Keeping bait and food cool in the summer sunshine, especially abroad, can be a struggle - but not with this cavernous cooler that can keep ice intact for almost a week...

Long summer sessions can be the most glorious times on the bank - but keeping food and bait cool is a real headache.
Foil-lined cool bags are great for food and short sessions, but if you're travelling to France or enjoying a long domestic session then you need something more substantial, especially if you're taking frozen boilies.
Enter this beast, the Coleman 100QT Xtreme Cooler.
If you know anything about general outdoor life beyond fishing then Coleman will be a familiar brand, and its coolers are legendary. Vintage examples still fetch big money so you could even look at this as a potential investment piece.
With a massive 91-litre capacity (that's 130 cans of Coke!), you could almost curl up inside this trunk-sized container.
Initially, it appears like just a big plastic coolbox (it's 92cm long and weighs 7.6kg), but there are some nifty hidden features. Firstly, the polyurethane insulation used is crucial to its performance and particularly dense, filling the internal cavity without air gaps.
There's increased insulation in the base and top, where most cooling is lost in traditional rigid coolers, and the design of the Xtreme includes moulded feet to elevate the cooler from the ground for improved efficiency.
If you fill this cooler with loose ice, there's a nifty drain plug to takeaway the water after use, but Coleman says the Xtreme can keep ice intact for up to five days.
We've tested it extensively over sessions of up to 48 hours and can well believe this claim. For a freestanding cooler without any battery or electric input, that's a really attractive feature for the long-session angler.
Away from the scientific wizadry, this coolbox also makes a great seat! Even the biggest of people can sit safely on the lid, with easy access to the four cup holders.
It is undeniably a large item, but obviously you can stuff a lot inside it. The rise-and-fall handles on either end are robust and easy to use. The lid only has a single retaining strap where we'd probably have preferred two for added security, but the overall build quality is bomb-proof.
It's not cheap, but the Xtreme can be bought for well under the recommended retail price, and there are smaller options in the range.
For the long-session angler or for groups heading to France, this is the ultimate cooling device.
