Sea to Summit Cinder Cd2 Down Quilt

G'day Mark,

The difference in price is largely due to the quality of the down between quilts & the amount that has to be used to achieve the same insulation.  The Eb2 has a higher grade down which lofts better, and therefore insulates better, gram for gram.
Realistically quilts are not able to be EN tested for a proper warmth rating like a sleeping bag, so the comfort ratings are chosen based on the performance of sleeping bags with the same or similar grade & weight down.

The higher the R-Value of the mat, the more the mat will insulate you from losing body heat through the ground.  If you are concerned about sleeping cold, the higher the R-Value of your sleeping mat, the better.  There's a whole range of other factors to consider, including your physical body composition, the ambient temps, how much you've eaten, how much physical activity you've done during the day.

We'd recommend listening to our podcast on Sleep Systems with Sea to Summit to get more info on how to sleep warm & get the most out of your gear.

G'day Mark,

There's no real difference in liner selection between a quilt and a sleeping bag.  You'd just choose one based on your requirements & personal preference for materials and comfort.
The primary purpose of a liner is to protect your quilt or sleeping bag from needing to be frequently washed, if your requirements are additional warmth, you'd just choose one with greater thermal properties.

G'day Wayne,

The Cinder 1 quilt is stitched through, whereas this Cinder 2 has boxed baffles.
Hope that helps!

G'day Nick,

Sea to Summit have advised that whilst these are better suited to the tapered mats, they will still work with the rectangular mats.
Hope that helps!
