Warm But Not Bulky Bibs?

Looking for some warm bibs that aren’t bulky for ice fishing.

Currently I have Striker Trekker bibs, they’re bulky as hell and honestly not all that warm.

I’d like something more comfortable like my Arctic Shield hunting bibs. They’re as warm or warmer, sleeker fitting, more flexible, more windproof etc. my Striker bibs feel like wearing cardboard in comparison. I see they make some “ice” stuff, but wondering what else is out there that could be similar??

The new striker apex is bad ass. Way less bult then my climate suit and very warm. Other then that brands like klim and snowmobile gear is way warm and not bulky. But they aren’t float suits.
