Women’s Mach 38™ Hybrid Jacket is rated 4.2 out of 5 by 10.
Rated 5 out of 5 by from Best Active Jacket Love this fitted jacket that I just bought it is super functional and is the perfect weight. The past weekend I wore it snowshoeing up a mountain with over 1000m of elevation gain it kept me warm enough but not too warm. The only thing I wish is that it had reflective stitching on it. I actually have 2 of these jackets one in a size small and a medium the reason I have 2 is incase I want to put heavier layers under it as I will wear it for -20 activities and just incase I gain weight as my weight is on the low side right now and I still want to be able to wear the jacket.

Rated 2 out of 5 by from Pink zipper? Really? Zipper on the black one is pink but looks white in the picture. This is a deal breaker to me, unless I can figure out a way to change it without destroying it. I'm thinking about returning it, which is a shame, because otherwise it's awesome and is very well made. Columbia - I buy from you a lot, but your colour choices are starting to really frustrate me.

Rated 5 out of 5 by from I'm in LOVE! I wanted something for when I go hiking or when I go for a walk in mornings/evening when it's cooler out! Omg it just works - keeps me warm but yet I'm cool at the same time! I ordered XL because I'm large chested 38 DD and small on the bottom normal woman size 10. And was worried that the XL would be to big - but it wasn't! Again I'm love it just wish I could get in my other favorite color emerald green! hint hint Columbia ;)

Rated 5 out of 5 by from Love it! I got this jacket for early morning walks with my dog. It's definitely a light jacket and the sleeves don't block the wind so the vest area is warmer than the sleeves. It's a perfect layer for the early fall weather right now but won't be warm enough when the temps drop, which is fine but I did think it would be warmer given the omni-heat reflective dots. The bright color (haute pink) was what I wanted for visibility. It's an "active" fit so it will be fitted if you order your normal size. Size up if you want to have heavier layers underneath or if you like a roomier fit. It's cute, comfortable, and I like it for now and will like it again in the spring.

Rated 5 out of 5 by from Super Cute Spring/Fall Jacket I love this jacket - it is perfect for a Spring or Fall day when you need a light jacket. I am 5'9", approx 165 lbs, athletic build and a L fits great. The color I ordered (coral flame) isn't available any longer, but this jacket would be cute in any color. The sleeves are slightly thinner and obviously a different material than the core part, but the core has omni-heat, which is awesome. Great purchase.

Rated 4 out of 5 by from Great jacket for autumn/spring outdoors Love it! This jacket does run a bit small, I'd recommend ordering a size up to be ultra comfortable. I wear this for hiking and casual cycling (it's not long enough on me to wear for road cycling) and it's great. I wear a thin base layer but wouldn't really have to as the jacket does a great job of working with my body temperature to keep me cool, yet warm enough to be comfortable. I usually order a Large (I'm size 12, 5'6") and this jacket fits more like a shirt than a jacket on me. I love it so I'm keeping it, but will order another in XL. Sleeves are thin material, as they should be, so I wouldn't plan on wearing this as your only source of warmth on a winter day with minimal activity. Snowshoeing would be great but just standing around in the cold, this jacket wouldn't be ideal.

Rated 4 out of 5 by from Cold Arms The only thing preventing me from giving this one 5 stars is the arm fabric is VERY light and breathable and almost too thin to make this jacket useful for any type of windy day. It's almost like having bare arms and given how fitted the arms are, it's not like you could really wear anything on your arms underneath it. The body is a nice light cover up but would like the arm material to be a bit thicker/warmer. Otherwise, jacket is stylish, fits well and good for slightly cool weather.

Rated 3 out of 5 by from Nice Jacket but...... I wanted to love this jacket but I don't. It is a nice slimming fit and very comfortable. Unfortunately the zipper hits my neck and is very uncomfortable and the collar is not really made to turn down although you can kinda made it. The sleeves are a bit long which would be OK if there was a thumb hole. (my arms are short so sleeves are often too long for me) I would like it better if the sleeves had the padding that is in the chest. Maybe it would keep you warm but it doesn't feel like it will to me. Its going back.

Rated 5 out of 5 by from Kept me warm! We went for a horse sleigh ride in the snow in Leavenworth, WA and this kept me perfectly warm. Light sweater underneath and I wasn't cold at all. I tend to get warm really easy though so I always look for lighter jackets, this worked perfectly. Looks nice and did what I needed it to do.

Rated 4 out of 5 by from Ordered a size larger to fit me when I'm 22 weeks pregnant....way too small :( I wanted this jacket because it was so cute, light weight, and would keep me cool and warm for all day wear. I am going to Italy for spring break with middle school students and I will be 22 weeks pregnant when we head out. I ordered an size larger than I normally wear so that I would fit at that time, and when it came in, it barely fit that day, and I was only 15 weeks pregnant and not even showing yet. I am disappointed that it will not work for my trip, and I will probably have to return it. :(
