Coolflask Long-lasting Insulated Water Bottle, 87 oz, Three Lids, Samurai Cyan

The 87 oz Coolflask insulated water bottle pairs a wide-mouth stainless steel body with triple-layer, copper-plated vacuum insulation. It’s designed to keep drinks cold for up to 48 hours or hot for up to 24 hours, while the sweat-proof coating helps keep the outside dry in your hand or bag.

Three lid styles let you choose how to drink and carry it: a straw lid for sipping cold drinks, a spout lid for hot beverages, and a screw-on lid with a flip-up handle for carrying and adding ice. The set also includes a carrying bag with a pouch and shoulder strap, plus two straws and a straw brush.

At a glance

The stainless steel bottle is BPA-free and reusable, with a capacity suited to days when you want fewer refill stops. Its 12W x 35H centimetre dimensions give you a clear sense of its footprint, while the wide mouth makes adding ice more convenient. The triple-layer insulation is the key feature for anyone switching between chilled water and hot drinks throughout the day.

The included carry bag and shoulder strap make it easier to bring along for a road trip, a hike, a camping outing, or a day at a sports event. Customer feedback often highlights the bottle’s size, lid choices, and cold retention. Some buyers also report mixed experiences with durability and lid sealing, so the different opinions are worth keeping in mind when choosing how you’ll carry it.

How to use it

Choose the straw lid for sipping cold water, or the spout lid when drinking hot beverages. The screw-on lid with flip-up handle offers another way to carry the jug and makes adding ice easier through the wide mouth. The bottle is intended for water, coffee, juice, soup, and tea, so it can serve as a large water jug or a container for drinks and soup on the go.

For everyday outings, pack it in the carrying bag and use the shoulder strap to transport it. Avoid putting the bottle in a freezer or microwave, and don’t use it for soft drinks. Take care when handling hot liquids to reduce the risk of scalding.

Who it’s for

This bottle suits adults who want a high-capacity reusable option for outdoor activities, travel, sport, or a long day away from home. Its three lid styles offer a practical choice between sipping through a straw, drinking from a spout, and carrying the bottle by its flip-up handle. If you’re comparing it with a smaller bottle that’s easier to tuck into a bag, the Coolflask’s appeal is its 87 oz capacity and included carry setup for longer outings.

A solid pick if you want one large insulated bottle for both cold and hot drinks, with lid options for different ways of drinking. Buyers’ views on sealing and durability are mixed, while size, portability, and temperature retention are commonly appreciated.
