The opinion of Aventure Nordique

3 season sleeping bag with comfortable tapered rectangular shape. This design offers a good compromise between the comfort of a generous cut shape and warmth of a closer fit. A full length side and foot zip allow the Trek TkII to be opened out into a full duvet for use indoors and warm weather.


  • Tapered rectangular for more space and comfort than a traditional mummy bag

  • RDS 650+ Loft ULTRA-DRY Down offers excellent insulation and compressibility

  • Lightweight fabrics for reduced weight and bulk

  • Vertical chest baffles prevent down migration and cold spots

  • Two-way #5 YKK side and separate foot zip allows bag to double as a quilt and provides extra ventilation options

  • Oversized zip draft tube with anti-snag materials

  • Large internal security pocket

  • 3D side-wall baffle maximises down insulation right to the edge of the bag

  • 3D hood draws in tight when needed

  • Soft touch 20D lining fabric is lightweight and highly breathable, durable 30D Nylon shell

  • Includes Ultra-Sil Compression Bag for compact storage

  • This bag is designed to pair with another
