UIRWAY 18 ft Round 500D Winter Pool Cover with UV Protection and Secure Straps

UIRWAY 500D Winter Pool Cover is a flat, round cover for seasonal, temporary above-ground pools, made in an 18 ft (5.5 m) size for pools with a smooth, accessible rim.

• 500D fabric tested to a tear strength of 780 N — provides a clearly specified measure of fabric strength.
• Gel-coated anti-slip straps, dual bottom drawstrings and adjustable side straps — secure the cover without additional weights.
• UPF 50+ protection blocks 99.9% of harmful UV rays — helps protect pool water and the pool from sun exposure.
• Reduces water evaporation by 90% and chlorine evaporation by 70%–90% — helps maintain water levels and clear water.
• 18 in (46 cm) increased height — helps keep out dust and leaves while limiting sun exposure.
• Reflective strips and side handles — support nighttime visibility, storage and drying.

Keeping a temporary above-ground pool covered can help limit exposure to sun, leaves and dust between uses. This sheet-style cover is made for seasonal use on pools with an accessible, smooth rim, including snap-set and inflatable-ring pools. Its design rests across the water and rim rather than enclosing the pool around built-in equipment, so the intended pool shape and surrounding space matter when choosing it.

Which pools does the UIRWAY 500D Winter Pool Cover fit?

It fits 18 ft round temporary above-ground pools with a smooth, accessory-free rim that the cover can rest across. The flat cover is designed for snap-set or inflatable-ring pools where the rim remains accessible. It is not made to seal around permanent fixtures such as a skimmer, and a surrounding deck can prevent the rim from being accessible for a flush fit. Compare the pool’s shape and size, and make sure the cover can lie evenly over the rim.

• Sheet-style design rests on the pool water and rim.
• Made for temporary, seasonal above-ground pool setups.

How is the cover secured in windy weather?

Its three-part wind-resistant design combines gel-coated anti-slip straps, two drawstrings at the bottom and adjustable straps on both sides. The straps are softer than common steel-wire designs, helping reduce wear and tear on the cover. Reinforced double stitching and waterproof adhesive strips strengthen the seams, while the securing system is designed to hold without extra weights. The fabric has a tested tear strength of 780 N, and the cover is designed to withstand hurricane-force winds.

• Gel-coated straps help resist slipping.
• Bottom drawstrings and side straps allow a close, adjustable fit.

How does the UIRWAY cover help protect pool water?

UPF 50+ fabric blocks 99.9% of harmful UV rays, helping prevent pool discoloration. The cover also reduces water evaporation by 90% and slows chlorine evaporation by 70%–90%. By helping retain water and chlorine, it is designed to reduce water waste and support clear pool water. These are the cover’s stated performance figures; actual conditions can affect results.

• Helps limit water loss while the pool is covered.
• Helps slow chlorine loss and reduce sun exposure.

What details make the cover easier to handle?

The cover has side handles for storage and drying, plus reflective strips to improve visibility around the pool at night. Its increased height helps shield the pool from dust and leaves as well as sun exposure. Limiting exposure to sunlight can help prevent pool materials from becoming brittle and help extend the pool’s lifespan. The fabric is presented as a newly upgraded sustainable material, with no additional material composition specified.

• Reflective detailing is designed to reduce nighttime collision and drowning risks.
• Side handles provide grip points when storing or drying the cover.

The UIRWAY 500D Winter Pool Cover suits owners of temporary, round above-ground pools who want a seasonal sheet cover with defined UV, evaporation and wind-securing features. It is intended for a smooth, accessible rim, rather than a pool with a deck around it or permanent fixtures that need to be enclosed. Its 18 ft round format, layered strap system and reinforced construction make it a fit for that specific pool setup.
