Sea to Summit Alpine APII Sleeping Bag (Regular)

Our first choice for extreme cold and high altitude conditions where sleeping well can make or break an expedition. Designed for high altitude mountaineering and arctic conditions, the contoured mummy design delivers efficient insulation, while our updated expedition sizing provides space for extra clothing to be worn inside the bag. The anatomically shaped and oversized footbox can comfortably accommodate boots when necessary.

Alpine APII Features

  • Contoured mummy shape for efficient insulation
  • Expedition sizing for extra space and layered clothing
  • Anatomically shaped and oversized footbox can accommodate boots
  • Free-Flow half right-side zip for freedom of movement and additional ventilation
  • Large internal security pocket
  • Includes lightweight Ultra-Sil™ compression bag and storage cell

Free Flow Zip System

The Free-Flow zip design ensures your sleeping bag retains maximum warmth and efficiency when needed and multiple ventilation options when it’s not. The half zip on the right side of the bag (left side on women’s bags) provides freedom of movement for both arms, additional ventilation and also means the top third of the bag can be folded down as a mini quilt when the mercury climbs higher than expected. A separate foot zip on the Ascent, Altitude, Traverse and Venture provides extra ventilation and also transforms the bag into a full quilt.

850+ Loft Ultra Dry Down

850+ Fill Power indicates that 1 oz of down will re-expand to over 850 cubic inches after compression. Higher loft means that less down can be used to achieve the same temperature rating – important for performance sleeping bags. The loft and down quality/composition are independently tested by the International Down and Feather Laboratory (IDFL) – a copy of the certification is supplied with every Sea to Summit sleeping bag.

ULTRA-DRY Down™ is a permanent nano-level water repellent polymer treatment applied to our down which protects it from external moisture and condensation from inside the bag virtually eliminating the negative effects moisture has on down.

EN13537 Rating

The EN13537 is a European standard for sleeping bags that provides three temperature levels to help guide you when choosing a bag.

Comfort - The temperature at which a standard woman can expect to sleep comfortably in a relaxed position. If you are female or consider yourself a cold sleeper, use this rating to decide the coldest temperature the sleeping bag is suitable for. We emphasise the Comfort temperature for our women’s specific sleeping bags.

Lower Limit - The temperature at which a standard man can sleep for eight hours in a curled position without waking. If you consider yourself a warm sleeper, use this rating to decide the coldest temperature the sleeping bag is suitable for. We emphasise the Lower Limit temperature for all our unisex sleeping bags.

Extreme - This is a survival only rating for a standard woman. Between the lower limit and the extreme rating a strong sensation of cold must be expected and there is a risk of health damage due to hypothermia. This is an extreme survival rating only; we do not recommend you rely on this rating for normal use.
