Re: 5 Years With An Aerostich
I got 5 years and 30k on mine with 0 complaints. Its dirty and turning a lighter shade of red but all the zippers and seams are still tip top. I'm also one of the lucky 50% or so that doesnt suffer from "Aerostich Crotch." Guess I just fill it out more so there is no room for the water to pool.

All joking aside most wet crotch sufferers that Ive spoken to "fixed" the problem by making sure to tuck the crotch (of the suit, not their junk, I assume) on rainy days to where there is no place for the water to pool and subsequently leak through the zipper. From what Ive heard on the 2 piece roadcrafters wet crotch is a non issue. The price you pay for convenience I guess.
On hot days leaving the sleeves loose and over your gloves gives a great ram air swamp cooling effect. Lifting up your elbows like doing the chicken dance now and then opens the pit vents a little wider and will cool all the way down to your waist.
Ironically I also purchased a Kilimanjaro prior to my stich. The stich is much cooler in the summer due to the stiffer cuffs allowing much more air up the sleeves. The pit vents catch much more air than the totally inadequate chest vents on the First Gear. Well when behind a faring, the chest vents may work well on a naked bike but I wouldnt know. I did crash test the Kilimanjaro albeit off the bike. I was walking across the street after parking my bike and got scooped up by a red light runner and sent sliding across 3 lanes. I got up rather angry but for the most part unscathed, my helmet was a different story since it was in my hand at the time. Other than being sore and bruised the next few days I didnt have a scratch, nor did the jacket.
