I love my topquilt and underquilt from cedar ridge. I tried my underquilt on my XLC and dutchware chameleon wide. Both no problem. Sleep warm. Both UQ and TQ are rated at 20. Tested down to 17F this winter. Warm with no problem. I used the topquilt in my Draumr 3.0 with winter mat and down to 23f no issues. I have many Hammock gear quilts and love them but wanted a synthetic option for wet areas. Both my cedar ridge quilts at “UP” quilts.
