Use & Highlights

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.

Cracking bit of kit

Believe it or not we’ve had some chilly mornings up here in the northeast and this body warming is perfect for chilly mornings walking super light and perfect fit thank you jottnar

Perfect lightweight layer for UK conditions

Really impressed with this vest. Bought it to layer under a shell and it works perfectly with no bulk but still keeps my core warm. Also great on its own over a T-shirt for typical UK spring and summer days. Fit is spot on, I went for a small and it’s fitted without being restrictive. Comfortable, lightweight, and I end up reaching for it all the time.

First time purchase

To be honest I'd never heard of or seen Jottnar clothing until I saw one of the Sky television reporters wearing a Jottnar jacket.
However I decided to purchase a Gilet from last year's collection, so glad I did, without doubt the warmest Gilet I have ever owned.
Will definitely purchase other goods in the future.

Great kit

Best Gilet I’ve owned quality is top notch

Quality product, Quality Service

An excellent piece of kit - smart, comfortable and very warm - all you would expect from Jottnar. I have made several purchases from Jottnar and the quality of each has been outstanding. Similarly the service received has been exceptional following a couple of mistakes made by myself when ordering. The queries raised were resolved swiftly, without any fuss and the necessary changes accommodated immediately.
It really felt as if my custom was appreciated and the service received has been second to none. Very grateful for both the quality product and equally good quality of service. Cannot recommend them highly enough.
