Best lightweight 3 season sleeping bags to keep you warm through the night

Even if you’re the sort of person who loves camping, the thought of waking up in winter’s frost is enough to have most folks rummaging for their hot water bottle and an Oodie.

Sleeping outside in sub-zero temperatures is no picnic, and unless there’s a very good reason - staying up to catch the Northern Lights in the Arctic Circle, or say, climbing Everest - we’re limiting outdoor winter adventures to bracing strolls and park walks.

So, that’s one season out - but what about the others? Late spring and early autumn can also be excellent times to head out and pitch up, with the bonus that camping sites are less busy than in peak season. You’ll also get to see nature’s transitional beauty up close, from hiking across woodlands flooded with daffodils, bluebells and daisies in the early half of the year, to trees changing from lush green to rich fiery hues as the months trickle into autumn.

The right kit is key. While the days might be bright and mild, cold can really kick in after sunset. For those dreaming of sleeping under starry skies, it’s all about investing in the bits and pieces that will keep you warm and toasty, no matter the weather.

After a decent tent, the next essential to have locked down is a sleeping bag. While liners and light tog designs are ideal for summer’s sweltering heatwaves, a three-season sleeping bag is a more logical purchase for those who plan outdoor trips on either side of the sunny season.

The good news is that there are plenty of them around, but which ones are really worth the cash? We’ve rounded up the best lightweight designs to keep your camping bulk to a minimum.

Aside from outdoor adventures, sleeping bags are also a good option to keep in caravans or have in the cupboard for spontaneous sleepovers.
