Wide Mouth Flex Cap

The last time you saw your water bottle's original cap, it was falling down a desert tower. Instead of searching the sands, replace it with Hydro Flask's Wide Mouth Flex Cap. Its stainless steel construction includes Honeycomb insulation to help you drinks stay cold or hot longer. The flexible loop is durable and convenient for hikes and bikes to summer concerts.
