I have a Jackson 4 Fun kayak and had to order an XL Seals spray skirt to fit my cockpit. I ordered a pink sprayskirt that has a lower tunnel and is made to fit female bodies. It took some work getting it on the first time, but it works wonderful. I will be using it on an Ottawa River kayaking instruction course for 3 days in Sept 2013. Brenna Kelly is giving us an awesome 3 day, 4 night kayaking instruction course for women. Super stoked.
