Introducing our Updated Tropical-Style 2.0 Quick Release Collection. Our new and improved Tropical-Style Strap is more flexible and comfortable than before. We've still applied a basketweave pattern and diamond-shaped perforations to the design features of our #1-selling Elite Silicone Quick Release watch bands, resulting in our unique version of the iconic Tropical-Style watch bands of the 1960s. With the sturdiness of premium TPU, strategically-placed perforations for micro-adjustments, our famous locking keeper mechanism, and two strap lengths to choose from, this retro-inspired watch band is solid and ready for anything. Waterproof, Dust-proof, Quick Release. Swap out in just a few seconds and without tools! Pair this TPU rubber watch band with our Leather or Canvas quick release bands to take full advantage of the opportunity to 'Switch it Up' on the go.

NOTE: TPU is a much thicker and sturdier material than silicone or rubber. While it will soften slightly over time, please be aware that this strap is designed to endure the harshest of elements and has a firm fit.
