The Highlander Rayet 450 is a mummy-shaped synthetic sleeping bag that offers a lot of warmth for £79.99. It’s filled with 450g/m² of double-layer insulation and wrapped in a water-repellent ripstop shell, so it’s aimed squarely at people who want reliable warmth in damp British conditions without paying for down.
We’ve tested it across three seasons. I’ve used it on an August camp beside the Dee near Llangollen, with lows of around 7°C, and on an early spring trip in Mid Wales when temperatures fell to around 1°C. My colleague Sophie also took it to the Highlands near Inverness, sleeping on snow at -2°C.

Highlander Rayet 450 Temperature Rating: How Warm Is It?
Our testing backs up the -1°C comfort rating. I’ve been warm every night I’ve spent in it, sleeping in just baselayers, and Sophie stayed warm at -2°C in the Highlands. We used it with the Highlander Nap-Pak Arctic R11 sleeping mat, an impressive inflatable mat that offers amazing warmth at a low weight and low price too.
We haven’t tested it below that, though, and I wouldn’t want to push it much further. Below -1°C, colder sleepers will start to need extra layers, warm socks and a well-insulated sleeping mat.
At the other end of the scale, it’s too warm for hot summer nights. The two-way zip lets you vent it, and it never felt clammy, but this is a shoulder-season bag first and foremost. It’s at its best on chilly spring and autumn nights, and it can stretch into mild winter nights at valley level.
Comfortable and Roomy
Comfort is one of the Rayet 450’s biggest strengths. The lining has a slightly brushed feel rather than the sticky, plasticky texture of some budget bags, which makes a real difference if you climb in a little sweaty after a day on the hill. It’s comfortable even against bare skin.
The cut is generous too. I’m a wriggly sleeper who tosses and turns, and I never felt restricted. The full-length two-way zip is easy to work from inside thanks to a large pull, although it does snag occasionally – fortunately it’s quick and easy to unsnag and the material can withstand it well. There’s a neck baffle, plus an internal pocket that’s ideal for keeping a headtorch within reach at night. There are no glow-in-the-dark details, though.
It feels robust, and we’ve had no problems with stitching or shifting insulation. It’s a shame, however, that none of the materials are recycled.
Highlander Rayet 450 Weight and Pack Size
This is where the Rayet 450 makes its compromises. At 2.09kg and 45 x 24cm packed, it’s heavy and bulky, and it takes up far more rucksack space than a down bag. The compression stuff sack makes packing away easy, but it adds weight of its own.
There are lighter, warmer alternatives, but they cost considerably more. The upside of the synthetic fill is that it copes well with damp, dries quickly and is easy to look after.
Best Uses for the Highlander Rayet 450
The Rayet 450 makes most sense for anyone who needs warmth in wet conditions on a budget. It’s great for car camping and campsite holidays, where the weight doesn’t matter, and it suits Duke of Edinburgh groups and cadets, particularly in wet places like Wales. Its tolerance of damp also makes it a good partner for a bivvy bag or hammock. I’d take it on a cold, wet spring or autumn multi-day trip, but it’s a little heavy for regular backpacking.
It stacks up well against similar budget bags. It’s warmer than Decathlon’s MT500 0°C trekking bag, although that’s a little lighter, and it’s warmer but slightly heavier than the Vango Nitestar Alpha 250S. Mountain Warehouse offers a warmer, cheaper bag at a similar weight, but Highlander has the stronger brand reputation in my opinion.
It’s worth noting that Highlander have a range of other options, including the cooler but lighter Rayet 350 and also the warmer but heavier Echo 400.
Verdict: Is the Highlander Rayet 450 Any Good?
The Highlander Rayet 450 brings a lot of warmth and comfort for £79.99. Its brushed lining is a pleasure to sleep in, the roomy mummy cut gives you space to move, and the water-resistant synthetic fill makes it a dependable choice for damp, chilly nights. It’s low-maintenance and should last for years too.
The trade-off is weight and bulk. At over 2kg, it’s not a bag you’ll want to carry far, and the unshaped footbox and lack of recycled materials lag behind pricier rivals.
If I were starting out on my Duke of Edinburgh award, or needed a warm, affordable bag for wet bivvies and campsite trips, I’d happily buy it. As a regular backpacker, though, I’d opt for something lighter and more packable.
