    Keep comfort close.

    There's little comfort involved with waking up before sunrise for mountaineering missions, so make sure your baselayer feels as comfy as your bed whether you're sweating through a steep tour or making a final, rocky push to the summit. The Mammut Men's Moench Advanced Top is such a baselayer, with Polartec Power Dry fleece wicking moisture and drying quickly to keep soft and warm throughout the trip. There are Polartec Power Stretch panels that ensure freedom of movement designed specifically for touring and mountaineering.
    • Baselayer built for alpine touring and ski mountaineering

    It's Hot Hot Hot

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: Large
    • Height: 6'0"
    • Weight: 160lbs

    Like anything Mammut, this piece is incredibly well thought out and designed for with specific use in mind. The first thing I noticed wearing it around the house was how warm it was, even for a midweight fleece. Definitely great out on cold days climbing and likely ski touring, although I haven't had a chance to use it yet due to a lack of snow around Utah.

    While, as the review below mine noted, the fit is slim and feels strange at first, one thing I noticed was that in wearing it around a bit, it stretched out slightly to accommodate my shoulders which felt tight at first. Similarly, even though the armpits felt snug at the beginning as well, they loosened up and I don't notice any places on the fleece that don't fit well anymore. Almost as if in wearing the piece it stretched just enough to fit me perfectly.

    At 6'0 160lbs I would say it fits true to size as I went with a size L. But, if you want to wear anything underneath it other than a t-shirt, I would size up!

    Armpit fit sucks

    • Familiarity: I returned this product before using it
    • Fit: Runs small
    • Size Bought: Medium
    • Height: 5'8"
    • Weight: 155lbs

    The materials and overall design of the shirt are quite nice. It seems like they added lighter material to all the hot spots where i get sweaty and hot the most and the thumb holes seem to be well laid out. I have always been a big fan of mammut's products. This shirt however was designed super weird and despite the overall good design its completely ruined by the fit around the armpit area which is just way to high. Ive never felt a shirt before with armpits that were cut so high. I am a slender 5' 8" 155 lb lean male who either wears medium or small shirts typically. I bought this shirt in a medium since it was a slim fit and despite being skinny I couldn't even fit in the medium. The sleeves on the shirt are the right length, the over all length of the shirt is great but the armpits are just to high that they dig into my armpits and the bottom front of my chest very uncomfortably. I really wanted to like this. I dont know if i will try the large or not. If you buy this shirt definitely size up unless your a twig.
