I'm shopping for the "best" waterproof, insulated bibs for my husband since I ruined his Nite Lite's last winter

So far I've discovered that many people don't like the Nite Lite's but do like Mule's and Dan's a lot.
Does anybody here have experience with these brands? Or maybe something different that you liked more??
I'm not looking to spend too much more than $100, but he does NEED them for his trapping/snaring and as you all know 'tis the season!
They MUST be waterproof and insulated.
Any help is greatly appreciated!
Thanks guys!
