Montbell's Alpine Down Hugger 800 Thermal Sheet is a lightweight option for summer camping. It works as a hoodless sleeping bag and can be fully unzipped to act as a quilt depending on what you want from it. Weighing just 386g it uses 130g of 800 Fill Power Down to get a 10°C Comfort Limit which is great for warm weather camping. However, due to it's size and the versatile design you can certainly get more use out of it as a way to boost the temperature rating of your current sleep system.

This Thermal Sheet uses some seriously advanced technology unique to Montbell in the Spiral Stretch System which is contained in the diagonal baffles. This does a great job of keeping the down in place and eliminating cold spots. There is also a draw cord at the neck to help keep the warmth in whether you're using it as a bag or quilt.
