I like that closure! I'm a guy, I made a skirt with a few pleats, but 60" of fabric didn't permit enough pleats to call it a kilt. Mine is opaque green urethane coated nylon, so I can hide my derriere while I change my shorts while standing–I'll only change inside if it's raining hard. Also, I don't even have to wear anything underneath (TMI?). I sewed mine with a front vertical velcro closure, so I don't have to climb into it from above and if I get fat, I just add more Velcro. My waistband is two way stretch polyester.
Other properties: Quiet. Good for sitting on wet logs. Good windbreaker when the mercury drops.
I had to add a couple of little pockets to the front to slip in tent stakes to weight the bottom after a mild headwind made the skirt ride up.
Works great for both rain and bug protection. In combination with rain "legs" these far outperformed the Gore tex rain pants in which my hiking buddy sweated–I never felt clammy during our 3 hour hike out of the woods in a wet drizzle. The rain legs also matched the protection of Gore tex gaiters without even an instep strap and at only 30% of the Goretex weight.
My skirt weight: 3 oz. The rain legs weigh 2 oz. The set cost maybe $15 from Rockywoods & Joann Fabric with 40% off coupons:
Fabric 2 yd of ure coated nylon
some velcro $1 per 3'
some two way stretch polyester.
My skirt permits decent range of motion. for Version 2.0 I might reduce the fabric from 60" to 40" & add a slit that closes with either Velcro or a hem-to-hip zipper on both sides to preserve/add range of motion.
Happy trails on the JMT!
