  • Lakeland Thermoflex Cool Bag 20 Litre

    Perfect for long journeys and summertime trips to the beach – carrying enough to keep the whole family well-fed all day long – our ThermoFlex Bag doesn’t just work like a cool bag to keep a picnic lunch cool for hours on hot days, it can also keep hot dishes warm when you’re travelling to a Jacob’s Join-style party with your home-cooked contribution!

    Keeps things cold for hours

    Don’t be deceived by the super-soft construction and dark colouring, this Flectalon-lined cool bag offers impressive keeping-things-cold performance as well as easy-to-pack flexibility. Ideal for squishing into luggage when you’re going on a self-catering holiday, it will also help your lunch keep its cool on the hottest beach, or carry a bagful of freezer shopping home.

    Keeps things warm

    If you live just a bit too far away for internet takeaway deliveries to reach you, this bag will hold all the warmth inside so you can get the family’s meal home while it’s still at its best. And if you’re cooking supper for a friend in need, or carrying a hot dish to a party, the ThermoFlex will help you get it there while it’s still piping hot.

    Stylish design

    Smartly styled in navy blue, this soft, squishy bag is also tough and lightweight, making it perfect to accompany a family outing or shopping trip without weighing anyone down. For added convenience, the bag features an adjustable shoulder strap and strong webbing handles to make it comfortable to carry.

    Easy to fold up for storage between supermarket trips and picnics, the bag can easily be hand-washed if anything is spilled while you’re out and about.

    Space-age insulation

    Flectalon was created by physicists at the University of Cardiff – developed as part of the NASA space research programme for astronauts’ clothing. Heat-reflective and thermal, the fabric has multiple layers of thin, aluminised fibres that efficiently reflect infra-red heat and combine this heat reflection with trapped air insulation for optimum insulation. Much prized by mountain rescue and lifeboat crews because it’s brilliantly effective at bringing anyone at risk of hypothermia back to a normal temperature, this washable fabric is also used to make super-lightweight quilts for poorly babies in hospital.

    20 litre. 45 x 18 x 30cm H.

    "Excellent product"

    I bought one of these 15 plus years ago (the model without the extra space in the lid) and it has served us well. It is used every summer for transporting cold/frozen food on holiday, been to the beach (washes well!), on picknicks and used for frozen food when the freezer is on the blink.. It's lightweight and squishy and you can pack loads in.
