Curious what out of the box solutions folks have used for cold water canyons. We are hitting Kolob in a week and I was planning to wear my 4/3 Full wetsuit with a 3/2 farmer john over the top of it (did this combo in Imlay one year and it worked really well). I will also be wearing a neoprene cap, neo socks and neo gloves. I've taken a dry top as a back up in case I got cold to put over a wetsuit but haven't ever really needed to pull it out. Not sure how well it will work once my wetsuit is wet. So...what combinations have worked well for you or not so well.
