Redesign 2026

We read your reviews. We rebuilt our jerseys.

Fabric too thin, misprinted letters, sizes running small: you told us, so we went back to the drawing board. To celebrate, 10% off the whole store.

02 · What we changed

Three problems, three fixes

105 g140 g

A thicker fabric

Our jerseys go from 105 g to 140 g fabric. Denser, it holds its shape and hangs better. Our workshop has been making it since late October.

SLUEBLUE

Printing checked letter by letter

“Sluelock” and “Karser” came from a faulty batch this summer. The designs were fixed at the source: since September, you’ve been confirming it’s solved.

XXS6XL

Sizing made clear

Close, football-style fit, and one rule everywhere: between two sizes, take the larger one. XXS to 6XL, with a size guide on every product page.
