Description || Amplitude Down Sleeping Bag


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.

Frequently Asked questions

Warm enough for cool weather camping or travel?

Yes. The quality down and technical construction keeps you warm even on chilly nights. We recommend the Amplitude 5°F paired with a greater than 3.5 R-Value sleeping mat, like the Comfort Plus Insulated. This pairing will keep you warm through shoulder seasons.

Suitable for summer temperatures?

Yes. The full-length side zippers and foot box zipper can be opened for ventilation or remove the upper section completely for use as a comforter.

Fitted with a sleeve to slide in a sleeping mat?

No - instead the lower part of the Amplitude is fully insulated to avoid cold spots – elasticated straps on the underside attach to a sleeping pad of your choice to form a roomy, cozy sleep system.
