Why We Like The Mammut Aconcagua Light ML Jacket

The light version of Mammut's classic performance fleece, the Aconcagua Light ML Jacket has the versatility to work for a whole range of outdoor activities. The Polartec Powe Grip fleece hangs on to our body heat for lightweight insulation while also wicking moisture and breathing if things get steamy. It's also synthetic, so it insulates when wet and also dries quickly—making it more low-maintenance than down. The Aconcagua's warmth-to-weight ratio makes it a nice outer layer for mild weather, and its close-to-body fit layers easily under a shell for a shoulder season mid-layer, too.

The jacket is very comfortable, but do wish I purchased my regular size rather than sizing up. I've worn it with the thrift base and a down vest in 30-40F weather and was definitely comfortable when the temps were close to 40F. I can see this being a great light jacket for warmer weather and certainly works as a mid-layer for those going indoor/outdoor. It's a bit too lightweight for me, if I'm spending a lot of time outdoors in the cold. Looking forward to taking it traveling!

Close fitting and lightweight warmth

I purchased one of these on a whim and now I have gotten another 2. These have become my favorite added layer on cool spring days and summer mornings/evenings. The jacket is tight fitting, but not restrictive; it's a great mid layer as well. I find it breathable. I typically wear a US size 6 and own size S in this jacket, since I like the tighter fit which I'll usually wear over a fitted base layer. I'd definitely size up with you want to put more layers under it.

Comfortable, warm, but not breathable

This jacket is soft, comfortable, and provides good warmth while being small and light. However, I only wear it for belaying, easy climbing, or hanging at camp because it is not breathable enough for hiking or really anything that gets your heart rate up. The lack of pockets is also a downside but does contribute to the lightness.

So Versatile

I purchased this on a whim, but I have ended up reaching for it again and again. It is surprisingly warm, but breathable. I have used it kayaking and hiking in the early fall, and just this AM I used it for a paddle on a mountain lake with weather in the low 50s. It's my favorite light jacket for slightly chilly AMs. It's fitted, so it's comfortable to wear alone or over a light t-shirt. I typically wear a size 6 and found the small to be perfect. I might recommend sizing up if you want a looser fit, but I find the streamlined fit to be both comfortable and flattering. Looks like I'll be looking for more of these!

Use it all the time

This is my go to mid-layer! It's super warm but light. I use it as mid-layer for mountaineering, hiking, ice climbing or as a jacket on its own on chilly days while rock climbing. The quality feels great too!

I got both the regular Aconcagua jacket and the light version for different weather conditions. I really wanted to love this one more because of the pretty color and style. However, I wish this jacket was just slightly thicker and I find the size runs a bit big.

This jacket is the perfect weight and fit for layering as we move into cooler weather.

Great Long Sleeve, but White Gets Dirty

I really like this long sleeve. It's great for spring skiing and layering over a tank top. The white colored one gets too dirty too quickly.

Great breathable midlayer for winter!

Excellent light midlayer for high aerobic winter activities. I've worn this on a few ski tours under my softshell with temps below -15C and had excellent moisture management. I found the medium didn't fit quite as snug as I was expecting (I'm 5'9 and quite slim, typically between a med-small in most brands), but with how stretchy the fabric is I find I can get a 200 weight merino baselayer underneath without the uncomfortable compression effect that some layers cause.
