    Lightweight warmth abound.

    From exploring alpine lakes in autumn months, to navigating bustling city streets come December, the Marmot Men's Astrum jacket brings you warm protection in a lightweight package. Crafted with a tough and stretchy nylon fabric, this jacket resists the abrasive surfaces of granite rock and building walls alike, yet still allows maximum flexibility when you're out galloping around on your next adventure. And, when temps start to head south, the Thermal R Active, synthetic insulation does its part to keep you warm, while an AirExchange lining works hand-in-hand with the lining to cool you down should the temperatures turn heel and warm up again. Additionally, an adjustable hem, hood, and cuffs let you customize your protection to match the changing weather, and two zippered pack pockets store your daily essentials in a secure fashion.

    Warm and Synthetic

    • Familiarity: I've put it through the wringer
    • Fit: Runs large
    • Size Bought: medium

    I really like this jacket. It's comfortable, warm and breathes well. I think it runs a little big. I have the Medium and it is the biggest Medium I have. I was actually able to get a small on and zip it all the way up. I have a 38-39 inch chest. The jacket is really warm though. I dig it.

    Nice except for the the price

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: small

    I'm 5'6" and athletic, and the medium in this fit great. Marmot is one of the only brands that seems to fit me well, not too slim, and not too baggy. I would say the main reason I didn't keep this jacket is that because for the price, I would have expected something either warmer or lighter. This feels like a fall jacket to me, and I couldn't justify the price for that usage.

    Its a great piece... but not an amazing

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

    If I could give 3.5 stars I would. There is NOTHING wrong with this piece. It IS very nice.

    I was looking for an synthetic midweight jacket/hoody... and this is just that. Everyone makes one of these with small differences. Patagonia's Nano-Air, Arc's Atom and LT Atom Hoody... etc. etc.

    What I liked - I liked the roomier fit and the wider back. It has a non-technical feel to it. There is a small amount of stretch in all the material. Love the hand warmer pack pockets.

    What did not work for me - I found the Large a little too roomy, sleeves a touch long... but the medium too small. I found that I really wanted a vertical exterior chest pocket.
    The internal zippered pocket is on the left inside ... which bugs me... feels like is should be on the right.

    Very Nice piece but did not blow me away. I't trying others... trying not to buy a Arcyterx Atom Hoody... Why - because I know I love it but I have the jacket... and the Lt. Weight Jkt... and want some diversity... but maybe I don't?

    Light, warm, clean

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

    I've been using this for resort skiing, touring, camping, and just wearing to the office for the last 2 months. It has a nice, clean appearance and fits me really well. The arms seem to be just a tad longer than expected for an insulation piece but this is not an issue. I will update this review after a full season of use.

    Light, warm, clean

    awesome insulator

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

    Love this jacket. With all the options out there, I opted for this one because of the stretch and the feel of the fabric Super warm for how lightweight it is as well. The shell is reasonably durable for how soft it is. I have been wearing with a t-shirt in about 40 degrees and very warm and then dropping into the low 30's and still comfortable. Lower temps than that, I have put just a long sleeve on and have been fine. It fits well. I am a medium in most everything and this fits great in that size.

    Great Jacket

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: L

    I bought this jacket as an impulse buy, hearing about the stretch it has and the awesome synthetic insulation.
    I'm glad to say I haven't regretted my buy.
    It's super warm, and blocks a fair amount of wind as well. I wear this jacket riding my motorcycle at temperatures around 40 degrees going 70-80 mph and I have been decently warm. The hood adjustments work really well on my helmet, and I imagine would work just as well on a ski or climbing helmet.
    This is an awesome buy, Highly recommend this jacket.
    The only con I've found with this jacket is that it is kinda baggy. It'd be perfect for layers underneath, but the overall feel the jacket has a loose and relaxed fit to it.

    Great Jacket

    • Familiarity: I've used it once or twice and have initial impressions
    • Size Bought: XL

    I just got this jacket and I like it. Warm and cozy are the first two words to come to mind. I wear a XL and this one fits great. It is a regular fit so you can have some layers under and looks slick enough to not only wear at the campsite but also out on the town. Overall a great piece I highly recommend.

    Sick jacket

    • Size Bought: Medium

    This thing's legit. I had been looking for an insulated jacket for a camping trip spanning Redwood National Park, Crater Lake, and Lassen Volcanic National Park this past week that was filled with various hikes and a few chilly night time camp fires/beer sessions. Honestly I can't say anything bad about it.

    It got put to the test during a hike up Lassen Peak. It was snowing and around 36°F at the base/beginning of the hike, and ended up being around 28°F with strong winds at 10,400'. The Astrum jacket and a single t-shirt underneath kept me comfortably warm the entire time and wasn't restricting at all. The only thing I wish I would've had were some gloves!

    Side note, I live in Santa Cruz, CA, so those temps were really cold for me. I began the hike wearing a Marmot Minimalist jacket (size M) over top of the Astrum jacket, which actually turned out to be a pretty sweet (and waterproof) setup. I got warm wearing this combo during activity, but I was pretty happy I could layer both jackets.

    While hanging around camp I wore it with a flannel shirt underneath and stayed comfortably warm.

    I also find Marmot to be a bit longer than some of Patagonia's insulated offerings, which is appealing to me as well.
