Mammut Taiss Light ML Hoody
Review by Kate Agathon
Ever since I got my first Mammut midlayer hoody (the Runbold) circa 2018, I’ve been a loyal fan of Mammut midlayers for their overall construction and style.

Therefore, I was pleased that for 2025/26, Mammut continues its tradition of functional and attractive midlayers with the Mammut Taiss Light ML Hooded Jacket.
Ideal for shoulder season in the mountains, the Mammut Taiss Light ML Hooded Jacket is great to wear anywhere- mountain biking, hiking, walking the dogs, to the gym.

I liked the streamlined minimalist design that is longer and practical; not the short, boxy trend currently saturating the outdoor retail apparel market. True to size, the athletic fit was not too confining and not too loose.
I appreciate the practical features (ponytail holder and thumb holes) and flat seam design to optimize comfort underneath a backpack or outer layer. The hood featured an elasticated border and fit neatly underneath my mountain bike helmet. In short, it was extremely useful for mountain biking.

What makes the Mammut Taiss Light ML Hooded Jacket superior to the old Runbold is that its fabric is stretchier, doesn’t bulk up (easy layering!), and has a zipper.
In recent years, my layering preferences have changed and I’ve swapped out pullovers in favor of the more practical full zippers. It’s just easier to add or remove layers and avoid the hassle of having to remove any helmets, hats, sunglasses, etc. while doing so.
Zippers serve such an essential function while outdoor recreating. Being able to easily layer up and also adjust for my comfort level for different sections of my ride was important. Am I approaching a steep section? Unzip!
What I liked the most about the Mammut Taiss ML Hooded Jacket are the pockets. Not only does it have two exterior concealed zippered pockets with pulls to keep essentials safe, but it also has two spacious interior pockets where I can stash my eyewear.
Other features:
- Lightweight, comfortable, stretchable material
- Robust fabric thanks to polyamide content
- Regulated moisture-wicking prevents rapid overcooling
- Very good warmth-to-weight ratio
- Functional underarm gusset for optimum freedom of movement
- Flat seam design for a high level of comfort and to avoid chafing under the backpack
- Mammut logo on left sleeve and wording on right chest and center back
- Durable, 4-way stretch
Responsibly constructed from polyamide, polyester and spandex, the Blue Sign-approved Mammut Taiss Light ML Hooded Jacket is built to move.

On chilly days when the weather turned and I didn’t have any gloves, I was thankful for the thumbholes that kept my hands warm while walking the dogs. They’re also nice to have when using this as a midlayer and preventing the sleeves from getting bunched up.
I appreciate that Mammut has retained its outdoor heritage and has not integrated a lot of fast fashion in the design of its clothes. Why? Because I want something functional built to wear for outdoor recreating that I will keep for years to come- not just a season.

The Mammut Taiss Light ML Hooded Jacket is available in sizes XS to XXL and six colors. Overall, I really like the Mammut Taiss Light ML Hooded Jacket for its functionality and stretch properties. I look forward to wearing this in upcoming months as an outer layer for nordic skiing and as a midlayer for alpine skiing.
