Replacements for neoprene hatch covers on older model Mirage 530 & 580. 

Made from Superstretch Aquatherm. A lightweight, waterproof, durable, material - the hatch covers feature a static drawstring with pull cord to lock cover in place. 

 Aquatherm deck fabric has 360 degree stretch, instant memory return, and has 80% less volume and weight compared with traditional neoprene products without compromising performance. It is comfortable, durable and supple, UV stable, waterproof and fast drying. 

Soft hatch covers should have a hard cover over the top to prevent implosion if hit by a wave.
Unlike the other Aquatherm hatch covers, these do not have a toggle, instead  single bungee cord inside sleeve (same as the cockpit covers) with a tape pull tab.

Fits hatch rim 19.5" x 12" (50 x 31cm)
