Use & Highlights

When to use — Stop-start activities. Trekking, climbing and skiing in variable conditions as a midlayer under a shell or standalone in dry cold. The hoodless version of the Asger — removes the hood for a cleaner profile under a helmet and reduced bulk under a hardshell.

Polartec® Alpha™ — What makes it different? Originally developed for Special Forces use, Alpha is engineered for stop-start activity where a standard jacket would either overheat on the go or chill on the rest. It actively exchanges air as effort levels change, eliminating the need to constantly add and remove layers.

NetPlus® outer — 20D outer woven from Bureo® NetPlus® reclaimed fishing nets. Windproof and water-repellent with a C0 PFC-free and PFAS-free DWR finish. More demanding recycled source than standard recycled nylon.

Alpha-lined collar — The Polartec® Alpha™ fleece extends into the collar, eliminating cold spots at the neck without adding a separate layer.

Weight — 249g. Stows easily in a pack.

Ethics & sustainability — 100% recycled Bureo® NetPlus® outer. PFC-free and PFAS-free DWR finish.

Excellent

Perfect jacket for hard work in autumn and spring, and great for layering in winter. Keeps the wind out and dries so quickly. I really like that this version has no hood.

ASGER HS JACKET.

I have 2 of these jackets and they are brilliant. Far superior to my Arcteryx items.

Sizing odd and seems flimsy

Big fan of Jottnar products but some consistency in sizes across the range would be much appreciated. Jacket fits very small and I had to go a size up, could’ve even gone up two sizes dependant on whether using as mid layer or pull on sweater. Not used in the wild yet where I hope brand quality will prevail but it does seem very flimsy and not worth the premium paid compared to their other products I have purchased

Asger HS

I am lucky enough to have a selection of Jottnar’s great gear, love it all! The Asger is such a versatile item, and has been my go to mid and top layer for the last 18 months. I bought two when I could! I recently bought the Asger HS in the same size (M) but found the fit quite a bit smaller than the hooded version, so had to go up a size. The fit isn’t as good for me, but there again, I’m not built like a Royal … It’s well made, light, packable and just as warm. Shame the sizing has changed, otherwise it would be a five star. Don’t be put off, just try it and get the size that fits, you won’t regret it. Customer service is fantastic too.

Great for day bag

A great product, great quality and very lightweight, good to go in your rucksack when you don’t need it right away.
I did initially go for a medium but ended up sending back for a large, no hassle, and large is a good fit, not too snug but not too big.
Definitely recommend this jacket.
