Check out our selection of add-on, activity specific, seat pocket packs. The modular system allows you to snap in any of the add-on pockets to the rear sit of some Standard Sit-On-Top Seats, or go without. This gives you options for sport specific packs to pick and choose from. Fish on Saturdays, Tour on Sundays! Please note: Seat pack and seat must be matching brands! Select Surf to Summit (STS) brand seat packs for STS seats. Select Watersport Warehouse (WSW) brand seat packs for WSW seats.
