On a recent trail running trip in Grand Teton National Park, the Mammut Kento Light HS Rain Shell was my go-to piece for the chilly morning starts and the afternoon rain showers. This versatile piece was ideal for these trail adventures, but I’ve also tested the Kento Light while hiking and mountain biking. It’s extremely lightweight and compresses into a sack the size of my fist, all while maintaining important technical elements. The Kento Light is waterproof (with a 100-percent Polyurethane membrane) and still breathable, providing weather protection even within its minimalist and compressible design.
Since the hood has a more rigid structure than the rest of the jacket (as it’s intentionally reinforced) this is the only piece of the shell that takes an extra few moments to compress down. I was able to quickly stuff the jacket in my running vest after I warmed up in the morning and then pull it back out again when it started to rain on our afternoon descents, but I have also enjoyed using the stow bag to make the packing volume even lower. I keep the stow bag in the concealed chest pocket on the front of the jacket — the same place I often secure my phone since this compartment has a water-repellent zipper.
There’s nothing complex about the sophistication of the Mammut Kento Light HS Rain Shell, and that simplicity what makes it ideal for all types of mountain adventures. Coming out in Spring 2020, this piece is meant to be a three-season staple for outdoor recreation and a year-round go-to for travel.
