A light jacket that keeps you warm in cold and wet conditions


Technical assessment





Warm capacity








I felt all excited when the package arrived at my doorstep: finally, I would get to try this new jacket that I had heard so much about. The first feeling when touching the piece was that it actually feels like down. The design is cool, has a nice female cut and comes in several different colours. It has internal elastic cuffs, which stop the wind from getting inside. It also has two hand pockets with zips and a hem cinch cord.

So, what’s Thermoball? It’s a new synthetic alternative to down and I guess the main plus is that even though it gets wet it continues giving you warmth, contrary to down. The synthetic insulation traps the hot air which increases the warmth, reducing the loss of heat. It’s also highly compressible, which allows you to fit it in a small back pack when you’re out in the mountains.

I think it’s very comfortable to wear and with its active fit it allows you to move freely. I have used it when climbing in the mountains of Picos de Europa in Spain scrambling, climbing and belaying and it has allowed me to have the mobility I needed. As already commented, it’s easy to store since it doesn’t occupy any space so it’s a must-bring to any day out in the mountains, where the weather and temperature can change in a split second. I haven’t had the possibility to try it in very low temperatures, but it works just fine for days around 5-8 ºC. When it rains a lot I just wear it under a waterproof shell. It’s also nice to bring to put on after training on those days that you aren’t able to shower directly afterwards, avoiding to get cold.


What I mainly miss in this jacket is a hood, though there are other models that have one. I would also have liked some inner pocket to keep a key or the mobile phone.

This is a jacket for active people who look for an alternative to the light weight down jackets. It’s also suitable to wear as a street jacket because of its fine design.

*Comfortable and allows free movement
*Keeps the warmth even when it’s a bit wet
*Nice design and fit
*Light and easy to store

*Takes a bit more space than a down jacket of the same characteristics
