Large Capacity Waterproof Thermal Insulation Cooler Bag

This cooler bag is built for the kind of everyday use that involves moving food around — packed lunches, outdoor meals, short trips, picnics, that sort of thing. It's made from polyester, so it stays light despite having enough room inside for lunch boxes, drinks, snacks, and fruit. The outer surface has a waterproof-style finish too, which helps when there's light rain, spills, or just the general wear and tear of being handled outdoors.

There are two style options here. Style A leans toward a softer tote shape and comes with a purple bow detail on it, while Style B is more of a structured rectangular cooler with a front zipper pocket. Both share the same black body with purple webbing and trim, so they look related without being identical. The purple handles and the adjustable shoulder strap mean it can be carried either by hand or over the shoulder, depending on what's easier at the time.

Inside, the insulation helps slow down how quickly temperatures shift, so food and drinks stay cooler — or warmer — for a reasonable stretch during regular use. The zipper keeps everything closed up properly, and the opening is wide enough that packing containers, cans, or bottles in and out isn't a hassle.

Sizing differs slightly between the two. Style A comes in around 33 / 21 × 23.5 × 15.5 cm and weighs about 0.21 kg, while Style B is roughly 31 × 23.5 × 17 cm and weighs about 0.37 kg per piece. That gives a bit of flexibility depending on whether someone needs something more compact or a bit more storage room.

On the production side, this bag fits fairly well into retail lines, promotional programs, private label collections, outdoor product ranges, or general food storage categories. Customization is available too — logo labels, front patches, color matching, zipper style, shoulder strap design, handle structure, lining material, packaging, and size adjustments can all be discussed depending on the project.

We build this with attention to practical structure — solid stitching, zippers that don't stick or catch, and sizing that stays consistent across batches. As a factory that works with cooler bags regularly, the goal is keeping it easy to use day after day without the quality dropping off over time.

Product Features

Waterproof-Style Polyester Fabric

The outer material is polyester, which keeps the bag light while still holding its shape. The surface has a waterproof-style finish, so it handles light spills, condensation, or general outdoor moisture without much trouble — useful when it's being used for food and carried around daily.

Thermal Insulation Structure

There's an insulated lining on the inside that helps keep food and drinks at a steadier temperature for a while. Works fine for packed lunches, drinks, fruit, snacks, meal containers, or food taken along for a picnic.

Two Practical Bag Styles

This model comes in two versions:

• Style A — a softer tote-style cooler with a bow detail
• Style B — a more structured rectangular cooler with a front zipper pocket

Both are meant for household storage, outdoor use, and general daily carrying, just with slightly different looks depending on preference.

Comfortable Carrying Design

Top handles come standard, along with an adjustable shoulder strap, so there's flexibility in how it's carried. Style B also has a padded section on the handle, which makes gripping it more comfortable during longer carrying or travel.

This bag fits into a range of everyday situations:

• Daily lunch carrying
• Picnic food storage
• Outdoor meals
• Short trips
• Drinks and snack storage
