Perfect for those crisp 55 degree temp.
I work on the Colorado river and was looking for something lite but warm and this sweater jacket was exactly what I needed for the morning cold. Also works as a good 2nd layer. I agree with previous review that the shoulders were big or odd shaped, however after a wash and some wear they now fit me perfectly.

Shoulders are a bit wide
Ordered in a men's small Mallard green. The color was even better than the picture, but the fit was a bit strange. All of it fit great, but the shoulders were a bit wide, and because they were made of a different material, stuck out as if they had shoulder pads.

Warm and Light
I was searching for a technical fleece to use hiking, climbing, and skiing a few weeks ago, and picked up some fleeces. Between the ones I tried on, I like this one the most for the price! It was warm, lightweight, and inexpensive. However, the cut was a bit too baggy on my sides, and I opted with the Patagonia R1 instead due to it's slim fit and longer hem. Still, I gave the Reactor to my buddy cause it was so darn inexpensive!

Decent fleece layer
The jacket feels really nice and lightweight. If you looking for a nice 100g fleece layer then this is the best bang for your buck. This jacket has a regular cut so it doesn't fit to my body as well as my other athletic pieces. However, it leaves room for layers underneath. Still, it is quite loose in the stomach area that I only reach for it when I want something loose for hanging out or lounging around.

Great Light Weight Fleece
This light weight fleece is unassuming, but stands up to the cold when you need it the most. It's cut slim so it fits under a light jacket for that extra layer on a cold day. It doesn't do much in the wind, but if you wear it under a wind breaker you're in business. I like the full length zipper so I can easily adjust and regulate if I get too warm. I recommend this jacket. It has kept me warm on some very cold early spring days in New York.

This fleece is terrific! It's thin yet cozy which makes it awesome for layering. I generally wear a large but went with the medium and it fits me well. This is a perfect fleece jacket for someone like me who enjoys the fitted look.

Does as claimed. Cilantro is green lol
Very good quality. It's slightly larger than my other medium sized clothing. The only problem I have is cold wind blowing. If I wear I anything else with it, I heat up quite quickly, even below 30 degree weather. It's breathable, just as they claim. It dries very fast as well. Poured a little bit of water on it, and it disappeared; it was completely dry in seconds. Wore it running and you couldn't even tell I was sweating. The only problem I have is that the Cilantro looks yellow on all of my devices. If I had known it was a light green, I would have gotten a different color. I expected green, but was hoping for the off yellow, as it is very hard to find yellow clothing.

This marmot fleece is supersoft and really sharp looking. I originally bought it for strictly an underlayer, But was surprised with how stylish it is. I will definitely be wearing this throughout fall, and on hikes with one layer under, also the Alpine green looks better in person than it does on line. New favorite fleece.

Warm on a still day
This fleece has served me well. It is a little baggier through the body than I like but maybe I wear my clothes too tight. The fleece is warm when layered under a windbreaker, but on its own the lightest breath of wind cuts right through it.

Very satisfied so far
I've only had this jacket a short time, but I'm really pleased with how it performed. I wore it on a chilly morning hike in the White Mountains in early March, and it plus a base layer were perfect for keeping me warm but not sweaty while hiking. More importantly though, it held up beautifully when our hike went a little off the rails. When the trail got icy we kept climbing higher than we probably should have even though we didn't have any spikes or crampons. That meant a bit of bushwhacking through branches, and several unintentional falls as well as a couple intentional slides. The jacket slid over rock and rough ice and pushed through thick branches and underbrush without any apparent signs of wear at all. It's also nice and lightweight, so there's no real downside to taking it along. I think this will be with me even through the summer months when it's warm enough that I won't usually need it. We'll see how it holds up over prolonged use, but I put it through a lot more than I should have this past weekend and it held up wonderfully.

First, the material is incredibly soft and super warm. The quality is second to none, the finishing touches on the stitching and Zipper quality are great. I used it as a second layer when we had the coldest temperatures in NJ in 20 years at 28 below 0. It is a bit long at the waist line, however I'm 5'7" 215lbs and I did get the XL. Overall OUTSTANDING, and I would buy it again. I'm sold on Marmot products.

Blue is darker in person
Before I share anything about the product, I love blue. All shades of blue. I think this jacket works marvelous for mid 50 temperatures in Utah. Not too cold, nor too hot! Unfortunately upon receiving it, I didn't like the color of the jacket (first time I didn't like a shade of blue). Otherwise everything is great.

Marmot to the rescue!
I had a problem with this jacket and Marmot replaced it and restored my faith in their product. Thanks Marmot!

light weight warmth
Great light fleece jacket for cool temps..The fleece is very soft and comfy. I use it as a outer layer and when temps demands you can layer it over base layer and layer over it with precip jacket for temps down to around twenty degrees for a light weight none bulky layering system...

This "jacket" does the job. I appreciate its lightweight and powerful warmth. I use it for everything I do outdoors and it never disappoints. I'm 6' 1" 180lbs with an athletic build and I had to send back my first buy of a Medium in exchange for a Large and it fits ok. I feel it runs a little long but the added length can be utilized. The Medium fit great except it was tight around my chest. Other then the added length of the Large it fits great otherwise. Love me some Marmot!

Typical Marmot Quality
I have a lot of Marmot stuff. Bought the Reactor fleece as an addition to my layering system. It is classic fleece, meaning it is warm but not windproof. I didn't expect it to be. I am 5'9", 34 waist and wear a medium. This fits me true to size. The jacket is sharp and great as a mid-layer or stand alone for warm ski days or around town. Highly recommended.

Just what you want out ofa fleece jacket....warm, comfortable and just right as a baselyer under a shell. True to size, like all the oher Marmot stuff I own. You can't go wrong with this piece.
