I have both the Nunatak ArcUL -7C(20F) and the EE Revelation -7C (20F) quilts. The EE quilt is definitely not as warm as the Nunatak- about 5C -6C difference I would say. I would now, after much use, not take the EE to more than 0C and I now would use the Nunatak for everything to the quoted -7C. If in doubt I would take the Nunatak. In coldish weather I sleep in thermals, socks and woollen beanie. The two quilts warmth is not the same. I believe EE has looked into this. I don’t blame EE for this as an EN rating I believe is impossible to attain for a quilt and I am used to the idea of LIMIT and COMFORT ratings as per the EN standard for sleeping bags. For me the “COMFORT” on the EE is about 0C and the Nunatak is well towards/close to -7C. I bought the Nunatak 6 months ago and the EE one year ago. Also the Nunatak exactly matches the promised width dimensions, the EE does not by several centimetres.
More and more backpackers are switching from sleeping bags to backpacking quilts because they’re lighter weight, more compressible, and more comfortable, especially for side sleepers. While top quilts have always been popular with the hammock crowd because they’re easier to use in the confined space of a hammock, they’re also a great sleeping system option for ground sleepers, when coupled with a sleeping pad. Backpacking quilts are ideal for summer and warm weather since they’re so easy to vent if you’re too hot. But in freezing temperatures, starting at 30 degrees and below, most backpackers still prefer a sleeping bag because the wraparound fabric is less drafty.
I don’t own a zero rated sleeping bag anymore. Instead, I have a 20 degree bag and a 20 degree quilt. Typically I use the quilt for most camping and then when it gets too cool (typically in the under 40 range) due to me moving and causing drafts, I’ll switch to the bag. Then, when it’s even colder (I’ve been down to near zero) I simply use the quilt over the sleeping bag and I’ve been plenty warm – even more so than my old 0 degree. The bulk isn’t much more than what a real 0 degree bag would be. Things like my phone can be placed in the zippered pocket on the outside of my sleeping bag and kept warm enough by the quilt.
FEATURES: Most ultralight backpacking quilts are pretty similar when it comes right down to it. But there’s something unique about each of manufacturer’s quilts listed above that improves their performance in a unique way. For example: the use of continuous or chevron-shaped baffles, draft collars, zoned insulation, closed foot-boxes and external snaps for quilt layering, all improve cold weather performance. A strapless pad attachment system is far more convenient and comfortable than ones that rely on straps, while a head-hole enables multi-use as a garment. Look for these differentiators because they can have a profound influence on your backpacking experience.
The Loco Libre Gear Ghost Pepper is a down quilt made with a unique chevron style baffle, which limits the amount of down shift by catching it in the corners that the baffle forms every time it changes direction. This eliminates cold spots and means that the down stays on top, where you want it, so you can stay warm. The Ghost Pepper is available in a wide range or widths and lengths, color choices, insulation types, and foot box styles. You can even add a sleeping pad attachment system. This can all be very confusing for first time quilt buyers, but they are very patient and happy to explain “the why” before you buy. Some of the of the key options offered are 800 duck or 900 goose fill power water-resistant down, a draft collar, different taper styles, a drawstring vented or closed footbox, and added insulation. A basic Ghost Pepper 40 weighs in at 14.5 oz. Price Range: $154.00-$474.00
The Sea to Summit Ember EB III quilt is very light (it weighs merely 757 grams) and thus perfect for those who prefer lightweight hiking. Despite its low weight, it offers great insulation – it has the lower limit rating of -10°C by the EN standard. The shell and lining are made of 15-denier nylon which provides great durability for the weight. The quilt uses 750-fill power Ultra Dry Down which is treated with DWR (Durable Water Repellant) so that it resists moisture. Sea to Summit claims that Ultra Dry Down absorbs 30% less moisture than untreated down and is up to 60% better at retaining loft when wet. The Sea to Summit Ember EB III quilt also features a footbox with a drawcord and an adjustable strap system for easy attachment to the sleeping pad. Press studs down the side of the quilt allow you to close the lower half for better insulation. The Sea to Summit Ember EB III quilt is due to its low weight and superb insulation a great option for hikers, mountaineers and other outdoor enthusiasts who need reliable sleeping equipment for 3-season hiking.
If you live in a place with a real change in seasons, look for a midweight quilt that will be comfortable when it’s warm out, but that’s easy to layer in the colder months. Choose a quilt in a solid, neutral color to give yourself the most flexibility as you transition through the seasons: In summer, pair it with lightweight cotton or linen sheets, then in winter trade in flannel sheets and top it with an extra throw blanket or duvet if you need more warmth.
