men's marmot reactor jacket
February 26, 2011

This fleece from Marmot is very comfortable and warm. it wears very well. I agree with the other reviewer on its strengths and weaknesses. I really wish it blocked wind better, as I've worn it snowshoeing and I've been chilled. I would advise always having a windproof outer layer with you when doing activities in the winter w this jacket. I do agree that it repels light rain and snow relatively well, but it isn't meant for this function. I like wearing it around town quite a bit. I think the jacket is a bit bulky for backpacking in all seasons except winter. It simply weighs too much to justify do that in the future.

Pros: Great design

Great Fall/Spring Jacket
October 15, 2013

Great jacket for fall or spring. Too lightweight for dead of winter wear but perfect for layering. The jacket is very packable and light. I like the pocket on the sleeve. Carried the jacket to DC recently and was perfect for the cool evenings.

Pros: Great design, Build quality

Reactor Jacket Comfort
December 14, 2011

I bought this jacket for wearing as a liner. However, I found the material to be lighter weight than what I needed. The other issue was the sleeves were a bit snug and not lined. Because of the lack of sleeve lining, it was very difficult to put your arms in and out of the sleeves, as the fleece material sticks to your shirt or sweater.

Cons: Bad design
Comfort: 5 / 5
