The Boating Tumblers and Sleeves
Sea Cups stay in place
With our unique proprietary design, the Sea Cups silicone slip-on ensures our tumbler -or your tumbler- fits snugly in most any style of cup holder from land to sea. The compressible bumps make it happen. Plus the high quality silicone composition guarantees a sure grip when conditions get sloppy.
