Is this sleeping mat comfortable at this thickness?
Yes. Thickness isn't the key factor for sleeping mat comfort – the number of points of suspension is. Our air sprung cell sleeping mats support your body weight with hundreds of individually air-filled springs.
Is this sleeping mat easy to inflate?
Yes! The supplied stuff sack features an integrated Airstream Pump which will quickly inflate the sleeping mat. This means no dizziness for you, and practically no condensation moisture inside the mat. Did you know that you can turn the Stuff Sack inside out and have a pump for your Sea to Summit pillow? Try it out!
Does the sleeping mat make noise when I shift around in my sleep?
Air mats (such as our Air Sprung Cell mats) are in general noisier than mats that have a foam construction (such as our Self-Inflating mats) due to their technical construction. However, the reflective material (Exkin Platinum) and the durable outer material of our Air Sprung Cell mats are both very quiet compared to other mats in this category.
