Description

Drier than regular down with more room than a regular mummy bag.

The Sea To Summit Traverse Xtll 12 Degree Down Sleeping Bag doesn't mind wetness, humidity, or tent condensation. The active 3D NanoShell technology with Nano DWR particles repel condensation from the outside, and the bag's unique siliconized polyester barrier beneath the shell prevents condensed body moisture from soaking back into the down from the inside. And if wetness still gets through all that, the Ultra-Dry Down handles it better than regular down.

  • With an EN comfort rating of 23F and a lower limit of 12F, this bag is best suited for spring through fall nights in the mountains or winter nights in milder climates or sheltered yurts
  • 850+ Ultra-Dry Down insulation features 90% down cluster premium European goose down that offers superb warmth and comfort
  • Ultra-Dry Down features a permanent Nano-level water-repellent polymer treatment that repels moisture, helps inhibit bacterial and microbial growth, dries faster, retains loft longer, and prolongs the overall life of the sleeping bag (as compared to untreated down)
  • Relaxed mummy convertible shape has a larger hood, broader shoulders, and a larger chest area (compared to regular mummy bags), and the full-length side and foot zip allow you to convert this bag to a duvet
  • Differential cut shell means the lining is cut smaller than the outer shell fabric so the insulation can expand outward for better lofting and to reduce cold spots
  • 3D side walls and offset baffles lead to less heat loss while side block baffles prevent down from migrating from the top of the bag to the bottom
  • Anatomically tapered foot box offers a more relaxed fit and plenty of unrestricted room when you sleep
  • 3D NanoShell fabric offers durability, breathability, and feels wickedly smooth and comfortable against your skin
  • Anti-snag zip-draft tube and anti-snag neck draft tube with dual elastic adjustment seal in warmth and block out the cold
  • Two-way YKK #5 zippers with separate foot zip for convenience
  • Medium-sized internal zip pocket stashes your headlamp or book
  • Includes lightweight Ultra-Sil compression bag, mesh storage cell, and laundry bag
