The Warmfront is a chest warmer.

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.

You don't have to be an athlete to wear a Warmfront - you just need to be cold!

Inspired by the Norwegian concept koselig - a sense of warmth, kinship, comfort and "cozy", the Warmfront Koselig chest warmer will be your trusted companion in the dark snowy winter. More windproof 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, walking the dog.

If you are cold, the Warmfront Koselig is going to help.

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 second layer.

Wind resistant warmth for winter weather.

So Excited to try this

Warmfront Koselig Chest Warmer for Women

My wife complained about having a cold chest whilst cycling, I found this on a cycling website. When I tried to buy some they weren't available in the UK. Contacted the US suppliers and got a nice reply from Matt Sodnicar, a few days later I was able to order them and Elena is now a lot warmer and happier... Excellent product, thanks for the great service!

Warmfront Koselig Chest Warmer for Women

Bought this for motorcycle riding and it works perfectly. As a passenger, sitting behind and a bit higher than my skinny husband, I get pretty battered by wind and the warmfront chest warmer makes a huge difference without adding any bulk. It greatly helps the wind and keeps me toasty warm on those chilly fall rides. So glad I purchased it and would absolutely recommend it to everyone. Thanks you

I now own 2 warmfronts. This one is warmer than my other one. I love them both and especially appreciate this Koselig version, which I have predominantly used for cross country skiing this winter. It is remarkable that by wearing this warmfront, I am able to eliminate an entire additional layer I would otherwise wear. I highly recommend adding one to your collection for cycling, hiking, skiing, whatever outdoor activity that you engage in. It is lightweight and packs down to smaller than a ski sock folded up...so easy to put in your pocket if needed.

Warmfront Koselig Chest Warmer for Women

Yeah I'm writing a review for the women Ultralight chest warmer and no I am not a woman, but I'm 5'4" and 120lb so there. If you are a small guy, the fit is spot on. But as a small guy living in a tropical country I do run cold and I found the Ultralight a little bit too breezy for my liking, my rides start at 5,000ft and 55F and at this temp I could feel the wind cutting right thru me with little to no warming effect from the fabric. This fabric does a couple of things extremely well, it breaths and it's highly compactable. But I do love the execution and concept of the Warmfront chest warmer, so I order the warmer Koselig as I think that would be the ticket for me. In the meantime I will continue to use the Ultralight when my rides start above 65F as it is perfect for me when it's not really "cold" but I want a bit of protection or if I go mountain biking where wind is not a factor.

Tired of being cold or too hot on a ride?
Carry too much gear?
A Warmfront keeps you warm without overheating.

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.
