Review on 🧲 Iron °Flask Carabiner Straw Lid: Ultimate Accessory for Wide Mouth Insulated Sports Water Bottles - BPA Free, Includes 2 Lids, 4 Straws, and 2 Cleaning Brushes by Brandon Plowden

These are my favorite straw caps. Love how easy it is to get water in, some other straw lids have a hard time getting the right amount of water in no matter how hard you vacuum, but not with these lids. These lids also don't make that annoying whistling noise when drinking. I have actually replaced the caps on all mine and my family's other wide mouth bottles with iron bottle caps. These caps are compatible not only with wide mouth iron flasks, but also with wide neck versions of the following vacuum flask brands. Hydroflask, Mira, Simple Modern, Thermoflask and BalanceForm.
