Frequently Asked questions

Can two Spark Pros be zipped together?

The Spark Pro is only available with a left zip, but can be zipped to other STS Women's sleeping bags

Is the Spark Pro available as a women's model?

We don't currently offer a women's-specific Spark Pro. The unisex model works for female end-users (who should use the Comfort rating for orientation)

What's the difference between the Spark and the Spark Pro?

The Spark Pro has a footbox zipper and a short right-side zipper (great ventilation, open-flat as a quilt, sit up with arms extended from the bag)
