This cooler isn't messing around. It features walls that are nearly three inches thick, featuring commercial-grade polyurethane and a silicone sealing ring on the lid to lock in cold and keep it there. In fact, the cooler can keep your drinks cold for up to four days!

A special diversion groove at the bottom separates ice and water to slow the melting process. There's also a plug at the bottom so you can let out water as you go — and you don't need to tilt the cooler to offload water.

The lid is a little different than most coolers: Instead of using a hinge, it comes entirely off, allowing you 360-degree access to what's inside. (Worth noting: The lid and cooler is so sturdy that it can double as a seat or table.)

The capacity is generous: This cooler can hold up to 30 cans and 400 pounds. Ergonomic handles on two sides allow for easy carrying.

Fans swear the East Oak cooler performs similarly to a Yeti — and at a fraction of the cost. "This is a fantastic cooler! The quality is easily on par with Yeti coolers," said a five-star fan. "It is thoughtfully designed. First off, it's lightweight. I can easily lift it, and the round shape makes it easy to maneuver it. And the rope handles are very convenient to haul it around ... they allow you to stand upright when carrying it, instead of a weird hunched position because ya need to reach around the edges like with other coolers."

A fellow happy customer says the cooler can hold ice for even longer than four days. "The ice retention is seven to 10 days if you keep the cooler out of the sun and had it pre chilled for 24 hours before using it," they shared. "The average ice retention under normal circumstances is five to six days."

"Look out Yeti!" said a satisfied shopper. "It travels well and keeps things cold — longer than my several Coleman coolers. ... It's cool you can open it from both sides! I like how you can drain it easily, too."
