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 cozy 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 cozier would be a double version - and we have that, too.

Frequently Asked questions

Is this down sleeping bag warm enough for cool-weather camping or travel?

Yes. The quality down and technical construction of this sleeping bag keeps you warm even on chilly nights. We recommend pairing this bag with sleeping pad that has a higher than 3.5 R-Value, like our Comfort Plus Insulated, for added comfort in cooler temps.

Is this sleeping bag suitable for warm weather and summer temperatures?

Yes, this sleeping bag is great for warm-weather camping. It features full-length side zippers and foot box zipper for ventilation, or you can simply remove the upper section completely to use as a lightweight comforter.

Does this sleeping bag have a sleeve to fit a sleeping pad?

This sleeping bag does not have a designated sleeve for your sleeping pad. Instead, the lower section of this sleeping bag is fully insulated to avoid cold spots and features elastic straps to secure your sleeping pad.
