Great jacket. I keep is stuffed in my pack or jersey pocket for those cool down hill sections after a long climb on the bike. Perfect for adding a little wind protection or keeping the chill from a light drizzle away.

    I've had several iterations of Marmot's Ion windbreaker over the years, and this version is the best yet. All of them have been light and whisper quiet this one easily stows in its chest pocket. You don't even realize you have it on. This has a hood that doesn't roll up and out of the way. For running go with the similar hoodless Trail Wind version. Can't beat the price here at Sierra Trading Post. Highly recommended.

    This jacket is perfect for when you need just a little extra something to keep you warm, and it is compact enough that you will bother to bring it. The black looks stylish enough to wear out to casual places. It's water resistant, not water proof, but it still has been a nice thing to have on hikes when it starts sprinkling.

    This typically comes on most of my trips. It weighs next to nothing and takes up very minimal space. I've used it in light rain. I've used running in fall/winter. I've even used it tied to the back of my bike rack on an overnight bike tour for visibility (got the high-vis yellow/green color). Most recently I took it with me on a trip where we did Mt Marcy (highest in NY), biked to Mt Mansfield (highest in VT), hiked Mansifeld. I used it each day -- it got crazy windy at the top of the hikes, and it was chilly the morning of the bike ride so used it then too. You really can't go wrong having this in your arsenal. Especially for the price.

    It truly can be stuffed in a pocket and it's perfect when less than a jacket is required. I'm 6', 220 lb., and the large fits fine with room for a sweater if necessary.

    Take a look at the UPS tracking record for this product. It goes to Boise twice, takes a loop through Texas and Colorado and finally ends up on my doorstep 12 days after it started moving. The wind shirt was only a 5 ounce product and could have been mailed in an envelope. I think you should get some explanation from UPS or maybe not do business with them again.

  • “How breathable do you find this jacket to be when active”
    Asked by Toasty Toes from West of the Great Laramie Divide on 12/14/2014 10:36:13 PM
    • Very breathable, never clammy, soft and flexible against the skin.
      Answered on 12/15/2014 12:25:22 AM by Pacific Rider from SF Bay Area
    • It's plenty breathable but will get soaked if you sweat a lot, like I do when running. After a windy run, I notice it dries very fast when I'm cooling down and still outdoors. I've done some runs in it when in the 30F's and windy and I really like the way it takes the sting out of a cold wind and yet I stay cool and comfortable inside. Like the hoody to protect my ears from biting wind. Perfect for what I bought it for........super lightweight wind protection and stores down to virtually nothing when packing it on a trip and space limited. I live in Central TX, so days in the 20F's are rare, so haven't tested it in very cold conditions........would wear appropriate layers underneath for very cold.

    • I find the jacket to be moderately breathable. It's light weight and wind-resistant and well constructed.

    • Hard to say, since I'm not sure how to objectively rate breathability and I got it after most of the warmer weather had passed for the season. Its extremely light weight (the merest shell) and has rather open mesh under the arms and at the back of the neck. The couple of times I did wear it, I wasn't doing anything very strenuous.

      That's the best I can do, other than to add that its very thin/lightweight and its of high quality.

  • “How loose fitting is this jacket?
    I want to wear this jacket over a fleece
    Buy a size up from my regularsize?”
    Asked by Neeman from Colarado on 11/22/2014 9:49:20 PM
    • Its not especially loose fitting. I wear a medium and I just now tried it on with just a short sleeve T shirt. It fit fine and looked fine. There was some extra room, but not a lot. I'd say you could wear something a little heavier than a T shirt under it, but I wouldn't think you could wear anything too bulky under it. All depends on what you plan to wear under it and if you size up, presumably the sleeves and length will still be right for you. Hope this answered your question. This jacket is a nice shell, average roominess, but especially roomy though.

    • Not a snug fit. I would buy your regular size.
      Answered on 11/22/2014 11:20:17 PM by guitar man from new england
    • Yes. Buy up one size. The arms are generous but it is slim waist. I got a Medium and the waist is most likely 32-33" at the bottom. Great jacket, though. It breathes well, packs up small and has some style to it.
      Answered on 11/23/2014 12:28:24 AM by Pacific Rider from NA California
    • Yes, I would suggest going with the larger size.

  • “I usually wear a medium jacket and shirts. Just measured my chest, and I am at 41.25" inches.

    Medium or large?”
    Asked by Raymond, the fit backpacker from California on 9/13/2013 7:39:56 AM
    • If you hover your mouse over or click on the sizes the chest sizes are displayed.
      I.E. Sizes Available: M (Chest 39-41) Sizes Available: L (Chest 42-45) For a snug fit Medium, for a more generous fit go with a large.

  • “My chest measures 45 1/2 and I usualy wear a size XL in mens jackets. I see the XL in Marmot is 46-49. Does the jacket run a little big or small...would the L or XL be the best size for me.

About Marmot

Conceived in a university dorm room by a pair of climbing buddies, Marmot Mountain Works first opened its doors in the spring of 1974 in Grand Junction, Colorado. At the time, the base of operations was a 100-year-old stone building. That same year, the first Marmot down jacket was produced specifically for an action flick called “The Eiger Sanction,” starring legendary actor Clint Eastwood. In the four decades since, Marmot has continued to engineer reliable gear that exceeds the expectations of outdoor athletes. Today, Marmot tents, backpacks, outerwear, clothing and Marmot sleeping bags are still pushing the limits in the planet’s most challenging conditions, from the summits of the world’s highest mountains to the deepest river basins.
