Use the Epic seat pads for comfort or stack them to speed the transition to a narrower boat. The Epic Seat Pad Set uses hook and loop fasteners so you can use 1 pad for everyday comfort, then add another 1, 2, or 3 pads to raise your center of gravity and help simulate a less stable boat. You can also use them on flat water and then remove them when you get into rougher conditions. Set includes 4 pads.
