Review on 🍾 BellFlask 15 oz Non-Metal Plastic Reusable Flask - Concealable Liquor Hydration for Travel, Vacation, Sports, Concerts, Events - Pack of 3 Flasks (Black) + Free Filling Funnel - Patented Design by Darryl Pendall

Absolutely NOT for hiking. I filled two with 12oz whiskey and they kept leaking throughout my trip. They leak where the plastic wraps around the spout under pressure. Don't buy them if you pack them tightly. Update: The company contacted me and sent me a fresh batch to test. In short, they did not live up to my standards. I left it on overnight with constant pressure. Leaked by morning. Excellent service/customer support. But my original statement stands. They are absolutely not intended for hiking. They flow at constant pressure.
