I’m always looking for a jacket to throw into the do-it-all category. The updated Mammut Teton Jacket is reasonably lightweight, stormproof, and the breathability of the GORE-TEX 3-Layer membrane is superb. I’m confident I’ve found my four season hardshell. I’ve gone through a multitude of jackets over the years and each of them served a specific purpose, yet I rarely ran into a piece of gear that worked for all four seasons.

Some jackets are crazy lightweight, but full storm protection and durability can be an issue in the long run. Some jackets are more heavy duty, but weight and high exertion activities can slow you down and make a sweaty mess of things. The Mammut Teton Jacket sits right in the middle.


Colors Available: The Teton Jacket comes in red (inferno), black (shown), and yellow (salamander).

Sizing: The Teton Jacket comes in S -XXL. Mammut lists the Jacket as having an athletic fit and I definitely agree. I am 5’9″, 170 lbs and wear a medium. I have enough room to layer a lightweight puffy and long underwear underneath. I recommend going one size up if you live, work, or play in a very cold climate and want to wear multiple layers underneath.

Weight: My medium weighs in at 445 grams (15.7 oz.). As stated before, it’s definitely not the lightest jacket on the market. For general outdoor use in a variety of condition, the few extra ounces and weather protection are worth it.

Material: GORE-TEX 3-Layer

Suited Activities: I have found the Mammut Teton Jacket works great while backpacking, skiing, climbing, during windy conditions, or anytime the weather turns south. On Mount Shasta we skinned up about 5,000 vertical feet. The jacket was perfect during the second half of the ascent and descent as the temperatures dropped and the wind picked up. I though I might get sweaty, but the GORE-TEX membrane did its job and I stayed dry and comfortable. The last thing you want to do is get wet in the backcountry. The probability of further injury increases if you are already wet when an unfortunate accident happens.

  • Long sleeves and the arms stay in place when reaching

  • All zippered areas have dual zippers
  • Tight waterproof zippers


  • Price
  • Pit zips – I like them, but I know this can be a deal breaker for some. For most people, you either love them or hate them
  • Zippers are tight and waterproof, but very hard to manipulate with one hand
