Rugged Band - 46mm/49mm | 黑色金屬件 | 黑色

I was skeptical about the metal hardware on a band meant for swimming, but the stainless steel lugs have held up perfectly through saltwater sessions. The FKM rubber is stiff at first yet molds to your wrist after a couple of days, and the vented ribs keep things from getting clammy during a run.

I've worn it swimming, in the ocean, and under a hot shower and the stainless steel buckle hasn't so much as tarnished. The fluoroelastomer rubber feels dense and premium, way better than the silicone straps I used to buy.

The ribbed design is perfect—it lets my skin breathe during long runs and the fluoroelastomer rubber feels way sturdier than my old silicone strap. Fully submerged it in the ocean and the stainless steel hardware came out spotless, zero water trapped underneath. Exactly what I needed for the Ultra.
