Bottom Line:

Recently I had the opportunity to use and test out the Mammut Kento HS jacket during a few coastal hikes in Ireland dealing with rain and ocean spray. My first thoughts when I started using it was that it’s pretty light to carry (Size Medium weighs 400gs) and also a lot more stretchable than I’m used to with waterproof shells.

The stretchable feel of the Kento HS jacket comes from the proprietary Mammut material called DRYtech™ Premium. It functions much like Gore-Tex, letting sweat vapor pass through the material while stopping any water droplets from penetrating it. In my experience I found this to be true.

I found the sizing of the Kento HS jacket to be athletic or trim fitted for the size. This has been common among other European technical clothing brands that I’ve used. If you like a looser or more “expedition” fit then consider sizing up.

When rolled up inside it’s hood it is very small and compact (approximately the size of a Nalgene bottle). The Kento HS jacket would be perfect to leave in the bottom of your pack on days when the weather is fluctuating. At only 400gs, even if you don’t end up needing it, it won’t weigh you down.

The Kento HS jacket has two hip pockets and one outer chest pocket as well as two armpit vent zips. There are adequate options for cinching the hem and hood down to stop wind getting in without adding bulk or weight. The velcro cuffs on the arms ensure that wind can be kept out through there also.

Overall the Kento HS is an excellent jacket to take with you to wild places that excels at being lightweight and packable.

  • Weight: At only 400gs, the Kento waterproof jacket is light which makes it versatile for a number of situations.
  • Packed Size: Packs down really small due to the thin DRYtech™ Premium fabric used.
  • Cost: For a feature rich jacket that’s wind and waterproof it is very reasonably priced (At time of writing: <US$140, <CA$190)
  • Comfort: The stretch in the material limits any real constrictions while wearing it. The cut and fit is also contoured to the shape of the torso.

  • Pocket: I would have liked to have seen an interior chest pocket.

Buy it if:

You are looking for a lightweight, packable hard shell for protection from all kinds of bad weather. The Kento can be used as simply an emergency shell in the bottom of your pack or a daily use rain jacket.

I grew up in County Dublin, Ireland and moved to British Columbia, Canada with my wife in 2010. I fell in love with being in the Backcountry and Mountains that are all around me here and try to spend all of my free time exploring those wild places. My main goals are to chase happiness, see as much of this planet and its cultures as possible and grow every day through knowledge and experiences.
