Features

Recycled, water-repellent, windproof Pertex® Quantum Pro shell fabric
700 fill European Grey Duck down, sourced from producers that do not live-pluck or force-feed the birds
Ergonomic fit and proportional differential cut (liner is shaped smaller than the shell) for efficient thermal performance while maintaining comfort
Downshift function for enhanced heat distribution: the all-round, H-shaped down chambers allow the down to be 'shaken upwards' as required and the sleeping bag to be adapted to the respective temperature conditions
Adjustable hood for warmth around your head
Adjustable active draft collar fits snugly around your neck to keep heat loss to a minimum
Thick draft tube and zip cover provide excellent heat retention
Anti-snag stiffener ensures smooth zip operation
3D triangular footbox with 11 individual down-filled baffles eliminates cold spots
Glow-in-the-dark zip pulls with large zip garage for comfort
Bartack reinforcements where necessary for enhanced durability
Infoprint inside the bag provides technical information including temperature ratings
Comes with a sling storage bag with carrying strap and waterproof drybag
Loops at the foot end so you can secure your bag while airing without risk of it being blown away by wind

Expert Opinion

Performance and Comfort in a Lightweight Package

"The Spark 7 is one of the more compact sleeping bags on the market. It is really comfortable with the 3/4 zip and even the little features of the plastic flaring that goes over the zip to stop it from catching the fabric and making it more comfortable for sleeping. I find while this bag is rated to 7 degrees, with a small amount of clothing on during the night it is quite comfortable down to 5 or 6 degrees overnight temps."
