Engineered for Any Condition.
From Arizona sun to Colorado hail — every DaShield cover is pressure-tested before it ships.
Why this vehicle needs the right cover
DaShield car covers for compact, midsize, and full-size cars use a breathable woven laminate construction that manages moisture in both directions: liquid rain blocked from entering the cover from outside, water vapor permitted to exit outward from inside.
The two-directional design addresses the condensation mechanism that non-breathable covers produce. Moisture in the enclosed air under the cover condenses against paint when temperatures drop at night. In high-humidity environments — Florida at 80 to 90 percent summer relative humidity, the Pacific Northwest at 150-plus annual precipitation days — this cycle runs consistently through the wet season.
The woven laminate maintains a hydrostatic barrier against liquid water (ISO 811) while allowing vapor molecules to diffuse through the fiber matrix at ambient conditions. Rain stays out. Humidity exits.
Compact, midsize, and full-size cars are mapped as separate sizing categories at vehicle selection. Roof height, windshield rake, and trunk profile differ across passenger car size classes, and a cover patterned for the correct size class seals properly at the mirror caps, rocker panels, and deck lid — which is where loose covers allow cover-and-paint contact abrasion in coastal wind conditions.
Select your make and model at the vehicle selector to receive the cover sized for your specific car and designed for the moisture environment of coastal, tropical, and high-precipitation climates.
Nash 660 cover priorities
Engineered for the Nash 660
For a compact, midsize, or full-size car parked outdoors in a humid or rainy climate, three engineering priorities define the correct cover selection.
First, two-directional moisture management. The breathable woven laminate blocks liquid water from entering while allowing water vapor to exit outward. This is the property that prevents the condensation cycle — moisture in the enclosed air depositing on cooler paint surfaces at night — from accumulating under the cover. Non-woven polypropylene and sealed PVC covers have low vapor transmission rates. They block rain and trap condensation equally. The woven construction resolves both directions as a single fabric design rather than a compromise between them.
Second, all-climate performance without humidity degradation. The Ultimum and Vanguard UHD are designed for continuous use in high-humidity, high-precipitation environments. Florida's five-month wet season, the Pacific Northwest's 150-plus annual precipitation days, and salt-air coastal exposure do not degrade the woven laminate's vapor transmission function. The cover maintains its breathable waterproof performance without a humidity ceiling.
Third, size-class fit for compact, midsize, and full-size cars. DaShield maps compact, midsize, and full-size passenger cars as separate sizing categories — windshield rake angle, roofline height, and trunk profile differ across the IIHS size classification range. The correct size class produces a cover that seats properly at the mirror and rocker anchor points without billowing in coastal wind conditions or pulling tight at the windshield.
Ultimum covers compact and midsize cars at $209.99, full-size at $219.99, with a Lifetime warranty. Vanguard UHD covers the same vehicle categories at $179.99 and $199.99 with a 5-Year warranty. Both use identical breathable woven laminate construction. Care for all woven outdoor covers: wipe-down with damp cloth only — machine washing degrades the laminate barrier and voids the warranty.
