A family cool bag designed to keep picnic food and drinks cold using multi-layered insulation. For families and festival-goers, the Thermos Family Cool Bag combines durable construction with practical storage for busy weekends. But does it stand up to rough handling and regular use?

⚡ At a Glance
  • Insulation Performance: Multi-layered polyethylene foam insulation slows heat transfer and retains chill
  • Best for: Families, picnickers and festival-goers who need reliable, portable cold storage
  • Not ideal for: Users who require a rigid powered cooler with exact temperature control

Multi-layered polyethylene foam and a PEVA heat-sealed lining combine to slow warming. A 500D polyester outer and semi-rigid inner floor deliver durable, shape-retaining performance.


Keeps contents cold longer – with multi-layered polyethylene foam insulation

Multiple layers of polyethylene foam trap pockets of air and reduce heat transfer by creating successive thermal barriers. The trapped air and foam density slow temperature equalisation between inside and outside.

Lower temperatures persist through day trips, helping chilled drinks and perishable food stay cooler for longer. Suitable for picnic days and outdoor events where refrigeration is unavailable.

Tough exterior for rough use – with 500D durable polyester fabric outer

A high-denier 500D polyester weave produces a dense, abrasion-resistant outer surface that resists tears and scuffs. The fabric stands up to repeated handling and abrasive contact.

Rugged shell copes with festival wear and family outings, keeping the cooler intact under heavy use. Long-lasting materials reduce the need for frequent replacement.

Stable base and easy organising – with semi-rigid inner floor, front pocket and adjustable shoulder strap

A semi-rigid inner floor maintains the bag's shape and prevents sagging under load, while a PEVA heat-sealed lining contains spills. An external zipped pocket and adjustable strap enable hands-free carrying and quick access.

Contents stay upright and protected, reducing crushed food and spilled liquids. Handy external storage and a comfortable strap make transporting and organising items straightforward.
