AlpinLite

Of all my bags I use the Alpenlite the most. Have used it all over North America from the Arctic to Utah. It’s comfy, light and when needed - warm. I’m roughly the same size as you and it’s plenty big. You don’t need the overfill.

I'm 6'2 and have the 6'6 version of the alpinlight. It's a very warm bag and if I'm in night time temps of 0 - 5 celcius, I just unzip the bag and use it like a blanket over me, and my body temp is kept perfect. I'm a side sleeper and it's a comfy bag to use for that even when zipped up. Ive never felt the need to overfill it. It's the one and only bag I own, and it works good in all conditions!

I'm a 5'9" male and fluctuate between 155-160lbs. I've owned the Megalite and still own the Ultralite. The Megalite is the same dimensions as the Alpinlite. At your stated size, I would definitely recommend the larger size of the Alpinlite. I think you'll appreciate the extra room. I always recommend the over stuff. It really helps to firm everything up so that there is less down shifting, which helps to eliminate cold spots.

Getting an EE quilt that is 20° warmer than your use case comes out to be just as expensive and heavy as going with an absolutely top of the line Western Mountaineering bag. Eg: WM Alpinlite (20°F) = $710 and 880gr. EE Enigma 0°F = $610 and 821g + $70 and ~80g for a torrid hood (and this piece of crap doesn’t even have differential cut or edge tension control, while having double length U-shaped baffles that promote down migration/cold spots and is a straight up cost-cutting design choice).

>I was absolutely freezing all night >Current setup: 20° EE quilt There’s your problem, read more below. Others have said that your pad is the weak point, but at above freezing, it should have been adequate. However, if you are loosing heat to the ground, adding clothing layers really doesn’t help, so despite your seemingly overkill setup, the pad may in fact be the weak link. Otherwise (from a fellow cold sleeper) down pants make a huge difference for boosting the warmth of your sleep system. I know EE quilts work for many people, but ignoring their racism, the design sucks and has several features that compound negatively unless conditions are close to ideal/you are lucky/you are extremely skilled: -extremely long (12+ft) baffles that promote down shift and cold spots. Even if a baffle is perfectly filled there will be some down movement, and the larger the baffle, the larger this cold spot will be. Also, the U-shaped baffles are a straight up cost cutting decision since there are less chambers to fill (the high price does not reflect this). -no differential cut. Differential cut (smaller inner fabric, larger outer fabric) helps maintain the 3D shape of baffles and stabilizes down. No diff cut plus super long baffles equals even worse performance (unless down is perfectly distributed and stays that way). -limit rated. Quilt will sleep colder / be heavier than expected. Granted many makers use limit rating, but the best regarded ones don’t. Limit rating plus no diff cut plus long baffles equals bad performance. FWIW, I have a 20°F EE quilt and a 20°F WM bag. The bag sleeps true to the rating while the quilt looks like a straight up piece of crap next to it. Based on the performance and specs, I estimate I would have to upgrade to a 0°F quilt plus hood to get the same performance as the WM bag, but the quilt will be *heavier*, only $30 cheaper and still have all the bad design choices mentioned above.

Others have already mentioned EEs problematic position regarding racism and fascism, but you also need to keep in mind that their quilt design (even though it might work fine for some) objectively sucks: -super long U-shaped baffles that promote down migration and cold spots -no differential cut (differential cut helps stabilize the shape of the baffles and boosts performance -no edge tension control (elastic around the quilt opening to minimize drafts -limit rated, meaning they are not as warm or light as the appear -expensive considering the above points Note that I have a 20°F EE Enigma and a 20°F WM bag. The WM bag makes the EE quilt look like a straight up piece of crap. I estimate that to get equivalent performance, you would have to go with a 0°F EE quilt plus dedicated head insulation; by that point WM is only like 30$ more expensive, WM is actually lighter, and EE still has a crap design.

If money isn't a factor, then I'd recommend a bag from Western Mountaineering. I've had their Alpinlite bag for a few years and I love it.

My Western Mountaineering Alpinlite bag. It's roomy, warm, and light in my pack. I once did a trip in Arkansas when I was still somewhat new to backpacking and didn't understand sleeping bag comfort ratings. Temps at night got down to low 20s and I had a 20 degree so I thought I'd be good. Froze my damn ass off every night and was miserable. I swore I'd never make that mistake again and splurged on a nice bag when I got home.
