Asta Lightweight Down Gilet – Jottnar

Description

Lightweight down vest with high warmth-to-weight efficiency for cold-weather layering and everyday wear.

850 Fill Power DownTek™ hydrophobic goose down at a 93/7 ratio, in a Pertex® Quantum Pro outer woven from Bureo® NetPlus® reclaimed fishing nets. Updated for 26 with narrower baffles, a grown-on collar and raised zipped hand pockets. Stows into its own hand pocket and weighs just 258g.

When to choose a gilet and why the Fill Power grade matters — is in the details below.

Our ethical approach complies with the Responsible Down Standard. Our hydrophobic down uses bluesign®-approved clean chemistry.

When to use— Core warmth layering under a shell on cold mountain days; equally useful as a standalone piece in mild conditions or for everyday urban use when a full jacket is too much

The case for a gilet—By removing the sleeves, the Asta concentrates insulation at the core — where heat retention matters most. It also breathes better than a full jacket during high output activity

Weight and packability.At 258g, the Asta stows into its own hand pocket; expedition-grade fill in a piece that disappears into a pack or bag

850 Fill Power—The same expedition-grade DownTek™ hydrophobic down as the Fenrir; 93/7 down-to-feather ratio and molecular-level hydrophobic treatment means the fill retains warmth when damp rather than collapsing.

NetPlus®— Pertex® Quantum Pro 30D outer woven from Bureo® NetPlus® reclaimed fishing nets, fully traceable to source. Windproof and highly water-resistant with PFC-free DWR.

2026 updates— Narrower baffles for improved warmth and compressibility. Grown-on collar removes the seam at the neck for a cleaner fit and better cold-weather sealing. Raised zipped hand pockets are positioned higher for use under a harness.

Ethics and sustainability—Responsible Down Standard compliant; bluesign®-approved clean chemistry and PFC and PFAS free throughout.
