Garmin Fenix 5S,5S Plus,6S,6S Pro,D2 Delta Replacement Bands Strap Quickfit (20mm)

Yes — this is a 20mm QuickFit replacement strap made to fit the Garmin Fenix 5S, along with the Fenix 5S Plus, 6S, 6S Pro (including Sapphire) and D2 Delta S. It clicks straight onto the same QuickFit 20mm mount with no tools required. The strap suits wrists of around 140mm to 200mm, with a 110mm long side and 75mm short side, plus an adjustable buckle for a secure, tailored fit.

It's made from soft, flexible silicone that stays comfortable for all-day wear and wipes clean easily. Key features include genuine-style QuickFit 20mm clips for a tool-free swap in seconds, an adjustable buckle, and a choice of 10 colours — including a Black 3-Pack — ideal for refreshing your look or replacing a worn or torn strap. As a premium aftermarket band, it delivers the fit and feel of the original at a friendlier price.

Yes. The lightweight silicone and secure QuickFit lock make it a great everyday choice for runners, gym-goers, dog walkers and daily step-counters. The wipe-clean surface and snug buckle also suit tradies and construction workers, nurses and healthcare staff on shift, office professionals, retirees and grey nomads, and travellers wanting a hard-wearing spare. Brighter colours are popular for weekends and the outdoors, while black and navy keep things professional at work.

Not sure which model you own? The quickest way is to flip the watch over — the exact model name is printed or engraved on the caseback. You can also check Settings > System > About on the watch itself. The Fenix 5S, 5S Plus, 6S, 6S Pro (and Sapphire) and D2 Delta S all share the smaller "S" case and the same QuickFit 20mm fitting, so any of them works with this strap. The "Plus", "Pro" and "Sapphire" labels refer to features and glass — not band size — so they all take 20mm.

This strap is designed specifically for the Fenix 5S-family "S" watches that use a QuickFit 20mm mount. If you check the caseback and find you own a larger full-size Fenix or a newer-generation Garmin, it will need its own correctly sized, model-specific band. To get the right fit first time, identify your exact model and then browse the matching model-specific Garmin collection for your device. Still unsure after checking?
