Prior to reading about the positive experiences a few here have had with nothing more than a regular coil zipper on a shelter door (no flap), I would have used a waterproof zipper.
I don't care for the drag of the waterproof zippers though. Besides the hassle of it, seems the extra difficulty would add extra stress on the my .51 oz cuben seams. I see that a couple people have recommended zipper lubricant to make things easier. That works on my drysuit but by the nature of the zipper, there's still a lot of drag. I assume a small waterproof zipper would have similar results (easier but still draggy).
I'm having my Hexamid converted to a Wild Oasis like shelter. I need to decide by the end of the day what zipper I should use. I like the simplicity of no zipper flap. I'm in S Idaho. Some rain but it's not like the Pacific NW.
I'm leaning towards a regular coil zipper. Anyone think this is a mistake?
