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!

cool lightweight jacket

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

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

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

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

Versatile and Waterproof

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

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.

Versatile Comfort and Protection

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

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.

Versatile Comfort and Protection

Perfect Flex for your Treks.

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: Runs large

I got my husband one of these to take hiking on the Oregon coast. I wore the women's version, and we were both impressed with the quality of this jacket. It will keep you dry, dry, dry while helping you out with breathe-ability. The fabric has a nice elasticity about it, which allows it to move with you instead of resisting your adventurous desires. The design and fit are flattering, both in the mens' and womens' versions. If you're in-between sizes, size down unless you want to layer something thicker underneath.

Feels so great

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

It runs slightly large. This is a great shell that feels way more comfortable than a shell should. Nuff said!

Very Impressed With This Jacket

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: XL

I've used it a quite a bit and I'm extremely impressed with the quality of this jacket. The sizing is on point, I'm 6'1" 195lbs and purchased a size XL which fits me perfectly. Most of the time when I buy size XL jackets they fit me how they should in the shoulders but a little too wide in the waist. I didn't have that problem with the Stretch Ozonic Jacket and the stretchy material makes it so that when I'm reaching my arms out forward or moving around I don't feel like I'm going to break out of it.

At first I didn't believe something so light and thin could be waterproof but my initial impression was very wrong. I've worn this jacket in heavy rain and not a drop of moisture got through to my inner layers. Not to mention the breathability is top notch. I've worn this jacket on bike rides, hikes, shoveling through over a foot of snow, and I haven't found an activity that was a match for this jacket. On warmer days or when you just want a little more airflow you can unzip the armpit vents for extra ventilation. My only complaint is that it isn't very windproof, which is nothing that a good mid-layer can't fix.

Overall, I think this is the one jacket that I could use for any spring, summer or fall activity and be confident that I won't be getting wet or overheated.

If you have questions about how the Ginkgo color will look in person this photo is a good example.

Very Impressed With This Jacket

Is it just a shell? Only the membrane or any fabric in the interior?

Hey Michael - This jacket is just a shell, it is not insulated, although the interior has a basic nylon backing. Feel free to contact me directly with any additional questions.

Staying Dry in the Uintas

Second in the Family

  • Familiarity: I gave it as a gift but have feedback to share
  • Fit: True to size
  • Size Bought: M

I purchased an ozonic for myself awhile ago. I loved it so much, and my dad had an eye for it, that i got him one for fathers day! He loves his jacket as much as i did. He bikes in it, hikes in it, and goes to beer fest-ivities in it! His first experience was at a beer fest, and he came home saying "Em i was the only "dry" one there!"
Im glad you like it dad!

  • Familiarity: I've put it through the wringer

I'll start by saying that Jared Hargrave's review below does a great job talking through a few of the finer points of the jacket. I'll try and focus on a few others areas.



Fit:

I've got a ton of MHW apparel and really appreciate the change in fit for this jacket. Normally I either get a Large and have it be huge around my waist or get a Medium and have it be uber tight around my chest/shoulders. MHW added more space to the chest and shoulders on this jacket which means I can wear a Medium and have it fit perfectly for me.



Wind:

Last weekend in the Uintas a storm rolled in while we were up on the ridge and it wasn't hurricane force winds but still enough winds that I felt like the wind protection was 3.5 stars out of 5.



Stretch:

I have longer arms and with the width of my shoulders and chest (43") I normally opt for a Large but my waist is more a Medium (33") so apparel is a bit of a toss up. But with the stretch fabric I don't have any of the constrictive feeling that I get with other fabrics on jackets where if I move my arms I feel like I am going to hulk out of the jacket.



The stretch is awesome for mobility and being active. Definitely the biggest feature that I like aside from it's waterproofness.



Waterproof:

While we were on a ridge in the Uintas, a storm rolled in and it was spitting rain and I had no worries as I watched the water just roll off the jacket.



All in All:

I strongly prefer this jacket to any other rain jacket on the market because of the fit and the stretch fabric. Plus I don't get the clammy feeling like I have with other rain jackets.

Stretchy Waterproofiness

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

We have had a very wet spring so far in Utah, and I have had ample time to test the Stretch Ozonic in a downpour. So does it pass the waterproof/breathable test.

USES: Mountain Hardwear calls the Stretch Ozonic a wet-weather backpacking shell, but I mostly used it on mountain bike rides, trail runs, and walks around the park in the rain. April and May have been chilly and wet in the Wasatch, and I have been glad to have the Stretch Ozonic on hand.

WATERPROOFINESS: This shell is everything MH claims as far as keeping out the wet. At first glance, I thought there is no way this piece is waterproof, it is too flexible and light, almost like thin paper. Usually one relates waterproof shells to garbage bag, plastic feeling material. But my doubts were put to rest the first time I stepped out the door in a downpour. Water beads up on the shell and sluffs off. My under layers never saw even a hint of moisture. I was duly impressed.

BREATHABILITY: Top notch. To test that out I mountain biked and ran in the shell, but also boot packed up Suicide Chute in the Alta backcountry and skied down. It was a warm day, almost t-shirt weather. But the Stretch Ozonic breathed extremely well, especially after opening the pit zips for added air flow. So not only is this shell a good summer jacket to ward off the rain, it also doubles as a backcountry skiing layer as well.

OTHER DETAILS: What I also love about this shell is how light it is. It weighs almost nothing (9.7 oz) and packs down super small, ideal for throwing in a pack for just in case. I have been carrying it around in my mountain bike pack and on after-work hikes so I am never without an emergency waterproof layer. Plus, it looks good with a slim cut, minimal pockets and clutter, and colors that are not too crazy.

GRIPES: My only gripe is that there is not much in the way of wind protection. On that backcountry tour on Mount Superior, we were greeted with cold, ridgetop winds that cut right through the shell. After slipping on an insulated mid layer, I was fine, but know that the Stretch Ozonic will only keep the water out. Wind? Not so much. That being said, you should carry a warm mid-layer on alpine outings anyway, so brutal wind should not be a problem if you?re prepared. I consider this lack of wind-proofiness the cost of breathability.

FINAL WORD: Overall I'd say The Mountain Hardwear Stretch Ozonic Jacket is pretty much the essential waterproof/breathable shell for spring, summer and fall alpine pursuits. It will keep you dry inside and out, will not overheat, and packs away small until you need it. Do not go backpacking without one.

Hey Jared, what color did you purchase? Is the picture you posted for the Dark Compass or Azul color?

Most comfortable rain jacket ever

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

Have not put this jacket through the wringer yet, but so far I absolutely love it. I got a Large at 6'3 180 lbs and its perfect, fits slim enough but can still add plenty of layering underneath if needed. I'll get some pics up for sizing reference in time.

Pros
1. Feel. Gone are the days of the crinkle crackle swish swash with every stride in a rain jacket, the Ozonic material is absolutely amazing. It's soft, feels good next to skin, and really stretches with you as you move. Simply put it's the most comfortable shell I've ever worn.
2. Light. It might not be Ghost Whisperer 3 oz lightweight (which is only water repellant), but at sub 10 oz for a fully waterproof rain jacket the Ozonic is backpack worthy.
3. Breathable. The stretch of the fabric helps translate to a jacket that is more breathable than any typical hard rain shell. The pit zips add ventilation when needed as well.
4. Fully waterproof. Will see how it holds up over time, but to date I've had water beading off the jacket perfectly with no issues.
5. The small thing. The hood fits well, the zipper feels strong, the hand pockets are at the right point for backpack access, the chest pocket is a great touch, the drawcord works well.


Cons
1. I've had no problems with this yet, but I assume that the lightweight and stretchy Ozonic material will be more susceptible to snagging on branches and rocks and tearing than a hard shell would be. You will pretty much always sacrifice durability when you go light weight, maybe this jacket will pleasantly surprise me in this category, I'll see over time.
2. This shell is wind resistant, not wind proof. It adds some protection, but if you want to use it in cold windy conditions layer accordingly. I have a Ghost Whisperer Down Jacket to pair with it that does the job perfectly, these two together come in at 16 oz and are a perfect one two punch for shoulder season adventures.

Bottom line is if you're looking for a comfortable rain jacket that will move with you and breath well while being active you'll be hard pressed to find a better option than the Stretch Ozonic. After getting a feel for this jacket I plan on picking up the matching pants as well. At $200 it's by no means cheap, but you get what you pay for. I don't know of another rain jacket with this level of performance and comfort combined.
