Sleeping Bag vs Backpacking Quilt: OEX Sky High 700 and UGQ Bandit Compared

Introduction

Choosing between a sleeping bag and a backpacking quilt is one of the more consequential decisions in a lightweight sleep system. Both keep you warm, both pack into a stuff sack, and both are rated on the same temperature scales. The real difference is how they distribute insulation and how much freedom they leave you during the night.

This comparison looks at two specific options: the OEX Sky High 700, a conventional down sleeping bag with a hood and a full-length zip, and the UGQ Bandit Backpacking Quilt, a custom-made quilt rated to 20°F. They sit at similar comfort ratings but take very different routes to get there.

How a Sleeping Bag and a Quilt Differ

A conventional sleeping bag is an insulating cover that surrounds the body. Insulation runs across the top, down the sides and along the underside, with a full-length zip, a shoulder baffle and a hood that cinches down with drawcords and toggles. Once you are inside and zipped up, everything is sealed around you.

A quilt works differently. It has an open back and a closed foot box, so it covers the top and sides of the body while relying on an insulated sleeping pad beneath you for the bottom layer.

That design decision matters more than it first appears. Down that sits underneath a sleeping body is compressed by your weight, so it offers very little insulation. A quilt removes that material entirely, which means less bulk and less weight for the same comfort rating.

OEX Sky High 700 Sleeping Bag: Traditional Coverage

The Sky High 700 is a mummy-style down bag with 650 fill power insulation, a full-length zip, a shoulder baffle designed to hold heat inside, and a hood that can be pulled up and cinched. There is a generous layer of loft around the foot area. Weighing 1.3 kg in the version used over several seasons, it has a comfort rating of -6°C and holds that warmth in temperatures around -5°C.

The trade-offs are familiar to anyone who has slept in a bag. Movement is restricted once you are zipped in, getting out in a hurry takes some effort, and finding the toggles from inside is fiddly. The current Sky High 700 has been updated with a comfort rating of -2°C and a slightly lower weight, retailing around £179 with frequent sale pricing near £150.

UGQ Bandit Backpacking Quilt: Light and Adaptable

The Bandit is a custom-made quilt with 850 fill power down and a 20°F rating, roughly -6°C. Higher fill power means more loft for the same weight, and the difference is easy to see. In the long and wide size, 78 inches by 60 inches, it weighs 780 grams, though that figure includes an ounce of overfill in the regular baffles and foot box plus an optional shoulder baffle.

Getting in is closer to pulling a duvet over yourself than climbing into a cocoon. A snap system closes the quilt around the shoulders, and a dynamic tensioning system tucks the lower edge under your side to limit drafts. Pad straps are available to anchor the quilt, using small toggles that clip onto bungee cords fitted to the pad.

The zipper foot box is the feature that sets it apart. Undo the press stud, unzip the foot box, release the tensioners, and the quilt becomes a flat blanket. That makes it useful around camp in the evening, or as an extra layer over two people in a pinch. The shell is a charcoal grey fabric with a matching finish.

Weight and Packability Compared

The headline figure is straightforward: 1.3 kg for the sleeping bag against 780 grams for the quilt, at a similar comfort rating. Removing the insulation that would sit underneath you accounts for most of that gap.

Fill power plays a part too. An 850 fill power down lofts more than a 650 fill power down for the same weight, so the quilt reaches its warmth with less material. Custom choices affect the final number as well: adding overfill and a shoulder baffle pushed the -6°C quilt about 20 grams above a warmer -12°C version of the same design.

Temperature Ratings and Real-World Warmth

Both setups in this comparison land at around -6°C comfort, and both are intended to hold that warmth in genuine overnight conditions. Ratings are still personal. A cold sleeper and a hot sleeper can have very different experiences in the same bag on the same night, so it is worth researching a specific model before committing.

The practical difference shows up overnight. A sleeping bag holds warmth all around you and cannot easily be adjusted, which becomes uncomfortable for anyone who runs hot. A quilt lets you pull it over your shoulder when you cool down, or push an arm or a leg out when you overheat. Because there is no hood, a warm hat is a sensible addition on colder nights, and the -12°C version of the same quilt is more warmth than most UK trips need.

Custom Options and Value

The Bandit is built to order, which means length, width, colour, fill weight, baffle configuration and overfill are all choices rather than fixed specifications. That flexibility is the reason a custom quilt can be specified to your own measurements, and it is also the reason it costs more. Builds start around $250, and UK buyers may also face import tax and duty on top.

Budget routes look different in each category. For sleeping bags, synthetic fill brings the price down at the cost of weight and packed size. For quilts, the UK market remains limited, and the locally available options tend to be less warm than a custom down build.

Buying Advice: Which Setup Fits Your Trips

A conventional sleeping bag remains the simpler choice if you want insulation all around you, a hood attached to the bag, and a design you already know how to use. It is also the better starting point if you sleep cold.

A quilt suits backpackers who count grams, hot sleepers who need to vent heat, and anyone who values a piece of kit that doubles as a blanket at camp. It does depend on a decent insulated pad, since the pad provides the warmth beneath you.

Whichever direction you take, match the rating to the conditions you actually camp in, and factor in the extras: import charges on a custom build, a warm hat for a hoodless quilt, and a pad with enough insulation for the temperatures you expect. A bag or quilt that is far warmer than your trips require is weight and money spent for nothing.

Conclusion

Both of these sleep systems keep a sleeper comfortable to around -6°C, and the choice comes down to priorities rather than performance. The OEX Sky High 700 offers the enclosed, hooded coverage most campers grew up with, at a mainstream price. The UGQ Bandit Backpacking Quilt cuts the weight to 780 grams, adds the freedom to regulate temperature through the night, and converts into a blanket once the foot box is opened.
