Aconcagua Light ML Hooded Jacket - Men's

Awesome lightweight jacket for walks and everyday wear

Great Secondary Layer

This is an amazing layer, great fit. Hood is perfect. Pockets have easy access

Early testing

Great fit. Warm and I love the hood. Still early and no big trips yet. Only used it on day trips. Works well in a harness.

lightweight and warm

Love this and the way it fits. Perfect for under my rain shell and by itself. I have people asking me about it all the time. Looks good and feels good.

Older version was much better

This jacket functions as a light fleece hoody for being active on chilly days rather than a performance-oriented layering option for climbers. A disappointment given the previous versions of this item and the price. I have two older versions of this item, which are by far my favourite performance mid-layer, much better than mid-layers from Pata or Arc. So I was very disappointed the newer version is much worse. 1) the cut of the jacket is no longer fitted, it is more like a relaxed fit rather than athletic fit. The older version fit with a very slight compression, which I look for in a performance mid-layer. 2) the face-fabric is much more fragile. After a few brushes with rock while climbing, the newer version has already started to pill, whereas my older ones have held up for 2+ years and much more abuse. 3) Missing thumb-loops from previous version.

Nice mid-layer but runs large

I got this for my husband and he absolutely loves it! Makes for a great mid-layer on cold days or as a stand-alone jacket for warmer mountain endeavours. My husband got a size M and it fits more like a L, highly suggest to size down.

Warm but delicate

This is a great sweater, the perfect weight to add through the spring and early summer. Lightweight and form-fitting makes it a great layering piece. I will just note that the material is prone to pilling. I wore it on a climb and the rock chewed it up pretty good. It didn't rip just pilled all over, could benefit from a durable outer shell for climbing I guess. Otherwise, a great piece of gear, still wear it a ton!

Great Fall/Spring Climbing Layer

Great fleece that has movement mirroring stretch. Warm yet fits tight against the body for easy layering. I wore this multiple days on our RRG climbing trip this spring, over a baselayer, under a synthetic jacket. I wore it climbing all morning, its plenty long to fit under a harness. I normally wear a medium in most brands ( 6' 175lbs, 42" chest ) but take a large in Mammut yet it still fits snug, due to the more European cut.

My new favorite lightweight jacket. Early morning trail work favorite!

Functional Jacket

Just spent a week wearing this on a BC ski tour. It worked great and (like others have suggested) it's a great replacement for anything with Polartech Powergrid. Not as heavy as the powergrid but just as warm. Didn't think much of the pockets at first but they came in handy for small items throughout the day. The size L was just right for me. It fit trim (I'm 6'2" and 185lbs).
