Strange Appearance

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

I'm not crazy about the waffle texture fabric (even though it does add warmth). Also, there appears to be too much fabric below the zipper on the left side of the chest. That area sags and hangs badly, leaving me looking like a failed science experiment. Had to return it.

I'm 6'3 and 200lbs athletic build, should I get a Large or XL?

Responded on

Hi Evans,
I'm 5' 11" and 170 pounds, medium build. The large fit me fine. Looks like the XL will be good for you.

A great fleece for layering

  • Familiarity: I've used it several times
  • Fit: True to size

Short version: A thin yet surprisingly warm fleece that breaths well enough to prevent over- heating.

Long version: I'm actually wearing this fleece as I type this review. I liked my full zip Alpinist so much I wanted a second in another color and opted for the 1/2 zip. I very rarely get 1/4 or 1/2 zips because I overheat easily and like having the ability to really open up a full zip. But after being impressed with the breathability of the full zip Alpinist, I had no doubt I would be very happy with the 1/2 zip. I wasn't disappointed. I find it to be very warm yet breaths well when you are active or once you make it back indoors. The micro- grid fabric is also ver durable and doesn't show wear after some pretty serious use. A great layering piece as well due to its thin nature.

How I use it: pretty much the first thing I grab when I need some extra warmth, and a great piece to layer under a outer shell

What I wouldn't use it for: Not a windproof fleece if that is what you need.

Fit: I am about 6' and 185 lbs and use a medium. I find it to be a very comfortable athletic fit that never restricts or feels too tight.

I would caution those who are expecting something 'really' heavyweight. Compared to, say, a polartec power stretch - which I consider 'heavyweight' - this is no where near as thick/warm. I even asked the rep before buying and he said this shirt was almost like a light jacket. Unfortunately, not true. Seemed like a perfectly fine shirt - if that is what you were expecting - but I'm returning it because the description (both product and by the rep) led me to believe it is a LOT heavier than it actually is.

I wear small for Marmot ROM jacket, witch size should I take for for the Marmot Alpinist ?

Responded on

Hey Peter,

I am going to suggest staying with the same sizing even though the ROM is an athletic cut and this is only a regular. The biggest difference you will see between the two cuts is that the ROM will be a little trimmer in the body.

Light and warm...great for mild days

  • Familiarity: I've used it several times
  • Fit: True to size

I like the material, soft yet warm! Nice fit, close but comfortable for me, I got a medium as a 5ft 9, 155 lb guy.

Comfy Cozy with Features

  • Gender: Male
  • Familiarity: I've put it through the wringer

This is a warm comfortable fleece, that I really like. It's long enough in the back and arms. The thumb loops are a bonus, that you can use or not. The chest pocket took a little getting used to, but now I stash some cash in there. A good choice among the many base layers out there.

All size M parameters fit my physique...

All size M parameters fit my physique perfectly except chest circumference. I'm 2" bigger. Do you think I should get M size and will it stretch comfortably? I'm afraid that if I get L it will be too long.

Thank you.

Get a large. The alpinist half zip has a very athletic cut and may be far too tight. I am usually a small in marmot products but I own a medium in the half zip. Much more comfortable.

Responded on

Thank you! I was just afraid that L will be too long. Is your M length (sleeves and body) OK considering that you wear S?

Responded on

The sleeve length is fine. The sleeves are a little longer due to the thumb holes. The piece overall is a little shorter so it may be a touch long but it doesn't bother me.

A Colorado Essential

  • Gender: Male
  • Familiarity: I've used it several times

This is a very warm and light weight fleece. I plan on wearing this fleece on cold winter days and as a base layer under my ski jacket. I pair this fleece with my Marmot Rom jacket for a nice little combo to climb in. The thumb holes are very useful to help prevent the sleeves from riding up when climbing or skiing. I ordered the small and the sleeves are a great length but I with the waist was a tad bit longer. Over all I am very pleased with this fleece.

Responded on

can you tell me your measurements because I'm trying to determine size for me. You said you got S, how tall/chest circumference are you?
Thank you!

Kick A$$ fleece. I wear it all the time for just about everything. Excellent fit and nice wind taping on the Napoleon pocket zipper.
