Mammut - Aenergy ML Hybrid Hooded Jacket - Fleece jacket

Polartec Alpha keeps you warm and lets air through

The Aenergy ML Hybrid Hooded Jacket from Mammut combines Polartec Alpha as active insulation, which reliably keeps you warm whilst mountain touring and ensures excellent breathability at the same time. The stretchy fleece supports your freedom of movement and helps maintain a comfortable temperature even when your pace changes. Thanks to its lightweight design of around 350 grams, it is barely noticeable in your rucksack and is a versatile hybrid fleece jacket.

Keep the wind at bay and carry everything you need

The full-length front zip makes it easy to put the jacket on and take it off, or to provide quick ventilation when needed. The elasticated hood, hem and cuffs fit snugly to keep draughts out. You can safely store small items in the two zipped chest pockets, keeping them within easy reach whilst on the move.

Regular fit for versatile wear

Designed for mountain use, this jacket has a regular fit, so you can wear it just as easily as a mid-layer or on its own. As a Swiss outdoor and alpine specialist, Mammut has been creating thoughtfully designed gear for over 150 years — and this model is no exception.
