Quechua Arpenaz 10° Review: Budget 10°C Sleeping Bag That Actually Delivers
If you need a cheap, reliable sleeping bag for mild nights, Decathlon’s Quechua Arpenaz 10° is hard to beat. It’s ISO‑tested to a comfort 10°C (50°F) with a 5°C (41°F) limit, uses simple, durable synthetic insulation, and—crucially—zips to a second bag for couples. At ~1.3 kg and ~15 L packed volume, it’s a car‑camp staple rather than an ultralight trekker’s choice.

What we like
- Real, published ratings: Comfort 10°C, limit 5°C under ISO 23537 testing, so you know what you’re buying.
- Connects in seconds: Two Arpenaz 10° bags zip together—useful for couples or a parent + child.
- Easy care: Fully synthetic build is machine‑washable and forgiving of damp conditions.
- Value: Consistently one of the lowest‑price bags that still lists lab‑tested temps.
What to know before you buy
- Not for near‑freezing: At the 5°C limit, most campers will still feel cold without extra layers and an insulated pad.
- Bulky for backpacking: ~15 L packed volume and a rectangular cut make it best for car camping and festival use.
- No hood: Bring a beanie or pair with a hooded jacket on cooler nights.
Warmth & temperature truth (ISO 23537)
Decathlon publishes both comfort and limit ratings based on ISO 23537 lab tests. Comfort is the lowest temp where a relaxed sleeper feels neutral; limit is for a curled‑up sleeper and assumes ideal conditions. Translation: aim for 10°C nights, and treat 5°C as an emergency minimum, then add layers and an insulated mat.
Fit, build & materials
Rectangular cut (190 × 72 cm) with a full‑length zip—open it flat like a duvet in warmer weather. The shell, lining, and 300 g/m² wadding are 100% polyester. There’s no hood, which keeps price and complexity low. Two matching Arpenaz 10° bags can be twinned.
Packability & use case
At ~1.3 kg and ~15 L packed, this isn’t a trekking bag. It shines for car camping, sleepovers, road‑trip hostels, and festival weekends where durability, washability, and price matter more than grams.
Eco & care notes
Decathlon’s latest run uses dope‑dyed yarns and a mix of undyed fibres, helping shave CO₂ compared to prior versions. Machine‑wash cold; line‑dry if you can. A 5‑year warranty backs the product.
Better alternatives (by scenario)
- Hot‑summer nights: Quechua Arpenaz 20° — lighter/warmer‑weather sibling for balmy camps.
- Colder shoulder‑season trekking: Forclaz/Simond MT500 5°C Synthetic — mummy‑shaped, hooded, compresses smaller, true backpacking option.
- Couples set‑up: Arpenaz 10° Double — purpose‑built double that converts to a duvet.
Bottom line
For ~£25, you get a straightforward, ISO‑rated bag that’s comfortable around 10°C, easy to wash, and capable of zipping two together. If you’re camping from the car and watching the budget, the Arpenaz 10° is terrific value. If you plan on hiking below ~10°C or care about pack size, step up to a hooded, compressible trekking model.
