Norrøna Senja Warm1 Hood Men's is a lightweight, quick-drying mid-layer designed for trail running and other outdoor activities.

The main material is a lightweight warm1 fleece fabric that is durable, quick-drying and warm. A lighter material is used on the back and under the arms for increased moisture transport. Both materials are treated with HeiQ Fresh FFL for odour control. This is a bio-based sugar polymer that is free from silver and is not antimicrobial. It removes fat and protein from sweat, thereby eliminating the basis for bacterial growth and reducing odour.

The jumper has a technical fit with an anorak zip at the front and a fixed elastic hood with a close-fitting construction. Further details include a zip chest pocket, cuffs with thumb holes, flatlock seams that do not chafe, and reflective details.
