GLENKEY Double Deck Insulated Lunch Box - Expandable 22L Cooler Bag

In this review the GLENKEY Double Deck Insulated Lunch Box is evaluated as a roomy, practical cooler bag aimed at commuters, shift workers, and small family outings. The single biggest reason to buy is its expandable dual-compartment design that combines a large 22L capacity with a top section that unzips to add 6L, so it can hold enough meals and drinks for two people or a full day of food and beverages. The review finds it particularly useful when strong insulation and organized storage matter.

Key Features

• Expandable capacity: The top compartment expands to add 6L, letting the bag fit up to 36 cans of 350ml soda when fully opened, which is ideal for longer trips or shared meals.
• Dual compartments: Separate top and bottom sections make it simple to keep wet items or cold drinks apart from dry snacks and utensils.
• Thick insulation: A 6mm thick insulation liner helps keep food cold or warm for up to 8 hours, supporting work shifts and day trips without an ice refill.
• Water-resistant and leakproof: Durable outer fabric and a thickened, one-piece heat-pressed lining guard against light rain and contain spills for easy cleaning.
• Organized storage: Multiple side pockets, a large front velcro patch area and two metal hanging buckles provide spots for phone, charger, keys and small accessories.
• Comfortable transport: Well-padded shoulder strap and sturdy top handles make carrying heavy loads up to about 10kg more comfortable and stable.

Who It's For

The GLENKEY lunch box is best for adults who need a versatile cooler that doubles as a meal carrier and soft cooler for work shifts, picnics, or short road trips. It suits people who pack multiple containers, drinks and snacks and want separate storage for wet and dry items.

It is less suitable for ultralight day hikers or anyone who needs rigid cooler performance for multi-day camping; those users should consider a hard-sided cooler. Buyers who expect flawless zippers in every unit should note there are mixed reports on zipper strength.
