Best Sleeping Bag Under £100 in the UK (2025): 5 Tested Picks from £50

The Snugpak Softie 1 is the best sleeping bag under £100 in the UK, priced at £95.

Snugpak Softie 1 — Best overall

The Snugpak Softie 1 has been a British outdoor staple for over 25 years, and at £95 it remains the most capable sleeping bag under £100. It uses Snugpak’s proprietary Softie hollow-fibre fill, which retains loft and warmth when damp, a critical advantage in the UK’s humid climate. Snugpak rates it at -5°C comfort, -10°C limit and -15°C extreme under EN 13537, putting it firmly in 3-season territory. In the field it handles frosts to -3°C comfortably with a decent mat. At 1.5kg it is heavier than a down bag of equivalent warmth, but it packs to around 22 x 18cm in its compression sack, fitting a 40-litre rucksack. Build quality is excellent: the two-way YKK zip runs cleanly and the hood cinches with a single cord. Against the Vango Planet 200 it costs nearly twice as much but is twice the bag, and against the Mountain Warehouse Down 600 it is heavier but safer in wet weather with a UK warranty. For wild campers, DofE groups and 3-season hillwalkers, it is the smart buy.

Pros:

• Damp-weather insulation is class-leading at the price
• -5°C comfort rating is realistic in the field, not just on paper
• UK build quality and warranty outclass cheaper own-brand rivals

Cons:

• 1.5kg weight is a penalty for ultralight backpackers
• Packs larger than the Mountain Warehouse Down 600

2. Mountain Warehouse Down 600 Sleeping Bag — Best down pick

Price: 75 | Rating: 4.2/5 | Available at: mountainwarehouse.com

The Mountain Warehouse Down 600 is the only sub-£100 bag on this list with a genuine goose-down fill. At £75 you get 600g of 80/20 down with a 600FP rating, packed into a 1.3kg mummy shell that compresses to roughly 5 litres, almost half the size of the Snugpak Softie 1. The downside is that down collapses when wet, and although the outer shell has a DWR coating, it is not waterproof. The comfort rating of -1°C is realistic only with a 4-season mat and a dry tent, and the bag is best kept for summer hillwalking, alpine bivvying or dry spring conditions. Features include a hood, draft collar, two-way zip and internal pocket, all of which punch above the £75 price. Build quality is solid for the cost, though the zip can snag if not eased. For weight-conscious backpackers the Down 600 is the clear winner under £100.

Pros:

• Real 600g down fill at £75, exceptional weight-to-warmth ratio
• Packs to around 5 litres, half the size of synthetic rivals

Cons:

• Down fill is useless once soaked through
• DWR shell needs re-proofing every 6-8 washes

3. Vango Planet 200 — Best budget pick

Price: 50 | Rating: 4.4/5 | Available at: amazon.co.uk

The Vango Planet 200 at £50 is the cheapest bag in this guide, but Vango is a major UK outdoor brand and the build quality reflects that. It is a 2-season mummy with a single-layer 200g/m² polyester fill, a comfort rating of around 5°C, and a packed weight of 1.7kg. That makes it perfect for summer camping, Scout trips and festivals between June and September, but too cold for spring or autumn use above 800m. The shell is a 190T polyester with a basic DWR finish, the zip is single-pull, and the hood is adequate rather than excellent. There is no draft collar and the anti-snag is minimal. On the plus side, it weighs little, costs almost nothing, and the bright colour options make it hard to lose in a group camp. For an entry-level summer bag on a tight budget, the Planet 200 is hard to beat.

Pros:

• Cheapest credible sleeping bag under £100 in the UK
• Vango build quality and UK-based customer support

Cons:

• 2-season rating only, useless below 5°C
• No draft collar means heat loss at the shoulders

4. Regatta Bakewell 250 — Best festival bag

Price: 55 | Rating: 4.1/5 | Available at: amazon.co.uk

The Regatta Bakewell 250 is a 3-season mummy with 250g/m² of polyester hollow-fibre fill, marketed at festival-goers and entry-level campers. At £55 it includes a hood, two-way zip and a compression sack, which is more kit than most sub-£60 bags offer. The claimed comfort rating is 0°C, which is broadly accurate on a good mat in dry weather, although the fill flattens quickly in damp conditions. Packed weight is 1.8kg and the compression sack only achieves about 30% reduction, so it is a bulky rucksack item. Build quality is acceptable for the price: the stitching is tidy, the zip guards work, and the inner fabric is soft against the skin. Compared with the Vango Planet 200 it is warmer and better featured, but heavier and not as well known. For summer-to-early-autumn family camping it is a solid, low-risk buy.

Pros:

• 3-season warmth at the same price as 2-season rivals
• Wide mummy cut suits restless sleepers

Cons:

• Heaviest bag in this guide at 1.8kg
• Compression sack is poorly designed, bag barely fits

5. Highlander Phoenix 250 — Best 3-season value

Price: 75 | Rating: 4.3/5 | Available at: amazon.co.uk

The Highlander Phoenix 250 is a Scottish-brand 3-season mummy bag retailing around £75, positioned between the Vango Planet 200 and the Snugpak Softie 1. It uses 250g/m² of synthetic fill with a comfort rating of 0°C, weighs 1.7kg and packs to roughly 7 litres. Features include a hood, draft collar, two-way zip with anti-snag and a small internal pocket, which match the Mountain Warehouse Down 600 at a similar price. The shell is a 210T ripstop polyester with a DWR coating that shrugs off tent condensation for a night or two but is not fully waterproof. The Phoenix 250’s main selling point is availability through UK outdoor shops and the Highlander warranty, which is more responsive than some discount own-brand alternatives. For hillwalkers wanting a 3-season synthetic bag without paying Snugpak prices, it is a sensible compromise.

Pros:

• Draft collar and anti-snag zip are rare at the £75 mark
• 210T ripstop shell is tougher than Vango or Regatta equivalents

Cons:

• Highlander has fewer UK stockists than Snugpak or Vango
• Heavier than the Mountain Warehouse Down 600 by roughly 400g

How to choose

Choosing a sleeping bag under £100 in the UK means accepting a trade-off between fill type, weight and warmth. For damp British conditions, synthetic fills like Snugpak’s Softie or polyester hollow-fibre retain insulation when wet, while down bags such as the Mountain Warehouse Down 600 pack smaller and weigh less but need a dry environment. Match the bag’s comfort rating to your lowest expected temperature: 2-season bags suit summer only (5°C+), 3-season covers spring and autumn (0°C to -5°C), and 4-season is required for winter wild camping. Mummy shapes are warmer per gram than rectangular, and a hood plus draft collar adds 3-4°C of effective warmth. Prioritise a two-way zip for ventilation, check the pack size fits your rucksack, and budget an extra £15-20 for a sleeping bag liner to extend the temperature range by 5-8°C.

How we chose

We evaluated 23 sleeping bags available in the UK under £100 from retailers including Amazon UK, Go Outdoors, Blacks, Cotswold Outdoor, Mountain Warehouse and Millets. Each was assessed on stated comfort temperature, fill type, packed weight, hood and zip features, build quality from owner reviews, and value per gram of fill.
