Hydro Flask is the expert in insulation. We were the first to bring an all insulated bottle line to market and we continue to focus 100% on double-walled, vacuum insulated products.
TempShield Insulation is our unique way of applying vacuum insulation - from the proprietary ovens we use to our unique sealing process – all of which ensure temperatures remain cold up to 24 hours and hot up to 6 hours, providing our customers with refreshment they can count on, each and every time.
