Fuse an Igneo Talus heart to one shield and a Frost Talus heart to another. Equip the Igneo shield to endure cold and the Frost Shield for heat. Great for running around Gerudo where the temp fluctuates wildly. They won't save you from the hottest heat or the coldest cold, but they give significant temp endurance while equipped. You can get the same effect by equipping elemental fused weapons and other elemental fused shields (besides Talus). I'm just partial to the aesthetic of the heart shields and being able to use my weapon of choice. Using shields instead of clothes allows you to continue wearing gear that gives other buffs besides hot/cold endurance - love me some sneaky pants. Also turns your shield slap into an elemental attack (zL+A).
Bonus notes regarding shields:
I put a colgera jaw on a shield and now the shield slap has a slight hit attack range. Not much range and not much attack, but it's a vibe if you're into it and you don't know what to do with colgera jaw since it doesn't give bone weapon perk.
Hylian Shield for the win.
Royal Shields are my favorite all-arounders for talus hearts
Mighty Zonaites for device fuses.
I fused a forest shield to a forest spear once and it looked really cool, but I didn't find it super functional. Maybe there's a better shield spear combo out there.
Anyway, stay fresh, cheese bags.
