Is it a shirt? Is it a jacket? It's a Jack-sey! A Jack-sey is perfect for temperatures in between a shirt and a jacket.
Overcome the gap between a shirt and a jacket
Spring, autumn or the warmer days of winter. Deciding exactly what to wear can be complicated. With a Jack-sey, this problem is a thing of the past. At the front, the Gore-Tex Infinium protects you from the wind. The FLY SL outer layer is water-repellent and ensures that light rain or splashing water won't bother you. The Clima SL insulation is perfect for the tricky temperatures of these times of year. It keeps the cold out without being too hot.
On the back there are three back pockets where you can carry food or spare parts, as well as a fourth zipped pocket where you can carry any valuables. The YKK VisIon zip at the front opens and closes easily so you can operate on the bike. Silicone grippers at the bottom keep the Jack-sey nicely in place. The Jack-sey also has reflective details that make you more visible in bad weather or twilight conditions.

Great lightweight jacket, warm and close-fitting
- Per 30 May 2025
Fantastic light jacket, warm and close-fitting, very happy that the zip can be opened from the bottom, because when it gets sunny and 13-15 degrees it's nice to be able to zip up a little, it's very breathable, but to get all 5 stars, it needs to be a little more breathable, then it's perfect
