- Recycled outer and inner fabrics
- 700 fill European Grey Duck down, sourced from producers that do not live-pluck or force-feed the birds
- Wide mummy shape increases freedom of movement while maintaining warmth
- 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 comfort hood with extra wide cut
- Adjustable draft collar reduces heat loss
- Thick draft tube and zip cover provide excellent heat retention
- Anti-snag stiffener ensures smooth zip operation
- Side arm exit for maximum flexibility: on the opposite side of the main zip, a zipped arm hole backed by a draft tube allows comfortable sitting while using both hands to hold a warm mug of tea or book
- 3D triangular footbox with 11 individual down-filled baffles eliminates cold spots Zip opening at the foot end allows you to transform the bag into a blanket or parka as well as adding ventilation options
- 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 packsack
- Loops at the foot end so you can secure your bag while airing without risk of it being blown away by wind
- Part of Exped's Trekking range designed with comfort and functionality over a wide scope of adventures and finely tuned for each season
- Carbon neutral: Exped measures, reduces and fully offsets CO2 from manufacturing and shipping this product through myclimate
