Bunksox, Hypervent & DexDamp

Mac's is a national distributor for Bunksox, Hypervent, DexDamp and carbon fiber seat heaters. It's smart to purchase some of these products together. For example, Hypervent will help keep your Bunksox dry. If you're buying car seat covers, save money by installing a seat heater at the same time.

The BunkSox® mattress cover is a bottom sheet for mattresses. They're better than standard boat sheets because they never come untucked. They fit almost any bunk, including a V-berth. BunkSox are the perfect choice for boat bedding, marine bedding or sailboat bedding. Keep your BunkSox dry with HyperVent.



Onboard condensation is more than a nuisance. Unwanted moisture not only damages furniture, gear and equipment, it spawns unhealthy mold and mildew. Reduce marine condensation with HyperVent. Keep your BunkSox dry by placing a sheet of HyperVent underneath the mattress.



DexDamp is a flexible, peel and stick sheet designed to reduce vibration and noise. It can be applied directly to metal or PVC conduits and automotive floor boards, headliners, trunks, door panels or engine fire walls. DexDamp's damping material is covered with a thin aluminum foil layer which improves performance and provides a paintable, finished surface.

Our aftermarket carbon fiber seat heaters are also affordable and virtually invisible. If you're soundproofing your car or installing seat covers you can save money by adding a seat heater.
