My boyfriend really liked this jacket other than the arms were a little short for his liking. He is 6'0" and found the length of the sleeves to be short. He said it was very warm and comfy. Loves it for care camping or for walks during the winter..

This is everything I want except the ability to layer. The quality, material, and color are great. The forearms are so tight it was uncomfortable to wear anything other than a short sleeved shirt. A heavier sweater was uncomfortably restrictive. There is no coat hanging loop, or drawcord for the hood if you care about that. Sadly, I’ll need to swap this for something that fits my Arms better.

This coat is incredibly warm for its size. Not quite as light as a down coat of similar volume, this coat surprised me with how warm it was. I wore it in 25 degree weather and was very comfortable with a light vest (patagonia nano air) underneath. There is always a loss in packability with synthetic versus down, so this coat is a perfect layer for camping in the mountains but perhaps not your ultra light backpacking trip. The length of the large was perfect for 6'3" 200lbs. Most larges are a just a tad short where this was exactly what I want a large coat to fit like!

I'm traditionally a bit skeptical on synthetic insulation. this thing flipped me. Light, warm, and puffy, you'll never have to worry about leaking feathers or clumping. Also quite stylish in my opinion. The jacket only has the features you need. 2 hand pockets, 1 chest pocket, waist drawstring in the hand pockets, and a hood that doesn't get in your way--on or off. Stuffs down small for easy transport. I loved this thing.

This is a great jacket alternative to down! My husband wore it and he said it kept him really warm! It's cozy and looks great. Because it's synthetic it doesn't compact down quite as small as a down jacket, but it felt just as light and warm as any of his down jackets. Hasn't worn it when it's rained so I don't know how water resistant it is. Overall, big fan!

Keeps out the wind, weighs next to nothing, and keeps offers down warmth without down drawbacks. Super pack able and can handle frigid days, but maybe a little too well? It can get too warm in this jacket. It can also be louder than I want when just walking around. Plus, the sheen isn't quite my style.
Still dig it though!

I tested the Avant exclusively in my home state of Colorado up to elevations near 13,000 ft. in a range of weather from -5℉ (-20.6℃) and dumping snow to sunny and 55 ℉(12.8℃). During that time I really came to love the puffy for its warmth, durability, and ability to excel on each of my adventures. On hut trips I typically head out into the night with a big puffy jacket and pants to photograph starry skies over the cabin but on both of these trips I substituted larger puffy for the mid-weight Avant. Filled with synthetic insulation the equivalent to 700 fill power down it kept out the cold nicely while standing still at 5℉ (-15℃) when worn with puffy pants, below that temperature I started to feel the cold unless I got moving to generate more heat. While skiing a full day at Copper Mountain I was almost perfect from the cold snowy morning to the sunny blue-bird afternoon; I briefly got hot when working harder in steep moguls and north facing back bowls. It's definitely too warm for me to wear when skinning uphill, but I'm usually only wearing a thin shell or base-layer at that point.

Got this one. Runs a bit smaller in chest but the sleeves are Ok! No hanging loop inside and no inner pockets. But I like it!

I love this jacket. No critters suffer in the making, and it performs extremely well. My buddy and my girlfriend both bought one after seeing mine. It's quite warm, and it does much better against wind and light rain than I expected from a puffy. It's lightweight and durable. Compresses pretty well. Layers nicely (I put my Marmot Mobilis over it, or my hard shell, for great snowy/wet day protection). Has a zipper guard at the top for us bearded guys. Couldn't ask for better from Marmot, and I will definitely buy another one if mine ever gives out (or maybe even before!).

I think it's true to size, it pinches me in the armpits just slightly when I reach my arms forward, but not as much as most jackets do. I have a pretty broad chest and back for my smaller size, so this is almost always an issue for me.

Chances are if you show someone who hasn't seen the Avant before and ask them if it's down or synthetic, they'll have a hard time guessing. Marmot is continuing to blur the lines of synthetic vs down, and the Avant is the best yet! It's just as warm as a 700fill down jacket, and maintains nearly the same warmth to weight ratio. But...it keeps you warm when wet. The Avant is the obvious choice. The cut is on the athletic side with a more durable woven baffle throughout. Approved by ducks everywhere!
