MIYCOO MI Bac-1 Cooler Backpack, 28L, Two Compartments, 40-Can Capacity

Made from polyester, the MIYCOO MI Bac-1 is a soft cooler backpack measuring 8.6" D x 11" W x 15.7" H. Its 28-liter capacity and two-compartment layout give drinks, snacks, and everyday picnic items dedicated space in one portable bag.

The backpack format makes it easier to carry refreshments on the move, while the insulated design is suited to beach days, road trips, and outdoor meals.

The essentials

The main compartments separate chilled items from snacks and utensils. The lower compartment is designed for drinks and fruit, while the top pocket offers a convenient place for dry food and small picnic essentials. The bag can hold up to 40 cans (330 ml), giving you room to pack for a group outing without relying on a hand-carried cooler.

A seamless, hot-pressed liner is designed to help prevent leaks. Two adjustable side straps secure bottles, and the manufacturer notes they can hold two wine bottles on each side. A bottle opener on the shoulder strap keeps one handy for picnic breaks, while an extendable zip pocket provides access to valuables such as a cell phone or tissues. Padded, ergonomic shoulder straps are designed to ease pressure while carrying the pack.

Buyer feedback often highlights the roomy storage and temperature retention on trips. Reports about leakage and durability are mixed: some buyers say the bag does not leak, while others describe water escaping through the zipper or the bag tearing after a short period of use.

Who it’s for

This cooler backpack is suited to people who want to carry food and drinks hands-free for a picnic, beach visit, lunch, or day outdoors. Its divided storage is especially useful when you want chilled drinks in one area and snacks or utensils in another. If your plans involve walking from a parked car to a beach spot or picnic table, the backpack design offers a practical alternative to carrying a cooler by hand.

Best use cases

Pack cans, fruit, and picnic snacks for a beach day, barbecue, camping trip, or hike. The separate upper and lower compartments help organize the load, and the zip pocket keeps small valuables within reach. For a road trip, the two-section design makes it easier to keep refreshments together while separating dry snacks from drinks. The side straps add a dedicated place for bottles, and the shoulder-strap opener is a useful detail for outdoor gatherings. It suits you if you want a portable cooler with room for refreshments and a simple way to carry them on your back.
