Sleeping bag Outwell 230506 semi-rectangular for adults, 2300×850 mm, max user height 195 cm, cotton/nylon/polyester (recycled), yellow

The Outwell Constellation Prime is a premium semi-rectangular sleeping bag designed for adults who want comfort and versatility while camping. It features an ultra-soft brushed outer fabric, a cotton lining and high-quality Isofill insulation. A built-in removable pillow adds convenience, and the bag can be unzipped to convert into a large duvet. It is supplied with a compression carry bag that has an extra-large opening for easier packing and transport.

Advantages

Comfort is prioritised through the soft brushed outer and cotton lining, while Isofill insulation provides consistent warmth without excessive bulk. The removable pillow increases sleeping convenience and the unzip-to-duvet function adds versatility for different temperatures and sleeping preferences. The compression carry bag with an extra-large opening simplifies packing and makes the bag easier to store and transport.

Suitable for

• Car and family camping trips where comfort is important
• Overnight stays at campsites or cottages in mild to cool conditions
• Campers who prefer a pillow integrated into the sleeping system

When it may not be suitable

This sleeping bag is designed for comfort rather than extreme cold-weather performance. It may not provide adequate insulation for very low temperatures or high-altitude expeditions. Also, the semi-rectangular shape offers more room than a mummy bag but is less thermally efficient for situations that require maximum heat retention.

How to use

Open the sleeping bag fully and place the removable pillow in the built-in pocket before use. Zip the bag closed around the sleeper, adjusting ventilation by partially opening the zip if needed. To convert the bag into a duvet, unzip fully and fold or lay flat as required. After use, clean according to the manufacturer's care instructions, dry thoroughly, and store in the compression carry bag for transport. Use the extra-large opening on the carry bag to insert the rolled or compressed sleeping bag more easily.

What to consider before purchase

• Intended temperature range and whether you need a bag for very cold conditions
• Preferred sleeping shape—semi-rectangular offers comfort but less thermal efficiency than a mummy bag
• User height to ensure the 2300 mm length is sufficient
• Care requirements for cotton lining and Isofill filling

Recommendations

Use the built-in removable pillow for added head support and unzip the bag when nights are warmer to use it as a duvet; store the bag dry and compressed for transport to maintain loft and packing convenience.
