    What do you think about this product?

    Have questions about this product?

    Blue is darker in person

    • Familiarity:I returned this product before using it
    • Fit:True to size
    • Size Bought: Small

    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.

    light weight warmth

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

    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...

    Marmot love

    • Familiarity:I've used it several times
    • Fit:Runs large

    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

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

    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.

    Nice fleece.

    • Familiarity:I've used it several times

    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.

    Hard to fit "athletic" body

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

    This jacket is soft, comfortable and the Polartec membrane makes it possible to wear it as an outer layer on relatively calm days. However, being a tall and somewhat slim guy (6" 2', 177lb), Marmots just does'nt fit well. The medium had too short arms but nice width, and the large had ok arms but too much width. Kinda felt like wearing a tent... I sent both of them back in exchange for a Norr�na Falketind, L( which btw is awesome!).

    I can add that the reason I wanted a slim-fit fleece was because I plan on using it as a mid-layer under a Patagonia Triolet shell, and therefore wanted as much mobility, e.g. as little extra garment as possible.

    Marmot makes great quality

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

    I have owned three Marmot fleece jackets, and I just purched two more (slate gray and fatigue). While the Marmot quality is superb, I find that the medium size runs a bit small. In addition, the sleeves, especially from the elbow to the wrist, are very tight. Difficult even when wearing a lightweight long sleeve shirt under. There's no way I could wear a sweater under this fleece. Backcountry.com is great!

    Light Fleece

    • Familiarity:I've used it several times

    Exactly as the title says, it is a lighter weight fleece perfect for cool days/nights and a great layer option because it is light!



    I wear this when the temps are in the 50s and use it as a layer in the winter underneath my down jacket. I love that is has hand pockets, never know when you need to stash something or keep your hands warm on a breezy night.



    I am 5'11", 230#s and order an XL. Fits great and I can still slip it over a long sleeve or base layer.

    Good gear...

      Purchased this fleece jacket to match with a Marmot waterproof shell, and it's fulfilled this role well. The manufacture quality of both items has been great. The products are quite durable.

      It's a basic fleece jacket, so not much more to add.

      Great Fleece

        Couldn't be happier with the reactor fleece. It's lightweight, warm, and ridiculously soft. Great as a mid-layer or standalone.

        Runs a little big (like most Marmot stuff), so I bought one size smaller than I normally do l for a perfect fit.

        Great fit, great feel.

          It is light, it is stretchy, great for not so cold conditions on its own, windy it needs a wind shell, have used it in cold conditions as a layer, will be purchasing a second, as i love the first one so much. Fantastic cut and great for any sport where you move alot.

          Can this fleece zip into a Marmot shell?

          Can this fleece zip into a Marmot shell?

          Best Answer

          This question was answered below, and as stated there: "No, only the Marmot Warmlight fleece and the Cauldron Jacket and Vest are zip in compatible."



          You could easily wear this fleece under any shell though and it will work perfectly fine. There isn't really a need to zip the two layers together.

          Just purchased this jacket as I was looking...

          Just purchased this jacket as I was looking for a light fleece for foggy, or chilly early morning / evening hikes and am planning to wear my Patagonia Houdini as a light shell (light rain) if needed.

          I am 6' on the nose, and weigh in at 210lbs with a 45" chest. As always smack dab in the middle of everything when it comes to size charts. I ordered the XL as I prefer a slightly looser fit, but had heard Marmot runs a bit big (not so with my Precip jacket I purchased 6 years ago). I know I can exchange, but wanted to know if XL is the right size.

          Thanks

          Is this zip-in compatible with the Marmot...

          Is this zip-in compatible with the Marmot Tamarack?

          I have a Marmot Precip jacket, would this...

          I have a Marmot Precip jacket, would this fleece fit under it? Would this be a good combo for skiing?

          Is the Reactor jacket fairly light weight...

          Is the Reactor jacket fairly light weight fleece?

          Best Answer

          Peter,
          Thanks for your question. The Marmot Reactor is built from Polartec Classic 100 weight fleece. There is 100 weight, 200 weight, and 300 weight fleece in the Polartec fleece family. That being said, the Reactor is lightweight, and would work great for three season use. I hope this is helpful for you.
