The flexfit Delta cap ByOky has a sporty casual look and consists mainly of polyester and partly of elastane. The cap is extra flexible and fits like a glove on your head because of the stretch fabric, which is handy for 'work' as long as you don't lose it. The cap is Oky's favourite and made of high-tech material and has an antibacterial technology with a quick-drying anti-stain layer. Oky's motto 'Never lose your hat' is delicately embroidered on the back. There are no seams on the inside and it features Oky's signature. Flexfit Delta is made with minimal loss of material, waste and energy.
