Nylon skirts are a nice inexpensive way to keep your legs protected from the sun and paddle drips. They also keep you dry on rainy or wavey days. Delta's skirts feature a nylon cloth coated with polyurethane for water resistance, a strong bungee rim gripping system to firmly secure the skirt to cockpit coaming, a front webbing grab loop, a tensioned deck stay so water runs off rather than collecting and pooling on top of the skirt. They're double-stitched construction with sealed seams to ensure long-lasting wear and water resistance.
The 10AR fits the Delta 10 and (unsurprisingly) the Delta 10AR.
