Get three soft, stretchy braided bands in one pack, each with a sliding buckle so you can fine-tune the fit. The breathable woven strap slips on easily, and quick-release pins fit 20mm and 22mm COROS watch lugs.
the clasp regulating length is too loose, so it does not tighten properly and the strap slips out easily. it needs to be tighter so it actually stays at the chosen length. the strap length itself is huge for female wrists and almost doubles up fully when worn - any bigger and it would slide off from my arm. I have to tighten it almost the full way to the other side of watch, it looks ridiculous
