On my first BW trip over 20 years ago, I had decided I needed a cover to help lower my wind resistance on my Sawyer Autumn Mist. I cut up an old nylon tent, enlisted a girlfriend who could sew, and bought some snaps from the local marina. It went together very well and after testing it on a nearby lake on a gusty day, both on and off I felt there was a significant difference. I have used this cover ever since when wilderness solo tripping, but that is reduced since I married the seamstress girlfriend and she prefers to go with me.
