Rated 4 out of 5 by from Very good California ski jacket I am picky about my gear and this jacket turned out to do the job I intended it for which is for skiing in Northern California. My initial hesitation with the jacket was the outside pocket configuration being horizontal vs. vertical. They actually work great for a phone as it keeps the phone vertical which turns out to be less noticeable than the phone laying on it's side. Like I said I am picky. I never planned to use this jacket with the liner zipped in since normal ski conditions in california don't require that level of warmth. However the liner is great to wear on it's own when not skiing. The jacket material is the right thickness for layering. Not stiff at all like I found in some other jackets. Two things I think could be better; the inside of the jacket could use a horizontal pocket and the velcro flaps on the wrists could be a little longer so you don't have a bunny ear. These are really minor things. Great jacket and definitely recommend. Note I have not used the jacket in a snow storm yet but I expect will perform as expected. If it does not I will update this review.

Rated 4 out of 5 by from Close to perfect Meets my requirements for an all-weather ski coat- pitzips; good closure on wrists and bottom; roomy enough for extra layers; high collar covering up to your nose;heavy duty zippers; decent level of waterproofing. Only two shortcomings: does not have place to easily hook your pass; and the hood is unlined.

Rated 5 out of 5 by from Great skiing jacket. It's a great light and maneuverable jacket. I've skied with it in Minnesota and Colorado and if the temps are below 20 degrees especially with some wind you'll need some good base layers. I would have preferred the exterior chest pockets to be vertical vs horizontal because it usually takes two hands to open and close them for how stiff the zipper is and their location. Very happy with the jacket overall.

Rated 2 out of 5 by from Not up to Marmot Standards I have many Marmot products and I am very fond of the brand. This particular coat has been a disappointment. I bought the coat two years ago. After the first season a seam let go on the sleeve so it leaked. I talked to REI they offered some advice to fix the problem myself but the coat was not under warranty. The leak was really low on the sleeve so it wasn't worth the effort. Shortly after the stitching fell apart in one of the pockets so the zipper does not work. I have purchased three coats in the 350 range all have lasted many years. One coat had over 15 years of use and another I still have and is fully operational. At this price point I feel a coat should last more than two seasons. The coat is very warm and other than the leak it kept me very dry. If you don't use the coat everyday or use it very lightly the coat is fine, just don't expect the coat to last under heavy use.

Rated 5 out of 5 by from Winter coat This coat is beautiful and warm. So much warmer than my old Columbia coat that I replaced. The down alternative is warm and light.

Rated 4 out of 5 by from Marmot KT Component 3-in-1 Jacket - Men's I wore the jacket skiing for four days. With wind-chill, temperatures were below zero. I wore Under Armour compression underwear, a UA shirt, and the jacket. In general, the jacket kept me comfortable. I failed to utilize the hood over my helmet, which likely would have improved my warmth.

Rated 5 out of 5 by from Whatever you need I finally caved and bought the marmot despite the price. This jacket is worth every penny. The quilted jacket is exceptionally comfortable, and the shell does exactly what it should. Would definitely buy again

Questions & Answers

Can you advise comparative warmth between this jacket and TNF triclimate thermoball? About the same? Hard to compare different synthetics and densities.

Asked by: Jglover
As somebody who has actually owned both of these jackets, the Marmot jacket is warmer than the TNF triclimate thermoball, hands-down no comparison. If you are referring to TNF snow thermoball jacket would probably be about the same in terms of warmth, but I would still opt for the Marmot jacket, I still think it is warmer than either of TNF jackets (and is much easier to move around in).

...and what is the difference between MemBrain 10 and MemBrain waterproof material (Marmot Castleton vs. Marmot KT)

Asked by: Eaglestare
There is no difference, both jackets use Marmot's 2-layer MemBrain waterproof, breathable, coating. The "10" is a typo. Thank you for bringing this information to our attention. We will update the product listing on REI.com as soon as possible.

Are the chest and waist measurements in the size chart the measurements of the jacket or of the person? In general does this jacket run small or large? I am trying to buy it as gift and guess size. Do you think a 5'10" 170lb guy would wear a M or a L?

Asked by: Rabbot
The measurements in the size chart are body measurements. The jackets run large. For a person that size, the medium should fit best.

Does this jacket have the extra range of motion in the arms such as the "angel wing"or gussets? Warmer than gorge 3-1 in your opinion also?  thanks

Asked by: KnightWanderer
The Gorge Component Jacket has Angel-Wing Movement in the arms and will offer better mobility compared to the KT Component which does not have the Angel-Wing Movement feature. Based on the overall weight and face fabric, the Gorge will be the warmer jacket.
