Our advice would be, check the quilt that you are using. If it is old, or filled with polyester, or too heavy, that is usually the problem.
A natural fibre quilt is essential for cooling you especially in warm climates.
We have a range of summer weight quilts available on this site. Just go to the alpaca quilts product page and select "Summer Collections" on the right hand side bar and the quilt selector will show you what we offer.
Alternatively use the warmth rating selector - either Very Cool or Cool and you will see various alpaca quilt styles to assit you
