    Rain never hurt anybody.

    Kiss trashbags, pack covers, and mad scrambles for cover goodbye, because there's no need to be scared of a little rain when you have your gear stashed in the Mountain Hardwear Ozonic 50 OutDry Backpack. OutDry is a three-layer waterproof and breathable membrane that's guaranteed to be watertight, so you can rest assured that your sleeping bag will be dry when you pull it out after a day of hiking through steady drizzle. Additionally, the removable top pocket is reversible, with one side providing easy access to your gear and the other side boosting the Ozonic's waterproof chops. 

    Waterproofing isn't worth much if it doesn't come in tandem with thoughtful design, but the Ozonic has it all covered. The vented Hardwave suspension is fully customizable to fit different torsos, and the shoulder straps and hip belt are interchangeable, so you can dial up the perfect fit for your body, load, and objective. Side pockets and a large front stash keep water bottles and layers easy to reach, and the trekking pole and ice axe carry systems lock your tools down when you're going hands free for a spell.

    Should not fester in no review obscurity

    • Familiarity: I've used it several times

    This is a great pack. I was looking for a couple things in a pack that I was unable to find elsewhere.

    Size: At ~50 liters this is just right for traveling light for up to a week or so, but small enough that its not overkill for the standard "overnite bagging a long approach peak". The narrow width of this pack, combined with a rather large top, allows it to grow and shrink better than other packs I've used.

    Large side pockets - I like to use water bottles, and grab them from my side pockets without taking the pack off. So many packs these days (Osprey - I'm looking at you) have side pockets that are barely big enough for a small bottle, and even thats a tight fit if you have a sleeping bag or something pushing out the bottom of the pack. This pack's side pockets are plenty big for a plastic water bottle + map, my standard setup.

    Good suspension - you are going to pay a weight penalty for this but in my opinion its worth it. My previous pack (an REI flash-50) was lighter but had flimsy suspension. Net-net, this pack feels better at the end of the day despite being a bit heavier.

    Under-the-bottom straps to hold a small tent. Many packs in this size range seem to be forgoing this anymore, but I think they work great. In an early morning when your tent is wet I don't like to shove it in the pack with the rest of my stuff, outside the pack is ideal.

    The shovel pouch is a nice place to put other wet stuff. It's not huge but plenty big for stakes and an extra layer if you wanted.

    The fabric is a little beefier than I think I need, but its nice that its waterproof. I suspect that the higher weight of the fabric is pretty much offset by not carrying a pack cover.

    The brain top comes off easily, and the pack actually functions well without it.

    All in all this is a really great pack if you are looking for a similar set of features.

    Should not fester in no review obscurity

    Hi Chris, please see my review on the Gregory Demali 75. Do you think this pack would be a better pack for me? I also like tall and narrow packs. What is the suspension like, is it really adjustable for various back lengths? And the hip belt, it looks quite flimsy.... Does it really carry weight well? I've found with ~50l packs the hip belts are rarely structured into the chassis.... More rather just puney after thoughts.... That often don't transfer weight successfully to the hips.

    Hiking Up to Lake Blanche fully loaded

    On MH's website, they list as a feature: "Main compartment top closure design allows pack to be used without the top pocket with no compromise in compression or weather protection." I bought the Direttissima 50 OutDry and, because of the way it's designed, the top pocket will droop forward if the pack isn't completely full. Then water is free to leak in through the draw string closure. Would you be able to post a picture and describe how this pack keeps water out without the top pocket?

    I love the look of this pack. I've heard mixed reports in terms of hydration compatibility. Some say there is none, others say there is a hook and a sleeve behind the adjustable torso/back panel on the outside of the bag. Can you confirm this one way or the other? Also I'm wondering if you think the advertised volume is with the top fully extended , or with it in a lower, more natural position. Any ideas? I reached out to MH directly about this but didn't get a response. Can't find it in-store anywhere to check it out. Thanks for your help.
