Swimline Hydrotools Supreme Guard Winter Pool Cover for 28 ft Round Pools — 31 ft Green/Black, Heavy-Duty UV & Chemical Resistant

Swimline’s Hydrotools Supreme Guard is a heavy-duty, 31-foot winter cover engineered to shield 28-foot round above-ground pools from snow, leaves, and freeze-season debris.

Designed for pool owners who want a long-lasting, easy-to-install winterization solution, this Hydrotools cover combines a tightly woven 12 x 12 scrim fabric with UV and chemical resistance. The extra 3-foot overlap gives room for secure anchoring and accessories such as air pillows, while the included steel cable and winch help fasten the cover firmly around the pool perimeter. Built to sit loosely on the water surface, the cover keeps solid waste out without allowing water to pass through, simplifying spring cleanup.

How does this cover protect my pool during winter?

The Supreme Guard material is a dense woven fabric that blocks leaves, ice chunks, and large debris from entering your pool. It’s designed to resist UV degradation and the effects of pool chemicals so it keeps performing season after season.

• 12 x 12 scrim weave prevents solids from penetrating
• UV and chemical-treated fabric for longer outdoor life
• Sits loosely on water to shed debris without pooling

Will it fit my 28-foot round above-ground pool?

This model measures 31 feet overall, providing overlap for secure attachment to a 28-foot pool. The extra material ensures you can use air pillows or other winter accessories and still get a snug, stress-free fit.

• 31 ft cover size recommended for 28 ft round pools
• Extra overlap accommodates rail variations and accessories
• Advice: go one size up for large top rails or raised decks

How simple is installation and what’s included?

Installation is straightforward: spread the cover over the pool, thread the supplied steel cable through the perimeter grommets, and tighten with the included winch. The kit arrives ready to use so you won’t need to source additional fastening parts.

• Perimeter grommets for fast, even securing
• Steel cable and manual winch included for anchoring
• Lightweight design eases positioning and removal

How should I size and maintain the cover for best results?

The cover should rest loosely on the water surface rather than being pulled taut across the pool. Proper tension prevents overstress on the grommets and material, and simple winter care will extend service life.

• Let the cover float slightly—do not overtighten
• Clear heavy snow accumulation to avoid excessive load
• Store folded and dry in a cool, ventilated place when not in use

Who is this for: The Swimline Hydrotools Supreme Guard 31 ft cover is ideal for above-ground pool owners with a 28-foot round pool who want a durable, low-maintenance winter solution. It suits homeowners who prefer an included fastening kit (cable and winch) and need a cover that resists UV, chemicals, and typical winter debris. If you value easy seasonal installation and reduced spring cleanup, this heavy-duty cover is a practical choice.
