November 2025: ASSOS end of production sale item.
Limited sizes/quantities available.
LIMITED EDITION. The ASSOS x Mammut Aenergy IN Hooded Jacket is an 850-fill down puffer that packs big warmth into a packable, go-everywhere design.
Ultralight and packable with cold-weather protection, this jacket is made in collaboration with Mammut for gravel bikepacking. Responsibly sourced, hydrophobic, 850-cuin-fill-power Mammut DRY DOWN is placed in small chambers of the Pertex® Quantum outer fabric for evenly dispersed warmth, while a PFC-free DWR finish defends against light precipitation. A 2-way front zipper allows for a versatile fit. As an extra-warm outer layer or a small-packed thermal backup in a bike bag, the ASSOS x Mammut Aenergy IN Hooded Jacket provides lightweight insulation without compromise.
Please note that the sizing on this item is a relaxedFit that provides extra room for layering comfort.
