“The large mummy shape was perfect for shoulder and arm width. Comfortable and good for side sleeping when not fully inflated. Slightly noisy. When a Sea to Summit inflatable pillow is added to the four "Velcro" strips on the mat it stays there and provides an extra comfortable night's sleep. The valve system is excellent. Deflation and pack up is easy. It is good having the pump sack attached to the stuff bag but inflation takes mot goes than with other bags. It still does the job though. Not perfect but certainly recommended.”
