The Circuit Down Sleeping Bag by Sea to Summit is the zip-it-up, open-it-out solution for adaptable warmth on every outdoor escape!
Boasting quality 650+ fillpower Ultra-Dry Duck Down and lightweight 20D fabric, this bag offers efficient packability and premium next-to-skin comfort night after night. Opens flat for airflow on warm nights or zips closed to lock in warmth when temperatures drop, while the wider, semi-tapered-rectangular shape and soft-touch liner enhance comfort no matter which position you sleep in.
The wrap-around zip lets you fully open the footbox for maximum venting and fine-tune airflow to regulate temperature, and hybrid box-baffle construction prevents down migration to eliminate cold spots for even warmth.
A YKK #5 coil zipper with anti-snag plough ensures smooth, jam-free operation, while a shaped collar and continuous down-filled draft tubes minimise heat loss for maximum retained warmth. ISO 23537 certification confirms dependable insulation performance for rated temperatures.
The Sea to Summit Circuit Down Sleeping Bag is the versatile, packable warmth solution for every alfresco sleep!
