The Mammut Mercury Jacket has become my favorite jacket. From negative ten degree days on the slopes, to chilly July evenings in the mountains, this jacket has proven to be worth its weight in gold. The Mammut Mercury jacket is a lightweight fleece jacket with a low-profile hood, good looks, and zippered hand warmer pockets. It is great either layered or by itself.

Mammut 1Pros

  • The jacket is VERY soft. Even after several months’ worth of trips through the washing machine, it’s still soft.
  • The low-profile hood is warm and soft and it will also fit under a helmet. When the jacket is fully zipped up, the hood sits close to your face and will not blow off in a stiff wind.
  • Fleece is naturally hydrophobic— meaning it naturally sheds water. On a Tenkara fishing trip, the bank I was standing on collapsed and I fell into deep water. I was wearing my Mammut Mercury jacket, which got soaked. However, after ringing it out and an hour in the sun, it was dry.


  • This is one good-looking jacket. My first one was stolen off the back of my seat in a restaurant when I went to use the restroom. Don’t let yours out of your sight.

Mammut 2The Mercury Jacket by Mammut is a great multi-use jacket. It is light, packable, and most importantly comfortable. If you are looking for a lightweight jacket that can double as a base layer for cold winter days, but that is still perfect throughout the year, the Mercury could be exactly what you are looking for.
