Sea To Summit Altitude II Women’s Sleeping Bag

Incredibly versatile, the Altitude women's down sleeping bag is snug and cozy when it's cold, and cool and ventilated when the weather warms. Shaped to match your natural sleeping position the Altitude is both comfortable and light enough to carry anywhere.

Features

• ULTRA-DRY Down 750+ Loft 90% Down Cluster Premium Duck Down certified Responsible Down Standard (RDS)
• Thermolite® insulation in the foot section warms your feet instantly
• Free-flow zipper system: full-length YKK® #5 main side zip, half-length opposite side zip, and foot zip provides unparalleled ventilation and use as a comforter
• Internal pocket for phone / GPS / valuables
• Shaped hood, oversized draft collar, and zipper draft tube keep the cold out and the warmth in
• Includes lightweight Ultra-Sil compression bag and storage cell
• Form a snug double sleeping bag by zipping to any Ascent, Trek or Traverse sleeping bag
• Shaped for comfort: Narrower at the shoulders, wider between the hips and knees. Regardless of the position you sleep in (figure-four, on your side or on your stomach), this shape provides a significantly higher level of comfort by giving you the room to move without compressing the insulation.
• Warmth from additional insulation: Additional insulation compared to unisex bags, positioned using different body mapping for thermal performance exactly where it is needed. The comfort and versatility-oriented Journey and Altitude sleeping bags have an additional Thermolite layer in the footbox to warm your feet fast. Temperatures for Women’s sleeping bags are shown using the gender appropriate Comfort rating
• Maximum comfort for a good night's rest: Construction details like snug-fitting hoods and oversized draft tubes keep you warm in cooler weather. As temperatures rise, the Free-Flow zipper system of the Journey, Venture and Altitude allow you to increase ventilation up to the point where the bag opens completely flat as a quilt. Super-soft fabrics are comfortable in any season. You don’t have to narrow your options with a constrictive mummy bag – expand your horizons with a sleeping bag which fits the way you sleep.
