GoPong s Tropic Tan Sunscreen Sport Flask was designed to look like a regular bottle of sunscreen so you can fill the bottle with your favorite alcohol and take it to any outdoor event. Any suspicious eyes will quickly look over your bottle of sunscreen and allow you to bring your flask almost anywhere. We do not condone any illegal uses but like you we hate paying 12 for poolside drinks. Each flask holds 8oz and can easily be filled though its extra wide mouth (small funnel included). Its screw cap provides an air-tight seal to prevent any leaking of liquid or odors. Once you are ready to drink simply unscrew the cap and mix with your favorite beverage. This 2 Pack includes an SPF 15 and an SPF 30 so you can sneak 2 kinds of alcohol around. The flask will pay for itself after one use so get yours today! Please remember to always obey all local drinking laws.
