The Warmfront Koselig is a wind resistant chest warmer for winter weather.

It is a thermal, one-sided bib / base layer to insulate​ your core from the cold wind.

We designed it with a velcro collar that lets you put it on and take it off quickly.

Inspired by the Norwegian concept koselig - a sense of warmth, kinship, comfort and "cozy", the Warmfront Koselig chest warmerwill be your trusted companion in the dark snowy winter. More windblock and waterproof than our original - but not any thicker - the Koselig is ideal for winter fatbike and CX rides, snowshoe trips and the ski lift.

Perfect on its own between 30-40F/ -1-4C as your first line of defense. Below freezing, we suggest wearing a thin baselayer and the Warmfront as your firstlayer.

Warmfront Koselig Chest Warmer for Men

Easily portable, goes on and off without having to get undressed. Adds just enough warmth to the chest and stomach without adding extra material to my back, which I don't want any extra material on so the sweat/body heat can more easily escape. I also like the neck collar to help keep cold air off my neck. I should have gotten it about 4 inches longer so the it could also cover my stomach which often gets very cold.

One of the best investments I have made. I am so glad to have found you. It kept my core warm from the elements (wind). The fabric didn't weigh me down. A really neat design to put on and take off. Thank you :)

Warmfront Koselig Chest Warmer for Men

I use the Warmfront for road cycling and it works well. I particularly appreciate that it's compact and can easily be removed and stored in a jersey pocket if needed. It really provides options on long rides when the temperature can fluctuate. My only gripe would be the neck strap. The velcro is a bit rough against bare skin, but I can usually pull up my other collar to ease any issues. Matt at Warmfront provided excellent customer service when I had a fit issue. In my experience, they are a great company that cares and listens to their customers. I will be a repeat customer!

Warmfront Koselig Chest Warmer for Men

Got my Warmfront Koselig and tried it out the next day. I will be honest and say that I dress in layers and didn't really expect the Warmfront to the the "Be all to End all. It DOES do what I expected it to. That is to keep my core warm, even on a 25 m. ride, in the mid 2O's, while riding my E-bike at 20mph- into a 15-20 MPH wind! Those are the kind of conditions that will cool you to the core, but not with a Warmfront Koselig! My Koselig will become part of my "go-to Cold weather kit" anytime temps drop below about 45 degrees, mostly because it's the one pc. of kit I kNOW will keep my core warm. If it's too warm, I can always unzip my jacket or whatever other layer I'm wearing. Do yourself a favor and get a Warmfront!

The Warmfront | Men's Collection | Extreme Cold Chest Warmers For Men

Versatility, simplicity, affordability.

​Because the Warmfront covers only your chest, your back won't get as sweaty.

When the conditions improve - the Warmfront rolls up smaller than a vest to stash in a pocket. ​And when conditions get bad, you can put it on easily without removing your helmet or your pack. Great for all kinds of outdoor pursuits from cycling and skiing to hiking, and running. ​


The Warmfront is technical fleece to block the wind and keep you warmer. The Velcro collar lets you easily take it off when you're warm, and put it on when you're cold. Rolls up small as a pair of socks. You'll be warmer without overheating and wearing too many layers. Specific men's and women's designs.
