Lets talk basics. This skirt is all about basic. The rand is a 6.25 half round rubber rand, the deck and tunnel are constructed of 3.5mm Neoprene, which will give you the most secure, dry fit available for comfort and durability. The Basic Rand is only available in preferred fit and not the tight fit.  Available in 10" or 14" tunnel height and ladies fit.

Ladies fit tunnel has a 2 inch flair at the hip area allowing for a better fit for the slimmer waist. Most women have wider hips than men, but smaller waist lines.

Needed for a custom fit is your setback.  This is the distance from the outside edge of your cockpit rim to the small of your back sitting up as straight as possible.
