It's not kydex - because after 29 years of concealed carry in a wide variety of holsters, I really hate the stuff, but I recommend the Wild BillS Concealment Covert Carry for all day use. It's very comfortable, very secure, and well made.
You can cant it forward a fair bit - the major limitation is related to getting the front sight caught under your belt, but it's a non issue if you have a Model 60, 36, etc with a gutter sight rather than adjustable sights.
I've used the same holster cut for a 2.125" barrel as well and on the shorter fixed sight Model 36s and 60s canting it is not a problem.
Unlike the poster above, I have not found this holster to ever be uncomfortable whether sitting, standing, walking, driving, etc. even with the 3" barrel.
Leather is old tech but it works and works well.

If you're kayaking I would still go with a leather holster, provided you have the belt to support it. If not, then I'd use a fanny pack like the one sold by 5.11.
