the Ozonic 70 Outdry pack on 50 mile backcountry hikes through the Pasayten Wilderness and Glacier National Park. The pack was comfortable and very waterproof without having to worry about bringing a pack cover. During a rainstorm I was not sure whether I should have brought a cover. I was ecstatic when I opened my pack after the storm passed to find my down bag, extra clothes and food was all dry. I have owned numerous backpacks made by several different manufacturers but this pack is definitely superior to anything I have ever worn. Great job Mountain Hardware

Rated 5 out of 5 by from This is the pack you've been looking for. I had a soft search going for several months for a good 70L pack. I finally decided on this one and I'm very satisfied with my purchase. The waterproofing is an awesome feature, and the pack itself feels sooo much lighter on my back at 45lbs than my last pack felt at 35lbs. Having the removeable top is another great feature, because you don't always need the full 70L. I was hesitant to buy a pack without a hydration sleeve, because I drink a ton of water and I love the convenience of an over-the-shoulder hose. But once I received the pack I found that the side pockets were actually a perfect size for my 3L hydro bladder. I can fit one in each side pocket and carry as much water as I need. The only problem I have with this pack is the carrying loop. It seems very small and pretty flimsy when compared with everything else on the pack. It's also in a pretty inconvenient location--it really can't even be used if you have the pack cover attached and loaded. For a 70L pack, I would expect there to be more thought put into the carrying loop. However, everything else about this pack is spot-on.

Rated 5 out of 5 by from Great pack!!! I was originally planning to get a woman's pack for myself, however ended up getting this unisex instead. The pack is extremely comfortable and you can easily adjust the straps to make it fit and feel very well! Plus, although that it's a 70L pack, you can easily make it much smaller in volume. I definitely don't see any issues also using this pack for traveling purposes. All-in-all, great pack and highly recommend :)

Rated 5 out of 5 by from The perfect pack for an extended trip I originally ordered the South Col 70 (mountaineering pack) but quickly realized I needed more padding for an extended backpacking trip, the Ozonic 70 provided and offered more than expected. This was the first time I didn't have to worry about bringing along a rain cover or a small daypack, the Ozonic provided both. I was slightly disappointed with the lack of front access to the pack, but knowing I could keep walking when the rain, hail or snow comes without digging out a rain cover made up for it two fold. My most recent 8 day excursion into the Yosemite high country threw every source of moisture at my pack and everything stayed bone dry, including my expensive camera equipment. On a 'rest day' I was able to convert the removeable pack cover and the removable hip belt to make a fanny/day pack that was able to hold snacks, water and extra clothing so I could race up to tag a nearby summit. The freedom of not having a bulky pack yet still having a reliable storage system while travelling light was incredible, I would highly recommend testing the daypack situation out before your next trip. Overall I love this pack, the fit on the s/m was perfect for my 5 foot 6 frame and the padding was enough to keep a majority of the hip pains down to a minimum.

Rated 4 out of 5 by from ozonic 70 Loved the pack, easy to open and close, well thought out pockets and attachment points. Pretty light weight and of course it is waterproof! One major flaw and that is that the poles in the frame where they come down behind the waist belt can be felt through the padding. So it needs more padding there for sure. Also I wish the women's came in a 70 L at least or an 80L even, I had to get a men's.

Rated 5 out of 5 by from Great Pack I received this new backpack a week ago and have some initial thoughts. 1. The construction seems excellent. It is made with a 100% waterproof material and durable ripstop 2. The padding on this pack is better then I expected. They really put some thought as to where to put cushioning on the straps and the back panel. The waist belt is comfy as well. The stretchy mesh pockets on the waist belt easily fit an Iphone 6 with a case which is a nice touch. 3. For those looking for more organization, this is not the pack for you. The main compartment is basically like a giant dry bag, roll-top and all. I use packing cubes, so this is not an issue for me. The water bottle pockets are huge and the lid can be removed and carried wallaby-style. 4. Overall a solid purchase that I am very pleased with.
