Ice Shards:Mining (normal) ice would get you ice shards by using fortune.

Frost Resistance Potions:Using ice shards in a brewing stand and mixing it with awkward potions would give you a light blue version of fire resistance potions that can help you get through powder snow and ice caves without freezing,it’s time can also be extended.

Ice Cave Frost:Walking through ice caves will get you freezing after a minute of being in the biome and will slowly get you colder the more higher you get into the cave and the longer you are in the cave.
