It is toasty warm and spec'd down to -11c. Under -5 I would suggest using a silk liner/thermals too, but then I feel the cold. It comes with a wash bag, a storage bag and a stuff sack. Everything is in excellent condition, the materials are very comfortable and hardwearing. 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. 3D side-wall baffle maximises down insulation right to the edge of the bag. 3D hood draws in tight when needed. Trek Tk3 has additional neck collar draft tube to seal and trap in all your warmth.
