Sleeping Bags

Sleeping Bags for UK Camping and Backpacking

The right sleeping bag depends on how you camp, how cold you sleep, and how much you carry. Backpackers need low weight and small pack size. Tent campers need reliable warmth across a full UK season. Hammock campers need a centre-zip design. This collection covers all three — with synthetic fill across most of the range for UK wet-weather performance, and one down option for backpackers who prioritise weight above everything else. Browse by Robens, Highlander, DD Hammocks, Bushmen, and Kombat UK.

Robens Sleeping Bags – Ultralight Down to Winter Expedition

Robens is the lead brand in this collection and the strongest choice across every temperature range. The Scoria UL is the only down sleeping bag here — ultralight, packing to a fraction of the size of any synthetic equivalent, rated from +6°C through to -6°C. Down loses insulation when wet, so it suits backpackers who keep their kit dry; for everyone else, the synthetic Robens ranges are the more practical choice in UK conditions. The Couloir range covers synthetic fill from -4°C to -15°C — both the Couloir 350 and Couloir 750 are confirmed centre-zip, making them suitable for hammock camping as well as tent use. The Serac range covers winter and expedition use at -14°C and -20°C. The Spire and Moraine ranges sit in the middle ground, covering three-season tent camping from +11°C down to -9°C.

Highlander Sleeping Bags – Summer to Four-Season at Accessible Prices

Highlander covers the practical, accessible end of the collection. The Defender range is the workhorse — three to four-season synthetic mummy bags with a water-repellent ripstop shell, from 1°C comfort on the Defender 350 through to the Defender 450 for four-season use. The Trekker 150 and Trekker 250 are lightweight compact mummy bags with integrated bug nets and a confirmed centre-zip, suited to summer backpacking and hammock-compatible use. The Phoenix range adds a practical system: the Spark 150 and Flame 400 connect together via a built-in hook and loop system to create a five-season combination, and both include a waterproof boot liner. The Sleepline range covers comfort-focused mummy, envelope, and double bag options for general camping where pack size is less of a priority. The Challenger 400 covers winter use at -5°C comfort and -15°C extreme.

Centre-Zip Sleeping Bags for Hammock Camping

Getting in and out of a side-zip sleeping bag in a hammock means wrestling with the zip in a confined, suspended space. A centre-zip bag opens from the top and makes entry and exit straightforward. The bags in this collection confirmed as centre-zip are the Robens Couloir 350 and Couloir 750, the DD Jura 2, and the Highlander Trekker 150 and Trekker 250. For top quilts and underquilts designed specifically for hammock camping, browse the Hammock Camping Insulation collection.

DD Hammocks Sleeping Bags for Hammock and Bivi Camping

DD Hammocks design their sleeping bags with hammock camping in mind. The DD Jura 2 is a centre-zip bag built to work inside a DD hammock — the zip position means you can get in and out without the contortions a side-zip bag demands in a suspended sleeping position. The DD Scarba is a lighter side-zip bag with a waterproof footbox, suited to tent and bivi camping.

Double Sleeping Bags for Couples Camping

The Highlander Sleepline Double range covers couples camping together. The Sleepline 350 Double suits two to three-season use at 5°C comfort; the Sleepline 250 Double suits summer and warmer conditions at 8°C comfort. Both are envelope-style bags with a full-length two-way zip.

Bushmen Modular Bivvy and Sleeping Bag Systems

Bushmen take a different approach. The HIDEOUT is a multifunction insulated bivvy that also works as a rain poncho and hammock underblanklet — on its own it is a summer bag at +14°C, but paired with a WALKER as an inner liner it extends to +5°C comfort, giving you a modular system that adapts across seasons without buying two separate bags. The WALKER 1 is a summer bag at +13°C comfort for men, the WALKER 3 covers three-season use at +6°C — both convert to a vest or poncho and work as a liner inside the HIDEOUT system. Available in L and XL lengths.

Budget Sleeping Bags UK – Kombat UK

Kombat UK sit at the accessible end of this collection and offer genuinely good bags for the price. The Cadet Sleeping Bag is a water-resistant synthetic mummy bag rated to 0°C comfort, with a bivi housing built into the compression sack — a practical feature that adds real versatility at a price point that makes it an easy first choice for anyone who needs a reliable three-season bag without the outlay of a premium brand.

Sleeping Bag Questions Answered

What temperature rating sleeping bag do I need for camping in Scotland?

For three-season camping in Scotland — spring, summer, and autumn — a comfort rating of 0°C to -5°C covers most conditions, including cold nights at altitude and in exposed glens. Winter camping in Scotland needs a comfort rating of -10°C or colder. Always use the comfort rating, not the limit rating — the limit rating is the temperature at which a cold-sleeping adult male can survive, not sleep comfortably.

Is down or synthetic fill better for UK camping?

Synthetic fill is the more practical choice for most UK camping. It maintains insulation when damp, dries faster, and costs less than equivalent down. Down offers a better warmth-to-weight ratio — worth it for backpackers who can keep their kit reliably dry. The Robens Scoria UL is the only down bag in this collection; every other bag uses synthetic fill.

Which sleeping bags are suitable for hammock camping?

Centre-zip sleeping bags are compatible with hammock use because the zip opens from the top rather than the side. In this collection, the Robens Couloir 350 and Couloir 750, the DD Jura 2, and the Highlander Trekker 150 and Trekker 250 are confirmed centre-zip designs. For dedicated hammock insulation, browse the Hammock Camping Insulation collection.

What is the difference between a mummy and an envelope sleeping bag?

A mummy bag tapers from shoulders to feet — it retains heat more efficiently and weighs less, making it the right choice for backpacking and cold-weather camping. An envelope bag is rectangular and gives more room to move — better for car camping and warmer conditions where heat retention is less critical. The Highlander Sleepline Envelope and Double bags are the envelope options in this collection.
