I went to REI last night to purchase the "REI Lite-Core Sit Pad" for my future Kodiak seat. They were out of stock, but they did have the "Therm-a-Rest Lite Seat", which had slightly better reviews on-line for $5 more. I intend to use two VELCRO strips oriented fore and aft for fastening and adjustment. No extra material surrounding the seat pad to work with. Does anyone know how the VELCRO adhesive strips hold-up over time? Other advice?
