Vegan microfiber strap, PVC-free and biodegradable.
A smooth, even surface gives the 100% animal-free Sustain a clean, compact look with a subtle grain that reads close to leather. The padded shape adds some volume through the center without becoming bulky. Made in Italy, it is part of ColaReb’s vegan lineup.
The strap is made from ultra microfiber fabric with a fine, compact structure. It has a soft, flexible feel while remaining resistant to daily wear. The material is breathable, fully vegan, and free from PVC and harmful substances. It is also biodegradable.

Sustain's lightly padded build creates a slightly raised profile through the center while keeping the edges low. It sits securely on the wrist without adding excess bulk.
Length & wrist size:
If your wrist sits near the overlap between sizes, either length can work. A shorter strap reduces tail and positions the buckle more tightly, while a longer strap provides more room and tail.

ColaReb is an Italian watch strap manufacturer based in Rome, producing leather and microfiber straps since 1990. The brand works with small family-run workshops where edging, stitching, and color preparation are completed by hand, with all straps designed and made in Italy using Italian materials. Natural variation in grain and color reflects this approach and the materials used.
