The Native Sprayskirts are made from urethane coated 400 denier nylon - fully coated on the underside for waterproofness and 'kiss-coated' on the exterior to keep the fabric from absorbing moisture. Skirts clip or slide into the recessed channel to create a dry, secure seal. The 2010 model fits Ultimate 14.5 kayaks that have the black plastic T-handles. Choose the 2011+ model if your Ultimate 14.5 is a model year 2011-2014 and has the softgrip handles. Skirt does not fit any Ultimate FX series kayaks.
This adds a lot of storage room to the kayak. I use the kayak in the solo configuration mostly, so I can stash a lot of gear up front. It sees to be pretty secure; I have traveled few hundred miles with it attached to the kayak (on top of my truck) with out any problems. The mesh pocket is handy for quickly stowing the paddle.
The skirt was fine, with one exception: the plastic piece which runs crossways to maintain a tight bow in the skirt was poorly made and broke in half quite easily when I put my hand on it while cleaning the kayak after our trip.
Fits like a glove! Easy to install and remove.
Works as designed, and well made. My only gripe is the plastic "stay" that doesn't seem to fit in the slots on the underside of the skirt. There is a velcro slot on the top of the skirt where it fits easily, however.
