Like cuddling next to a roaring fire.

Slip into the Mammut Men's Phase Fleece Jacket for levels of warmth and coziness usually reserved for evenings sipping hot cocoa next to a roaring fire. This fleece jacket is ideal for layering under your favorite shell when skiing, snowboarding, or winter hiking. Fusing a warm and robust Pontetorto Tecnowool exterior with a soft and cozy polyester fleece interior, this fleece jacket wicks moisture from the interior polyester and transports it to the wool surface where it can evaporate. Ultimately, this exceptionally warm and cozy midlayer fleece keeps you dry when sweating and exercising, and it's incredibly stylish for après ski parties and happenings.

  • Warm, robust Pontetorto Tecnowool outer material
  • Soft polyester fleece on the inside
  • Two zippered hand pockets, one zippered chest pocket
  • Flatlock seams for added elasticity

Great product, odd fit.

  • Familiarity: I returned this product before using it
  • Fit: Runs large
  • Size Bought: XL

Really well constructed, and felt very warm and cozy. However, the sleeves were just too long, and seemed to fit incorrectly.
Also, the zipper was on the wrong side. Sorry, pet peeve of mine. Thought the grab side of the zipper was suppose to be on the right hand for male clothing.

Quality construction, soft & warm

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: XL

Pros: Warm, soft, quality fabrication. Deep inside cloth pockets. Long sleeve length (~36-37") Great deal on sale.
Cons: Tiny outside pockets (barely fit my hands inside) Oily burlap odor until your first wash.

Bought this for cooler weather to wear by itself and it doesn't disappoint. Very warm by itself. You could wear this under a heavier jacket also due to its hugging fit. Actually more of a sweater than a jacket in my opinion but that's exactly what I thought it would be. Great fit for an XL (I am 5'9", have a 45" chest, 34" waist), and the material is very soft and comfortable. Great combination of wool and fleece. I've gotten several compliments on the fit and the color (green]. The athletic fit will hug your body type so if you are in shape then this is for you. Overall very pleased I bought this and looking forward to many years of use with this.
