DESCRIPTION
The Mammut Lenni Shirt is a hiking shirt designed for those seeking a reliable garment for both day trips and multi-day journeys. With the latest version, Mammut has updated the material while retaining the features that have made this model one of the most popular in its category: lightness, breathability, and easy care on the trail.
Materials and Construction
The fabric is made from 91% recycled polyester, a choice that reduces the garment's environmental impact without compromising performance. The high-performance material ensures good moisture management, drying quickly after physical exertion — a crucial feature during long stretches or in the typical climatic variations of high-altitude hiking.
Versatility in Motion
- Cut designed for ample freedom of movement even with a backpack on
- Suitable for variable climates thanks to its low weight and breathable fabric
- Easily combined as a base layer or as a standalone item in mid-altitude seasons
- Practical for travel: takes up little space in a pack and requires no special care
The Lenni Shirt is aimed at hikers who want a no-compromise trekking garment: lightweight, functional, and made with low-impact materials, suitable for both a day in the mountains and itinerant trips where every gram in the backpack counts.
