Sea to Summit Amplitude Down Sleeping Bags are extremely spacious and feature multiple zippers for versatility.

Ideal for adventures with a base camp, the Amplitude down sleeping bag brings spacious luxury and incredibly versatile ventilation options to wherever your travels may take you. Each side of the Amplitude has a full-length side zipper; a third zipper can be found in the foot box.

High-lofting down and quality construction keeps you cosy when it's cold, and the zippers provide temperature regulation up to the point where you remove the upper section and sleep under it as a quilt.

The only thing which might be cosier would be a double version - and we have that, too.

Features:

• ULTRA-DRY Down 750+ Loft 90% Down Cluster Premium Duck Down certified Responsible Down Standard (RDS)
• Vertical baffles over the chest to prevent down shift as you roll over in your sleep
• Full-length YKK® #5 main side zips and foot box zip provide unmatched ventilation and allow the top section to be removed and used as a comforter
• Shaped hood and zipper draft tubes keep cold out and warmth in
• All versions, except the double, include an internal zipper pocket
• Includes lightweight Ultra-Sil compression bag
• Form a snug sleeping bag for two by zipping to another Amplitude or Ascent, Trek, Traverse, Altitude, Journey or Venture sleeping bag
