This is the one I've used for a few years now. 40 Ounce Double Wall Vacuum Insulated Stainless Steel Ranger Pro Water Bottle (Black) https://www.amazon.com/dp/B07SB1MJ4Z/ref=cm_sw_r_cp_apa_i_uxIiDbQPR6GSV

I bought it from Walmart (I think it was no more than $15) just becuase I needed a new water bottle so I definitely wasnt expecting the ice that I added in the morning to still be there by the end of my shift.
