The Iron Flask 25 oz Retro Water Bottle is the perfect size for all-day hydration, whether that’s at your desk, around town or around a campfire. Vacuum insulation protects your drink from outside temperatures keeping your drinks cold for 28 hours and hot for 12 hours and the included bottle brush comes in handy for quick and easy cleaning. Plus, thanks to its sleek, classic shape and fresh colorways, it doubles as a conversation starter (finally, Pat from accounting will have something other than your haircut to comment on).
