The Hot Tub cover is crafted from 600D heavy-duty Oxford fabric, complete with a waterproof coating. Double-stitched for enhanced durability and tear resistance, it features waterproof adhesive strips on the seams to prevent water infiltration. This cover shields from UV rays, water, and stops water accumulation, maintaining its waterproof effectiveness over time. It keeps your hot tub dry after extended use and can withstand heavy rainfall and snow.
