I got the discovery heat float bibs. Haven’t used them on the ice yet but seem pretty nice and very warm. They have a lot more insulation and thicker than my striker predator bibs so I’ll pick and choose when I wear them probably. Maybe they compare more to the hardwater or climate bibs as far a thickness? They don’t have a full length leg zipper up to the hip, but I can look past that. The heat is powered off your typical portable usb battery pack for recharging phones and other stuff on the go. They have a sizing chart on their website, but I got a medium bib, and also wear a medium predator bib. I will note they are more fitted then my predators(slightly baggy in the legs), part of this may be because of the extra insulation.
Being a European company making clothes to wear ice fishing over there in the harsh conditions and that the USA ice fishing team has been wearing Norfin gear for quite awhile I feel pretty confident it will hold up.
