  Product Description
The Outwell Constellation Lux Double sleeping bag targets couples and families who camp across spring, summer and autumn conditions. It measures 230cm long by 160cm wide, providing proper room for two adults without that cramped feeling you get with standard double bags. The outer shell combines 85% polyester with 15% nylon for durability, while the 200 thread count cotton lining stays comfortable against skin throughout the night. Inside sits 3,150g of Isofill Premium recycled polyester filling, which keeps you warm down to 0°C comfort rating for women and -6°C limit rating for men.

This bag works as a double, zips apart into two separate singles, or opens completely flat as two duvets for flexible use. The YKK two-way L-shaped zipper includes auto-lock functionality, and there's a full-length zip baffle preventing cold air sneaking through. Both users get a built-in removable pillow, though pillow comfort remains subjective and some folks prefer bringing their own. Corner liner attachment loops let you secure a sheet inside if you want that home-bed feeling. The face baffle and zip-off hood provide adjustable warmth around your head, whilst PFAS-free construction means no nasty chemicals.

At 5.8kg packed weight and 51cm x 45cm pack size, this isn't a lightweight backpacking option. The compression carry bag with extra-large opening makes stuffing easier than wrestling with traditional narrow bags. The 3-4 season rating suits UK camping from April through October, but you'll want proper winter gear for colder months. Outwell rates this with a -24°C extreme survival temperature, though that's purely for reference and not remotely comfortable. The cotton lining needs more careful storage than synthetic alternatives to prevent mildew, so keep it properly aired and dry between trips.

Frequently Asked Questions

What temperature range works for the Outwell Constellation Lux Double sleeping bag?
The bag has a 0°C comfort rating for women and -6°C limit rating for men according to EN13537 testing standards. This makes it suitable for UK camping from April through October in typical conditions. The extreme rating of -24°C represents a survival temperature where hypothermia becomes likely, not a comfortable sleeping temperature. For winter camping below freezing, you need a bag with lower comfort ratings.
Can the Outwell Constellation Lux Double split into two single sleeping bags?
Yes, the YKK L-shaped zippers allow you to separate this into two individual single sleeping bags without hoods. You can also open it completely flat to use as two separate duvets. This flexibility means couples can sleep separately when temperatures differ or use the singles for different trips. The bags zip back together when you need double configuration again.
How do you care for the cotton lining in the Constellation Lux Double?
The 200 thread count cotton lining needs proper airing after each trip to prevent mildew development. Hang the bag loosely in a dry space rather than storing it compressed long-term. Cotton absorbs moisture more readily than synthetic linings, so you must dry it thoroughly before packing away. Store in the large mesh storage sack rather than the compression bag between camping seasons. Spot clean when possible and follow Outwell washing instructions when full cleaning becomes necessary.
What does PFAS-free mean for the Outwell Constellation Lux Double?
PFAS-free construction means Outwell manufactures this sleeping bag without per- and polyfluoroalkyl substances, which are synthetic chemicals linked to health and environmental concerns. Many outdoor products traditionally used PFAS for water and stain resistance, but manufacturers now avoid these compounds. The Constellation Lux achieves its performance through alternative materials and construction methods. The filling also uses 100% recycled polyester rather than virgin materials.
Will the Outwell Constellation Lux Double fit inside a standard tent?
At 230cm long by 160cm wide when laid flat, this bag needs a sleeping area of at least 240cm by 170cm to avoid touching tent walls. Most 3-person tents and larger provide adequate floor space, but compact 2-person tents often measure too narrow. The bag works well in 4-person family tents, touring tents, and bell tents where floor space exceeds the bag dimensions. Check your tent's internal sleeping area measurements before purchasing to confirm compatibility.
How does Isofill Premium filling compare to down insulation?
Isofill Premium uses recycled polyester fibres that maintain insulation when damp, unlike down which loses warming ability when wet. Synthetic fills like Isofill weigh more and pack larger than equivalent down bags, but cost less and require simpler care routines. The 3,150g of Isofill in the Constellation Lux Double provides reliable warmth in typical UK camping conditions where morning dew and occasional rain make moisture resistance valuable. Down bags offer better warmth-to-weight ratios for backpacking but need careful moisture management.
