An awesome jacket

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Small

This jacket is awesome! I bought it for hiking down here in Costa Rica, thinking about the raining season ahead. Although it hasn't received any showers yet, I did put it to test: under direct running water, it was magical to see the water being nicely dispersed! I took it to a hiking trip to Cerro Pelado, Guanacaste, Costa Rica, that place is beautiful yet very windy, more like blazing windy. Up there on the hills, the wind was so wild that I could barely stood upright, it was crazy! So, I remembered I had brought with me this jacket, I put it on, along with the Backcountry branded Buff to cover my face, and it was just a perfect combination to calm my nerves and to stop the chilling wind.
I'm 5.9 and I went for the small one, perfect fit (not baggy at all). Fully recommended. (If you see the jacket a little bit to puffed up in the picture, it's because of the crazy wind!)

An awesome jacket

Lightweight and Stretchy

  • Fit: True to size
  • Size Bought: Large

I like this jacket more each time I wear it! I've worn the jacket in the snow and rain and I stayed dry every time. It has a good amount of stretch to it and have even worn it over the top of my puffiest puffy jacket, though I looked a bit like the Michelin man haha. I wanted to be able to wear a couple layers underneath it so I ordered the Large size and it fits exactly as I had hoped. I'm 6'1", 190 lbs, 42" chest and 34" waist to give you a reference point. It has small pit zips under the arms that provide some ventilation and decent sized chest and side pockets with zippered closures. I bought it with trail running, hiking, and ski touring in mind. For my winter morning runs, all I need is a shirt underneath and I'll stay plenty warm. For me, 35-40 degrees on sunny days will be a little too warm for this jacket for a high aerobic activity like trail running, but it would be great for hiking and touring in those same conditions. Let me know if you have any questions : )

Stretchy, Breathable, Dry.

There's really no mystery to this jacket. It performs as advertised and expected with flying colors. The stretchiness factor is definitely something you'll notice when taking it into the wild. Your range of mobility is the key to hiking and adventuring. Another notable element is the weight: this jacket is extremely lightweight and easily packable for any trip.

The Ozonic isn't exactly the piece you'd want in a torrential downpour, but this is an outstanding jacket for taking through wet climates and light to moderate rain. Overall, you're getting a high quality, reliable jacket that performs beyond expectations.

Good outer layer

    Got caught in some snow while hiking and this jacket did a great job as an outer shell. However, I don’t know if it’s completely waterproof because when I got back to the truck and took it off it seemed to be a little wet on the inside. If you’ve got other layers underneath it shouldn’t be a problem though.

    Wear it even when it's not raining!

    I used this shell on a three week long expedition across Iceland. We had rain in the forecast nearly every day, so I got to know the jacket real quick. I've had my fair share of shells over the years, but I feel the breathability of this one outperforms all that I've used.



    Now the stretch. I didn't know how much better a shell could be till I experienced stretch for the first time. If you're considering stretch, just do it, you'll never go back.



    I am 6'4", 200lbs and got a large, perhaps could have gone with an XL for the arm length, but sleeves being a bit on the short side is normal for me.

    Wear it even when it's not raining!

    Dad loves it!

    I got this as a gift for my dad, who lives in the Seattle area and needed a rain jacket upgrade. This one is a great stretchy material that moves well with you, is comfortable, breathes well, and isn't as noisy as a standard shell! He has raved about it the past few months, and it has been standing up well for his commuting and hiking. Highly recommend!

    Best All Around Jacket

    I have had this jacket for around a year now and I love it. It is the best fall jacket I own. It isnt super heavy and isnt too light but provides the just right amount of warmth. It is also wind resistant which is a great plus. Would totally recomend this jacket.

    One of my favorites!

    Do you ever get that piece of gear that you just say to yourself "they did this right!" This is that piece. I don't have anything bad to say about this jacket. I love the long sleeves, weight, fully taped seams, comfortable fabric, stretchy, and style. Everything about this jacket is done right. Even the vents under the arms are perfect, they aren't long enough to actually run through your pit, which means you don't have to feel that awkward zipper all day long. I highly recommend this jacket.

    One of my favorites!

    Great Mobility!

    • Size Bought: Medium

    This jacket has a great relaxed fit and incredible mobility with a fabric that has some good stretch to it. While many would aptly use this piece for hiking or climbing due to the increased range of motion, I like to swim against the current a bit. So I decided to use it on the golf course when we ran into a bit of weather. It held up great and didn't impede my swing at all! It was a light rain but not a single drop had soaked into the jacket. It beaded up and rolled right off. In addition, the state orange color really pops out there on the golf course.. No one is gonna miss you in this thing. So you'll never have to worry about anyone hitting into you. Overall, awesome piece, great fit!

    Lightweight, packable, stretchy goodness

    I took this shell through a 90 mile traverse of the Wind River High Route. This year the Winds had a 150% snow pack, meaning that a decent portion of the route was glissading and traversing snow fields. This, along with the standard 1pm thunderstorm every day made for some wet conditions. This jacket performed very well for those flash storms, kept me warm on the windy ridges, and was only 9 oz so it didn't weigh me down.

    This isn't the lightest weight shell like the OR Helium at 6 oz, but the extra pockets, 2.5l membrane, and stretch mobility are worth an extra 3 oz. This thing still stuffs inside its pocket and packs down very small.

    Absolutely awesome

    Super stretchy and dynamic, breathable and waterproof. I use it for multi pitch climbing and absolutely love it. It packs down so small and really helps keep you warm on a brisk morning, in the shade, or when your a few pitches up and the wind is hitting you on a hanging belay.

    I recently used it for whit water rafting and it fit in the pocket of my PFD. I was jumping in and swimming freezing cold rapids a bunch, and even though it was completely submerged, I pulled it out of my pocket and it dried in 5 minutes and help me stay warm as the wind picked up.

    I'm 6'2" 165 lbs
    I'm pretty tall and skinny but have broad climbers shoulders a size medium fits and works well for climbing, but size large is a better fit and would accommodate layers better.

    Stretchy Comfort

    This jacket is great, the material is top notch. I took this on a long weekend to Steamboat to put some use on the river with. We had some overcast weather and a bit of chilly weather and this jacket held right up.

    The fit on the jacket is very close to an alpine fit, meaning someone who is a bit slimmer with longer arms would find a good fit to this style of jacket

    Love it!

    it's light weight, water proof and has great style. Does the job and holds up well with its great quality.

    So this is my second rain jacket from MH and I may never buy another brand! I beat up the first so bad that the lining started to shred, was a bit concerned, but I wanted to try MH again as the fit was perfect. I am 73" and 205 with broad shoulders so finding a jacket that fits up top and isn't a circus tent at the waist is hard. The Ozonic fits really well and moves with me when I am out on the town or hauling a ruck around the world. I love the stretchy material and it moves quietly not the plastic on plastic sound of other rain jackets. No problems with the rain but I haven't seen a big storm yet. The one negative, I was upset with the color at first. I got my hands on the Thunderhead Grey, on 50% sale at the time, but it isn't really grey at all. More of a muted OD Green. Thunder clouds tend to be more grey in my neck of the woods so that was a bit misleading. Overall the color is decent and I am happy.

    Waterproof and awesome

    I purchased this jacket for raining days and / or chilly days to take the edge off. When I first got it i was dying to test how water proof it was. There was no rain in the forecast so I stuck the arm under the kitchen faucet and it rolled off like water on a duck's back. I know it sounds lame but you cant just wait until it rains to find out. Since my scientific test I've worn it in the rain with the same result. Just a little shake and the water rolls off.
    The best part is the comfort. It's stretchy which makes me never want to take it off. Overall awesome. I like jackets a little on the fitted side so I purchased a small. I'm 5-9, 150#. I dont wear sweatshirts under it. If I planned to wear a sweatshirt under it I'd probably get a medium.

    Stretchy goodness

    I am 5'11" and 195lbs. This is a size L jacket. Haven't used this specific jacket out in the elements. Would be ideal for hiking/backpacking. It also looks nice and can be casually worn around. If you have any questions about the fit or use of this jacket or any other Mountain Hardwear product, please let me know!

    Stretchy goodness

    Thank you for the visual, helps much more!

    Hey Patrick! I'm 1.83 cm and weigh 80 kg = 176 lb with a fit complexion (more slim than bulky).
    I was thinking on getting M, but seeing your picture maybe L could work. I don't tend to wear things loose, that's why I was thinking M.
    Please let me know what size you think would work best.

    cool lightweight jacket

    • Familiarity: I've used it once or twice and have initial impressions

    I love how the jacket looks, and it's pretty small & ligthweight, so I can always carry it in my backpack. Regarding waterproof, so far I've test it in small rains and it has hold up pretty well. Need to test it when it's pouring.
    I ordered a M, which is my usual size in everything and it fit perfect.

    Lightweight and holds up

    This is a great rain jacket that is both lightweight and breathable given the softshell material.

    Great jacket. Waterproof and lightweight. Large fits well enough on me, maybe could have went down to a medium but a large gives me room to layer underneath it.

    I picked up this jacket before my most recent trip to guide skiing in Patagonia. I wanted a lightweight/packable/breathable shell for light-duty ski touring and for casual jaunts in the mountains. I was impressed by the comfort and ability to fit multiple layers underneath. It is a joy to wear for long skins when the sun is shining and you need a bit of a wind breaker. I also found it to be quite good in light precip, although don't count on it to sustain a downpour, no gore-tex here. I would recommend this to mountain folks also looking for something to wear around town when the weather isn't too cold.
