Like it's not even there.

Striking the ideal balance between an insanely small, lightweight pack size and exceptionally protective features, the Mountain Equipment Men's Impellor Jacket is most at home racing over technical ridges and scrambling up and down peaks in a day.

Waterproof, breathable protection in a lightweight package comes to you courtesy of the Gore-Tex Active 2.0 fabric, defending you from rain, sleet, and snow while allowing internal moisture to escape, all without hindering your ability to move quickly. This minimalist alpine jacket is also equipped with a Mountain Hood that features an internal wicking barrier and rear adjuster for a sweat-free, customized fit, as well as articulated and pre-shaped sleeves that tailor towards a fast-paced and free range of motion. Tipping the scale at a meager six ounces, the Impellor comes standard mesh stuff to ride along without being noticed until you need it the most.

Unbelievable Goretex Jacket!

  • Familiarity: I've used it several times
  • Fit: Runs small
  • Size Bought: large

This jacket is perfect for those of us hate bringing rain jackets. This jacket stuffs down almost to the size of a Patagonia Houdini! Which is ridiculous since this is a fully waterproof Goretex shell! It's perfect for afternoon showers, or when you're uncertain about the weather. It doesn't have a lot features, but it keeps you dry and takes up the volume of a tennis ball in my pack. This jacket will now go from my backpack to rolling luggage to glove compartment..... basically everywhere me. It's an athletic fit so size up if you are borderline.
