Thoughtfully engineered
Three practical reasons to rethink your next hot tub cover.
AirLoc™ panels have no foam core to soak up water, so the cover weighs the same out of the box and years later: 35–40 lb, depending on size.
Learn about water resistanceThe sealed AirLoc™ air core has nothing in it to absorb water, so its insulation stays consistent for the life of the cover.
See how AIRCAP insulatesThree ZipTech™ skirt depths come in the box, and a worn or damaged skirt can be replaced on its own, without replacing the whole cover.

The Saratoga Spa Company has built hot tubs in Latham, New York since 1984, and its lines — Luxury, Special Edition, Limited Edition, Cottage and Geyser — are mostly rectangles. The exception is one 84" × 84" footprint, which Saratoga uses for four current models: the Canfield (Luxury), the C35 and C40 (Special Edition) and the Olympia Limited (Limited Edition). The Canfield and C40 have a lounge and the C35 and Olympia Limited do not, but all four measure 84" × 84" across the cabinet and take the AIRCAP 1™ Small (fits 83"–85").
Five retired Saratogas share the same 84" × 84" footprint in Saratoga’s own owner’s manuals and take the Small as well. From the Adirondack line come the Cascade and the Marcy, which Saratoga’s Adirondack & Champion manuals also list as the Conquest 280. Saratoga’s plan drawings of the Marcy and the Canfield match seat for seat, so the Marcy shares the Canfield’s photo here. From the mid-2000s Luxury and Select Plus lines come the Excelsior, the Clifton Plus and the Grand, each drawn as a square in Saratoga’s manuals. We list those three without a photo, because the only top views of them we have found are those drawings.
Older names to measure first. Our Excelsior (2004–2005) row is for the 84" square Excelsior in Saratoga’s 2004 and 2005 manuals. Saratoga used the Excelsior name before 2004 too, but its earlier manuals give that tub a different water volume and no size, so measure an earlier Excelsior before ordering. An Olympia from Saratoga’s 2000–2003 Luxury line predates today’s Olympia Limited, and Saratoga’s manuals print no size for it, so measure one before ordering too.
Everything else Saratoga makes is a rectangle — the Putnam (75" × 84"), Beekman, Empire and G50 (89" × 93"), Lincoln and L50 (90" × 94"), Broadway (92" × 108"), R45 and Regent (84" × 90"), Collins, Whitman, Talbot and Palmer (80" × 84"), and the smaller Polo, Adelphi, B15, A24 and Glenwood — or round: the Geyser Paradise and Glacier are 78½" and 92" in diameter. Among retired models, the Georgian (Challenger 310), Victoria, Pavilion and Franklin Plus (89" × 93"), the Caroga (Vision 220), Saranac (Spectra 250), C28, Columbian and Lexington Plus (80" × 84") and the P13 (59" × 82") are rectangles too, and the P25 is a 78½" round. No square cover fits any of those.
Measure your spa side to side across the top of the cabinet before ordering; the SureFit™ measuring guide walks through it in two measurements. If your measurement falls between two sizes, round up.
