guys, I need some experienced advice.
I have been building a winter kit and the last thing I needed to add was a bag/quilt.
I wrestled with the purchase as a decent winter bag for 0 degree is not at all cheap.
I finally settled on a High Sierra Snivler from jacks are better. They rate this quilt at 0-5 degrees in the product description. It just came in and after looking at it I have some serious concerns.
I took it out, let it loft for half and hour and then got out my 3 season WM Alpinelite to lay next to it for comparison. The JRB quilt does loft up to around the 3-3.5 inches it states on the website. The main difference I see is the "feel" of the down when I compress it. I know this sounds odd, but the JRB quilt will compress down with two hands to almost flat with very little resistance, while doing the same with the WM bag, I get substantially more resistance…in other words the down feels thicker so to speak like denser foam if I had to describe it.
This caused me to go back to the web and do some more research. The fill weight of the jrb quilt is listed as 17 oz of 900. By comparison my WM alpenlite is listed at 21 oz for a 20 degree bag.
I searched around on the jrb website and while the product description says 0-5 degree, the comparison table in another section says 10-15 degree. Thats a lot of difference and concerns me about being at all comfortable in this quilt in real 0 conditions.
Just to see if it was quilt vs sleeping bag related I went to Katabatics website and they list their 0 quilt in long as having 24.2 oz of down fill. Their quilt is wider however 52 vs 58 and claimed at 4 inches of loft vs 3.5 claimed for JRB.
I am not upset with JRB at all and this is not what this thread is about, but I am trying (while I can still return it) to get an honest opinion if this is the right quilt for me.
My gut tells me the 0-5 degree rating is optimistic and the 10-15 they list in another section is more accurate….the low fill weight is what is telling me that along with the "compression" As I already have a great 20 degree bag, I dont need a 15 quilt.
Am I over analyzing this, or am I pretty close…BTW I have always been a cold sleeper.
