You can use BunkSox as either a mattress cover or bottom sheet. And because the soft, durable fabric (50% cotton 50% polyester) is specially manufactured to stretch, the BunkSox conforms to just about any mattress, including a coil mattress or a V berth. Use it as V berth bedding, boat bedding or sailboat bedding.
When your BunkSox mattress cover/boat sheet gets dirty, just toss it in the washing machine. Launder it the way you'd launder marine bedding, sheets or blankets — no worries. It's manufactured to last, but you can double the life of a BunkSox sheet by alternating which side you sleep on.
The BunkSox comes in three convenient widths: Small (24 to 30 inches), Medium (30 to 40 inches) and Large (40 to 50 inches). To select the size that's right for you, simply measure the width of your mattress. Because the fabric is "super-stretchy" any one of the sizes will accomodate a standard mattress depth.
