Stay cozy in the Reactor 2.0 Fleece Jacket with lightweight Polartec warmth and breathability
What Our Gearhead® Experts Are Saying:
"I wear the Reactor 2.0 as a daily midlayer—it’s warm without being bulky and breathes well on hikes. The fleece is super soft, and the flatlock seams make it comfortable enough to wear all day."
Sometimes lightweight warmth is all we need to stay comfortable from the trail to town. The Marmot Reactor 2.0 Fleece Jacket is built with Polartec Classic 100 microfleece, giving us soft, breathable insulation that dries quickly and layers easily. Whether we’re using it as a midlayer under a shell or wearing it on its own during cool evenings, it’s a versatile piece we’ll keep reaching for year-round.
Thoughtful details make the Reactor 2.0 even better. Flatlock seams reduce chafing and allow smooth layering, while a wind flap and chin guard help block out chilly drafts. Zippered chest and hand pockets stash essentials close at hand, keeping us ready for whatever the day brings.

Expected more from this brand.
[This review was collected as part of a promotion.] Quite thin and unimpressive feeling material. Not impressed. Returned. Have purchased Marmot products before that were good quality but this one certainly doesn't make that list.

Lightweight warm and comfortable
Lightweight, warm and comfortable. I purchased one two years ago on clearance and it quickly became my favorite fleece. It is very thin and lightweight, and it is very comfortable and warm. We keep our house on the cool side so I will wear this everyday in the winter. The fit is true to size however as some people have mentioned, the sleeves and torso are longer than most. I prefer that added length/fit. Can be worn as a first layer or alone. I was happy to see it back on clearance and ordered another one as my original is starting to wear out. I consider this as my favorite light but warm sweater that can be worn year round.

Please stop lowering the quality
Way thinner than the last model, barely a fleece. The reinforcement on the coffs is great and, and the elastic in the bottom is gone too. I get it, things are getting more expensive, if you have to raise the prices, then you need to do it. Marmot is a good name, don't make it "was" with cheap non durable junk.

Very good fleece. Enjoy the sale price!
[This review was collected as part of a promotion.] This is a very good fleece! It is thin but does the work. It is extremely comfortable. That’s why I bought another one in different color.

Comfortable and versatile
[This review was collected as part of a promotion.] This is a comfortable and versatile jacket. The fabric is smooth and isn't bulky. In cold weather it can also be worn under a heavy coat. I bought it to replace an earlier version of which after about 14 years of very regular use is beginning show a bit of wear. Looks good in both casual and slightly dressed up settings. I live in the San Francisco Bay area where because of the micro-climates, so this my go to jacket to cover a range of temperature variations.
