The conversion from mummys to EE quilts has resulted in great gains in comfort and weight-savings for our entire family. We recently bought 20° Revelation Apex Juniors for our two little ones; ages 8 and 10. They love them! Our first backpacking trip of 2017 saw lows just below freezing. The girls stayed warm. Both slept in sleeping layers. The 10 yo slept on a torso-length foam pad and was fine until nature called early in the morning. She got chilled leaving her quilt, so slept the rest of the morning with it fully cinched and wearing her puffy with hood. It worked as planned. The 8 yo slept on a full-length inflatable, using the EE strap system. She didn’t even wear a hat and sawed logs – I was amazed! We are now a happy ultralight backpacking family in large part due to the existence of Enlightened Equipment – what a great company!
