The sneak is a good design for a sheltered water spray skirt to protect from paddle drip or rain. Due to the nylon construction it will take on a little water around the seal to the cockpit combing if the deck is submerged by waves or the boat is rolled. This can be a safety issue in open water if conditions get rough. A small amount of water drips in every time the combing is submerged. Over time this can put enough water in the cockpit to impact stability.
As a sheltered water spray skirt, the sneak is a great design. It is easily adjusted to the torso and the suspenders hold the tunnel high on the torso. It is comfortable.
I especially like the zipper on the tunnel for ease of getting into the spray skirt or taking the skirt off around bulky paddling clothing.
Another nice feature are the two zippered pockets on the skirt. These have about twice the capacity as the single pocket on the Coastal Tour skirt.
I rate this skirt high for use in sheltered water and the only reason I give it an 8 is because of its limitations in open water. If paddling conditions where the combing will be submerged frequently, consider a neoprene spray skirt.
It was not any harder to get the skirt on; the main difficulty in putting on a nylon skirt is always having to walk the bunched up nylon around the bungee and coaming. Maybe Seals expects users to tighten up the bungees. I should have been more rigorous with the fit, in any case. Of course, some water did pass the skirt, but, it's ok for minimal or unexpected rolling.
I like the main features of the Sneak: elastic suspenders, Velcro waist adjustment, outer zip pockets, and, most of all, the zipper that allows access to items under the skirt. The under-skirt-access zipper also allows the skirt to be donned easily -- hanging loose on the shoulders, by the suspenders -- then snapped, then zipped. The Velcro waist adjusters can be set once, then forgotten.
I was surprised today, to notice that, after such infrequent use, the backside coating on the nylon is crumbling away in several places. On one hand, I don't really expect a nylon skirt to be waterproof, anyway. But, would hope the coating would be more robust.
