The Seals site recommended the 2.2 size for my Liquidlogic XP10, so I bought that. I found it impossible to seat without assistance, so I put it on (without me) and left it on for a few days to "adapt." That didn't help, nor did subsequent usage. I've used skirts frequently for 10 years, so am not unfamiliar with the usage. Subsequent to this, I noticed a number of outfitters recommend the larger size for this boat which, I assume is based on their experience and feedback from customer.
Aside from the fit (not insignificant), the construction and materials appear adequate.I own two Seals spray skirts, a Tropical Tour and an Extreme Tour.
The Extreme Tour gets the most use. The neoprene deck fits my Romany cockpit well and the skirt does a good job of keeping water out. However if my torso is getting into the water I get water leaking down between the tunnel and my torso. Also, the nylon used in the tunnel is a little noisy as it moves back and forth with torso rotation - slightly annoying on a very quite day.
The Tropical Tour is my back up skirt. It doesn't fit the cockpit rim as well and edging the rim under water will cause water to leak into the boat. It is certainly not as dry as the the Extreme Tour.
Seals Customer service is 1st-rate! I broke the implosion bar on the Tropical Tour and Seals fixed it quickly at no charge."Mariner" model.
Non-neoprene breathable material with codura reinforcement around the cockpit rim area on top & a rubberized coating on the inside of the rim. This skirt features an implosion bar, large mesh pocket on top, adjustable bungees over the pocket, reflective stripe, and at least 10 attachment loops to clip things like VHF's, or a GPS to.
The forward tip of the inside of the skirt is reinforced with nylon webbing that is part of the grab loop. The grab loop itself has a large rubber handle on it, and is tethered to the bungees, which hold the handle in the same position at all times - a feature I really like, because it makes it all but impossible to attach the skirt to the coaming with the grab loop inside the boat. It also assures you that the handle will always be in the same place no matter what your situation.
There is a paddle park clip near the tunnel on the deck. A bit over the top, IMO, but useful on a windy day if you don't have sufficient deck rigging to park your paddle otherwise. It also takes a bit of learning to use efficiently, but it is secure when closed around a paddle shaft. The tunnel itself is tapered & allows excellent range of motion for rolling and for differing seat positions in various boats. The tunnel also has a rubberized rim and velcro waist adjustment. Heavier paddlers may find it a bit snug, as it took very little adjustment to conform to my 34" waist. Suspenders are included with the skirt, but I found no need for them.
With the skirt mated to a drytop, I found no appreciable leakage after about 10 rolls.
A bit pricey compared to neoprene, but worth it. The utility of the pocket and attachment loops is obvious --- you can keep your radio and emergency gear on your sprayskirt in case of a wet exit, even if you don't have a lot of storage in your PFD. Overall, I like the skirt a lot.
