Anti-mildew treated interior face
Rated for sustained heavy rainfall exposure

Waterproof vs Water-Resistant

Water-resistant 600D with PU coating beads light rain. Rain-proof packages add PVC or TPU lamination and seam sealing so standing water on a flat rooftop does not wick through stitching lines.

  • Water-resistant: off-season dust and light shower duty
  • Rain-proof: monsoon, coastal, and flat-roof pooling
  • See waterproof cooler covers category for SKU detail
  • Always drain the cooler before sealing under any cover

Construction Details

Critical points are the top panel seam, corner gussets, and hem where water can channel inward. We position low-point grommets on large horizontal tops and reinforce around zippered access panels.

  • PVC-backed 300D or TPU-laminated 600D shell options
  • Double-stitched then sealed seam on premium tier
  • Split corners available for side electrical boxes
  • Compatible with ratchet tie-down without piercing sealed zones

Climate & Installation Notes

Rain-proof covers are stiffer than oxford polyester. Allow the fabric to seat 48 hours after install and re-tension straps. In humid climates, dry the unit fully before cover-up to prevent mildew under the laminate.

  • Not a substitute for draining the reservoir
  • Pair with vented hem if condensation is observed
  • Inspect grommets annually for debris blockage
  • Rooftop installs: slope top toward drainage grommets
