The details

Experience unparalleled comfort and versatile performance with the Sea to Summit Trek TKI 30 Degree Down Sleeping Bag TK1 - Reg. Designed for avid backpackers and campers, this sleeping bag features a wider-cut tapered rectangular shape that offers more space and freedom of movement compared to traditional mummy bags, ensuring a restful night’s sleep in the wild.

Constructed with premium ULTRA-DRY Down® 650+ Loft, this sleeping bag delivers exceptional insulation, lightweight warmth, and superior compressibility, making it the ideal choice for cold-weather adventures. The vertical chest baffles and oversized draft tube prevent heat loss, while the 3D side-wall baffle maximizes insulation right to the edges, keeping you warm in temperatures as low as 5°C (comfort to -1°C).

Enjoy customizable ventilation with dual-zip system: fully unzip the side or footbox zippers to increase airflow, turn your sleeping bag into a cozy comforter, or cool off during warmer nights. The soft-touch 20D lining fabric is both breathable and durable, providing a comfortable sleeping surface even on extended trips.

Additional features include:

  • Relaxed fit for more sleeping positions and reduced cold spots
  • Internal security pocket for your essentials
  • Large internal security pocket for safe storage
  • Two-way YKK zippers for smooth operation and extra ventilation
  • Lightweight 30D Nylon shell and Ultra-Sil™ Compression Bag for compact storage and easy packing
