Great quality and looks amazing. Feel like same strap as OEM rubber single-pass.

The strap is comfortable. It is thin and flexible, yet feels very sturdy. The length fits my 7.5in wrist nicely. My only suggestion, would be to add some ventilation holes, so it's more like a tropic style strap. It can get a little sweaty between the strap and my wrist in hot/humid weather.

Definitely recommend for those who have a thicker watch that’s top heavy there aren’t many options out there that allow you to wear something beside a bracelet without adding a good amount of height and presence to your watch. Some straps add so much height that it feels like the watch head is on a pedestal which is then sitting on your wrist. *Enter Anchor Strap Single Pass FKM* this strap adds virtually little weight, enhances the overall look of your watch, very durable and soft. Some rubber straps have given me skin irritation but this does not. It’s hard when you’re excited about a strap only to find out that it just doesn’t feel as premium as you thought, the straps by Anchor Strap feel as good as they look.

The strap is very nice but just isn’t as nice as the AnchorFlex Pro strap. If you are between the two styles definitely go for the Pro!!
