144" x 94" Swim Spa Cover for H2X Trainer 12

Protect your H2X Trainer 12 swim spa with this premium factory OEM replacement cover, precision-built to help retain heat, prevent moisture intrusion, and withstand outdoor elements. Engineered with a dense, tapered foam core and wrapped in durable marine-grade vinyl, this high-performance cover helps maximize your spa’s energy efficiency and longevity.

Key Features of this Swim Spa Cover:

• Energy-Saving Tapered Foam Core: Built with a 6-inch center thickness that tapers to 4 inches at the edges, helping reduce evaporation and heat loss. According to the U.S. Department of Energy, properly fitted covers are one of the most effective ways to retain heat and cut energy use in spas and pools. The 1.5 lb foam density further boosts insulation, making your swim spa more efficient year-round.
• Marine-Grade Vinyl Exterior: Crafted from mildew-resistant, UV-protected marine vinyl for excellent durability against sun, rain, and snow.
• Heat-Sealed Core: A full-length heat seal traps warmth inside your spa while the exterior 12 oz. chemical-resistant vinyl scrim provides added protection.
• Three-Panel Skirt: The triple-section skirt helps seal in warmth while also shielding against dirt, leaves, and debris.
• Upgraded Rubber Grip Handles: Reinforced, non-slip rubber handles make lifting and maneuvering the cover easier than ever.
• Lockable Safety Straps: Four secure locking hardware attachments keep the cover firmly in place—whether you're securing it against weather or for child safety.
• Galvanized Steel Bracing: Heavy-duty steel brackets provide additional internal support and resistance to sagging over time.
• Reinforced Underside: The bottom layer features 11 oz. mildew-treated reinforced vinyl for added durability where it matters most.
• Precision Stitching: Double-stitched seams provide 27 points of reinforcement, helping the cover resist wear and maintain shape under repeated use.
