“The entry price that doesn’t cut corners on protection.”
Economy/value workhorse — for gen pop, intake, high-turnover, and infirmary housing.
- Permanent fluid barrier — 309 psi hydrostatic. Fully fluid-proof and wipe-clean for intake, high- turnover, incontinence, and medical housing.
- Flame-retardant for the life of the fabric; antimicrobial and self-deodorizing — combats bacterial and fungal growth.
- Heavy 14 oz double-coated green vinyl over a 9×9 1000D scrim — tear 70 lb, tensile 200 lb/in, adhesion “cannot separate.”
- Fiber core keeps the price low — the sanitary, budget option in the AirString line.
