Although we weren’t keen on the very light (and perhaps a little too shiny) grey outer materials used to make the Halfords Urban Escape Tahoe, things definitely improve inside. The liner is a pleasingly soft mixture of Polyester and cotton. Unfortunately this choice of material rules out tumble-drying, but machine-washing at 30°C is still possible.

This sleeping bag is obviously mummy-shaped, but the Tahoe felt a little too cosy around the chest and shoulder areas, suggesting that this is a bag best suited to slender campers and caravanners. Or, perhaps more accurately, it’s perfect for tall and thin people, because the Tahoe is longer than most rival sleeping bags.

The compact pack-down size, impressive thermal properties and the pull-string hood are all further bonuses. 

This blue and grey cocoon shaped sleeping bag has a double layer of 300gsm filling. This is made of 60 per cent siliconised Hollowfibre, with 40 per cent Monofibre insulation. There’s a shoulder baffle, a ridged hood with a drawstring round it, so you can keep out draughts and avoid waking up with a stiff neck. There’s a two-way zip so you can cool your legs down at night if you need to, without getting chilly all over. If you like to keep your watch, earrings or valuables close to you, the good news is that there’s a hidden internal pocket just for that. 

The Tahoe weighs 1.7kg and is recommended for late spring, summer and early autumn use, though if you have a decent caravan heater this is pretty academic! 

The exact measurements are 230cm long and 80cm wide at chest height. Although it tapers at the foot, the construction of the bottom section allows room for your feet. 

There are Halfords stores all over Britain, so you shouldn’t have to travel far to buy sleeping bags there. You can find your nearest Halfords store here, use the ‘click and collect’ service or have products delivered to your door in 48 hours. 

Compare this mummy sleeping bag to others of a similar shape in our group test of 14 sleeping bags before you go to Halfords or a caravan accessory shop.

On the test bench we had several good but cheap sleeping bags, such as the Argos 927/6378 Regatta Single Mummy Sleeping Bag, £20, the Argos 144/1895 Highlander Sleephuggerz 250gsm Single Cowl Sleeping Bag, £25, shaped more like a pod than a mummy, as well as the Easy Camp Cosmos sleeping bag, £23. We also went pretty upmarket in search of the best caravan accessories for you, testing the high performance Robens Appalachion 1500 sleeping bag, £75, which was positively the warmest bag we reviewed. Then we tested its sibling, the Robens Trailhead 1500 sleeping bag, £50. 

A hybrid sleeping bag won our group test overall, combining the best of mummy bag style details with the roominess of a traditional rectangular envelope style of sleeping bag. This was the superb Outwell Campion sleeping bag, £25. 

Plus we looked at a couple of weird and wonderful snowsuit style sleeping bags! Find out why we think these are well worth considering in our reviews of the Musucbag Lite sleeping bag, £69, and the slightly cheaper Summit Motion Sac, £50. Yes, we’re well and truly in the space age with those two.

Finally, we looked at some lovely traditional rectangular sleeping bags, some of which borrow useful features from mummy sleeping bags, as you’ll discover in our reviews. We tested the SunnCamp Deluxe King Size Expression, £40, the Vango Serenity sleeping bag, £41, and two from Kampa – the Kampa Double Layer Garnet, £35, and its slimmer sibling, the more contemporary Kampa Single Layer Citrine, £43. Finally we tested the Coleman Vail Comfort sleeping bag, £53.
