Each of our custom vented storage covers are made from a very high end 600 Denier solution dyed polyester to resist fading and dry rot. We use only the highest quality thread that is designed to withstand the harsh UV rays from the sun without it deteriorating. Each cover is custom fitted to your specific year, make and model watercraft so you know it will have a great look whether sitting on your dock or traveling down the road on your trailer. All covers have a shock cord sewn into the hem and include adjustable tie down straps for added security while trailering locally. Custom storage covers are sewn to order and usually ship in 48-72 hrs. Being a custom product there are no returns accepted. Covers have a 1 year warranty against any defects in material or workmanship.
