Very Happy Jersey
Featherweight, high-compression jersey engineered for ultimate speed, pro-level performance, and second-skin comfort. Inspired by our Echelon line jerseys.
Inspired by the pure joy of our Planet Isadore Roadshow, the Very Happy Jersey captures the feeling of summer rides filled with laughter, friendship, and carefree moments. Designed as a reminder that the best rides, just like the best memories, always come with a smile.
Crafted with two high-performance fabrics, it combines a micro-perforated woven torso for optimal breathability and moisture control, and aero-channeled woven sleeves and shoulders for cutting through the wind with ease.
Every detail is made to perform — from narrow hem tape to the ultra-light YKK® NATULON® zipper. This jersey brings together the best of our Echelon Aero and Ultralight pieces, upgraded with recycled materials and a precision-focused, aerodynamic fit.
Featuring medium to high compression, a shorter back and torso, and longer sleeves, it stays put and performs under pressure.
Proudly made in the EU.

Great racy aero jersey! I'm 1.83m and 79kg and I wear it in size M for a tight and racy fit. Quality is always great when you buy Isadore ????????Show full review
