The MadElk universe now has a lake swim mat. Its big 18ft x 6ft. It's so much fun. We paddle out to the middle of the lake and the kids have a blast jumping off it and playing keep away from MadDadElk (their dad). We even rollup the pad and let them climb up and jump off it, or play log roll and see who can balance the longest.
Check out our video with some swim mat action.
