For the windy days on the wall.

The Mammut Men's Ultimate Hooded Softshell Jacket utilizes a Gore Windstopper membrane for excellent wind-resistance and breathability while you're climbing. Articulated elbows ensure a full range of motion whether you're sending or belaying, and underarm zippers provide the ventilation and airflow your hard-working body needs. Mammut also added an adjustable hood, pre-shaped thumbholes that stay closed and out of the way when not in use, two side pockets that are always accessible even with a harness or backpack on, and an internal media pocket to protect your phone.

  • Gore Windstopper softshell (3-layer)
  • Articulated elbows
  • Underarm zippers
  • Adjustable hood
  • Pre-shaped thumbholes
  • Two harness- and pack-compatible side pockets
  • One internal media pocket

Update on 7/22/2015:The hood is not large enough for complete helmet compatibility. Very tight when I zip it up entirely. So I adjusted it from five stars to four stars.
Love everything about this! Deep waist pocket for goods and hand warming. Convenient chest pocket for cellphone. Two way zip for harness and belaying. Other zips for quick warmth release. Very wind proof. Hood enough for hamlet but not too large, right on size.

How does the fit and warmth compare to that of the Gamma MX?

I don't have the Gamma MX, but did try out the Gamma MX prior to getting the Acto MX. I would say that the Gamma is warmer than the Acto, and the Acto is pretty comparable (maybe even slightly warmer) than the Mammut.

The Mammut's fit, at least to me, seems more athletic than either.

Best Answer

I have both the Mammut Ultimate Hoodie and the Gamma MX (non hooded) jacket. The big difference between the two is the Gamma doesn't block wind as well and therefore may be not warm enough on windy cold days. Also the Gamma has a light fleece backing whereas the Mammut is strictly a shell, no insulation. I find the Mammut to be extremely versatile with the pit zips so if wind abates you can just open it up a bit for better breathability. My Mammut is my primary winter shell.
