I've own a Contrail and I must say that it is an ok shelter, but there are many features which annoyed me.
Primarily, Silnylon. I loathe this fabric for a shelter. Sags when wet, slippery as hell, and hard to repair in field. Sure it is cheap, sure it is kind of lightweight, but after enough time with the Contrail I had enough. Silnylon/The Contrail is ok if you are on a budget, but eventually, you will move to some cuben shelter. I suggest doing it sooner than later.
I do not know if Henry changed it but the velcro shut door was the bain of my existence and cause many horrible nights of sleep due to the fact when you pitch a Contrail for extreme storm conditions, everything is very taut/tight. If a strong gust of wind comes through or in the middle of the night nature calls, reconnecting the door when getting back in or after the gust becomes a battle of rain getting and not being able to velcro well enough. A lightweight zipper would add a little weight but go a long way to helping.
You need to do some after market mods to make it storm proof. Sure, we all do after market mods, but this has been known by the designers of the Contrail and yet never fully addressed. Instead of selling the Contrail with a foot storm rod and including it in the directions, we must figure it out on here or else where. Again, I would not complain about it except for the fact it is a well known issue.
