Good Jacket

  • Familiarity:I've used it several times

I do really like this jacket. It is very warm and packs down very well. However the sizing is a bit strange. I wear a L in almost everything and this jacket is a little big. The shoulders and arms fit great but the stomach section is baggy. But this does allow for additional layers if needed. Perhaps a medium would fit me better but I am afraid it may not fit in the upper body. I am 5'10 175. But it is a pretty cool jacket as 4 stars would indicate. I would probably buy something different next time, I miss having pockets. Great value also at $100

Crazy warm

  • Familiarity:I've used it several times

Used this jacket a handful of times, and I simply can't get over how warm it is!!! I'm certainly not a warm-jacket kind of guy (shorts & t-shirt are my bread & butter), but in the extreme cold this jacket kept me toasty. Medium was perfect fit for me (5'10", 180lbs, muscular build), but I like my clothes to fit snuggly rather than looser. Also, it compresses down to almost nothing - I'm confident you could cram it into a 1L nalgene bottle if ya needed to. Overall, awesome jacket.....the 1/2 zip is nice too for dumping heat (cause you may need to!!).

Awesome - near perfect.

    First, I have to say, WOW! This thing's warm, light, comfortable, functional, and stylish. That alone should give it a full five stars, and I'm really tempted to do so, but alas, I won't - at least lot for now. I know some people like to knit-pick others' reviews if an opinion or rating relates to personal preferences rather than specifics about the items themselves, but in my books at this point, the cumbersome pullover logistics of this 1/2-Zip won't let me give this jacket top marks.

    That's not to say I have a problem with it being a 1/2-Zip, because even suggesting that would beg the question: "Why did you buy a 1/2-Zip if that's not what you wanted?!?". I know it's available in a full zip. I also don't believe that if a size L is too small, that should impact how the jacket is rated, regardless of whether or not it's a loose-fit or a technical cut. Usually those kinds of complaints tend to point-out more about the ability to figuring out which size of jacket should be ordered, and possibly a deeper understanding of and comfort with one's own body size and image.

    I actually enjoy not having a zipper a all the way down, and feel like it's tailor to fit me perfectly when I'm in the middle of using it, regardless of what I layer under or over it. That's could actually be another plus, considering the full range of Marmot jackets, sweaters and shirts that complement this piece. Still, the two specific problems I find, are that:

    a:) unlike several other pullovers of various sizes I've owned and worn at different times,
    this thing's not all that comfortable to get into or out of, and more specifically,

    b:) the elastic cuffs tend to be a bit too snug to be able to easily get my hands in and out,
    or to be able to check my wrist watch quickly.

    All-in-all, I'd rate it a 4.8, but since we can't give or take away fractions of a star, I need to leave some room for any improvements it's successor might bring. Otherwise, I can't see anyone being disappointed with this buy!

    My temp rating

      I have three light weight jackets, the Montbell AlpineLite, Marmot Zeus half-zip, and a Patagonia Nanopuff pullover.
      I wore each outside at several temperatures after sitting for about 30 minutes. I stood still for 10 minutes in each. I wore no gloves, hat, or shell, and Patagonia expedition weight top and bottom, and hiking boots as the only other insulation.
      At 45f, all were adequate. The Nanopuff was only slightly warm, though it maintained the same warmth over time. The other two were both more than adequate. In a survival situation with this as your only insulation, any of these would have been acceptable, thought the Nano may not have been comfortable.
      At 35f, the Nanopuff started out cool and became slightly cold after 10 minutes. Without a hat, gloves, and shell, 35f is beyond its sustained capability. IMO the Nanopuff is a good layering garment, but its ability to replace a normal jacket quickly becomes questionable.
      With the 13.2oz Zeus at 35f, my hands and head were cold, but the jacket itself was adequately warm. Even without hat and gloves, one would survive at this temperature. Given a hat and gloves, the Zeus should be adequate if pressed to spend the night at freezing or slightly below. As the Zeus is only 3 ounces heavier than the Nanopuff, I see it as a far better general solution. It has DWR, a well-sealed neck closure and waist cinch, making it a far better solution in windy conditions as well.
      At 35f, even though my head and hands were cold, the AlpineLite was very warm. Unlike the others though, the Montbell has both a hood and hand warmer pockets. With the hood and pockets in use, the AlpineLite is not at all challenged at 35f. I repeated this in the morning at 27f and again it was totally warm. While the AlpineLite is initially heavier at 15.7oz, for either of the others to approach its temperature ability, one needs to add a hat and gloves, if not a shell.

      Why would you be out without a hat and gloves, at temperatures approaching zero? It's a shaky test, I think, because your body loses so much heat through the head. Try it again with a hat, even if you forego gloves, and my guess is that you'll take your jackets down another ten degrees, easily, possibly more.

      Have to agree. Good information but so many things can change in a non-structured test like that. A simple thing like how much food you ate and how long ago could change the "feeling" outcome of your test greatly. A more subjective test would be in a controlled environment with temperature measures.
