  Product Description
The Outwell Caldera Lux sleeping bag combines practical warmth with genuine comfort for campers who want better sleep without carrying excessive weight. At 1.4kg with a pack size of just 22 x 18cm, it fits easily into rucksacks or car boots. The 100% recycled polyester Isofill Premium filling mimics down's loft without the moisture issues, while the 190T brushed lining feels soft against skin rather than cold and clammy. The unique V-shaped stitching pattern isn't just decorative, it reduces cold spots by preventing filling migration more effectively than traditional horizontal baffles. The L-shaped two-way zip opens from either end, useful when you need foot ventilation without exposing your upper body to cold air.

Outwell rates this bag with a comfort temperature of 8°C for women and a lower limit of 4°C for men, placing it squarely in the spring through autumn category for UK camping. The -10°C extreme rating exists for survival situations only, not comfortable sleep. The removable pillow is properly integrated rather than a loose add-on, staying in place through the night. The comfort hood cinches around your head to retain warmth, while an internal pocket keeps phones or headtorches accessible. The full-length zip baffle prevents cold air sneaking through the zipper teeth, a detail cheaper bags often skip. The 20D shell fabric keeps weight down but won't withstand rough treatment as well as heavier materials.

This bag measures 220 x 80cm and suits people up to 190cm tall comfortably. The left-side zip means it won't pair with another Caldera Lux to create a double unless you find the right-zip version. The entire construction is PFAS-free, meeting current environmental standards without using persistent chemicals for water resistance. The cap compression sack compresses the bag smaller than stuff sacks, though you'll need to pack it loosely between trips to maintain loft. Being fully synthetic means it dries faster than down if it gets damp and continues insulating when wet, making it more forgiving for less experienced campers or changeable British weather.

Frequently Asked Questions

What temperature range is the Outwell Caldera Lux sleeping bag suitable for?
The Outwell Caldera Lux has a comfort temperature rating of 8°C for women and a lower limit of 4°C for men according to EN temperature testing standards. This makes it suitable for spring, summer and autumn camping in the UK. The extreme rating of -10°C is for survival situations only and not for comfortable sleep. This bag works best from April through October in typical British camping conditions.
Can I zip two Outwell Caldera Lux sleeping bags together to make a double?
The Caldera Lux comes in left-zip configuration. To create a double sleeping bag, you would need one left-zip and one right-zip version as the zips need to be on opposite sides to connect. The L-shaped zips allow pairing when you have both versions, running down the side and across the bottom. Two left-zip bags cannot be zipped together.
What makes Isofill Premium filling different from standard synthetic fills?
Isofill Premium uses 100% recycled polyester with hollow fibres that trap air more effectively than solid synthetic fibres, creating down-like loft and warmth. The V-shaped bonded stitching pattern in the Caldera Lux prevents this filling from migrating and creating cold spots, which is a common problem with looser synthetic fills. The recycled polyester construction means this filling continues insulating when damp and dries faster than natural down, making it more practical for UK weather conditions.
How tall do you need to be to fit comfortably in the Outwell Caldera Lux?
The Caldera Lux is designed for people up to 190cm tall. The sleeping bag measures 220 x 80cm overall, giving 30cm of extra length beyond the stated body height for the foot box and hood area. People between 175cm and 190cm will find it most comfortable. If you are significantly shorter than 175cm, you may find excess bag length at your feet. If you are taller than 190cm, the bag will feel cramped and the comfort hood may not sit properly.
What does PFAS-free mean for the Outwell Caldera Lux construction?
PFAS-free means the Caldera Lux is manufactured without per- and polyfluoroalkyl substances, which are persistent chemicals previously used for water and stain resistance in outdoor gear. These chemicals do not break down in the environment and have been linked to health concerns. Outwell has removed PFAS from the Caldera Lux construction while maintaining performance through alternative materials and construction methods. This meets current EU regulations and environmental standards for camping equipment.
How should I store the Outwell Caldera Lux between camping trips?
Store the Caldera Lux loosely in a large breathable storage bag or hung up rather than in the compression sack between uses. Keeping synthetic sleeping bags compressed for long periods can damage the loft and reduce insulation performance. The cap compression sack is for transport and packing only. Store the bag in a dry location away from direct sunlight. Before storing, make sure the bag is completely dry to prevent mildew growth on the polyester materials.
