1. Really informative about sleep systems,One of the best videos i have seen darwin …including how r values and loft works is information i needed to make a informed decision in my sleep system… keep making videos for us !!! a fan gary

  2. my biggest issue with quilts is that I'm a foam pad guy, and while the bottom of the sleeping bag might not insulate you thermally, it is way more comfortable than laying on the pad.

  3. People are missing the point.
    1. Quilts cost less compared to the same mummy temp rating.
    2. Are way lighter.
    3. More versatile in that most mummy bags have a 60/40 or 70/30 ratio of down on top to down underneath. So it's much colder on one side when it's unzipped and draped over you.
    Etc etc

  4. Way before I heard of camping quilts, I used a 0C (32F, comfort) bag as my most used and or a long time only bag. When I'm inside I run the bottom zip up for a little ventilation, if its a little hot, stick one or both legs out via that gap. Sometimes I use the bag all opened up like a quilt. sometimes feet stay the box. Nowadays, with a bag, I'll throw in a real silk liner (v light weight) to boost temp for cold nights, on its own as a warm night bag, or just to crash out someone's bed and you don't have sheets.
    From what I gather, some down sleeping bag designs have less material on the back, as it'd be compressed (for back sleepers) and thus not working, as you say. So for me one of these wouldn't work. Especially as Im mostly a side sleeper. My bag is a good synthetic and great warmth to weight, evenly distributed all around. So as not found a terrible need, quilts… its still in the untried shelf.

  5. I am mostly concerned about a down quilt getting wet. On the Appalachian, how much of a problem is this going to be if any? If the quilt is high quality and new will it dry well? Will the down stay dry in a huge rainstorm?

  6. I know this is an older video, so hoping you can still answer a question. I am a bigger guy and always sleep on my side or front ( I actually find the recovery position very comfortable) mummy bags tend to be for back sleepers and I just can’t sleep that way. I’m considering a quilt and even considered things like the selk bag, but they’re just too bulky.
    Do you think a quilt would be more suitable for a front/side sleeper?

  7. Zipper won't fail on a quilt. Had 2 zippers fail on mummys. I am a stomach sleeper and always unzip to use as a quilt anyhow, but they don't set right because the hood is off center–looking, at the sierra because of integated hand pockets and stargazing hole. The backcountry bed looks like a great in between too.

  8. I know you're trying to sell stuff for sponsors but…..

    1.) Unzip your sleeping bag all the way and throw it over you…..voila, quilt.

    2.) You can stick your feet out of a quilt? Really? What sleeping bag does not zip from the top and bottom specifically so you can hang one or both legs out to vent excess heat?

    3.) Many quilts have adopted a foot box…..just like a sleeping bag.

    On the flip side…..you will never get a quilt to seal up like a sleeping bag for maximum conservation of body heat. Including your head and face. Quilts also leak heat every time you move.

    Sorry, the whole quilt thing is just dumb. You're not saving much weight and you're potentially sacrificing a lot of comfort as well as a good night's sleep.

  9. My down -4’C mummy sleeping bag has a side zip and a foot zip so it can become a quilt when needed. I also use the Sea to Summit reactor liner 18’C and the two of them kept me cozy in Namche, Nepal during winter.

  10. The entirety of the mummy bag is not being completely compressed, there is plenty underneath the body that is lofted, combined with the pad, adds a higher R-value than a quilt on top and only a pad underneath. Add a roll of refectix underneath the tent and it's the warmest floor I've slept in.

  11. why not just keep your original bag and add a blanket, when its too hot just sleep on top of the bag and cover with the blanket, when its too cold add the blanket inside the bag, and vice versa.

  12. If the insulation on the back (bottom) of the sleeping bag is useless, then why dont sleeping bag manufacturers remove it and just leave a piece of enpty material with the insulation blocked so it is only on the top and sides?

    Like a quilt, but with material holding each side on the bottom instead of straps.

    It sounds like common sense, they can reduce the weight and the materials used, therefore making a lighter, cheaper bag that they can sell at a premium for being "ultralight".

    Is there a good reason why they dont do this?

  13. I totally agree. I hold fast to the mummy bag for winter camping excursions where I know for a fact I want to trap all heat possible. For longer hikes or when travelling to a trail where I can't be certain of the weather I like a medium r-value ground pad on a small tarp, a rather heavy wool blanket (lotta work keeping that dry, but amazing r-value) and a down quilt. I can use the wool blanket to bolster base pad r-value, tuck the quilt around me to get the mummy bag effect, or I can roll up in the wool blanket and again tuck the quilt around me. If I arrive at the trail head and weather is mild, I can leave the wool blanket behind to save on weight. The weight of wool sucks, and finding creative ways to keep it dry is a challenge, but as an in between layer it adds soooo much more warmth. I really do like being able to stick a leg out in the cold if I am overheating when sleeping so bags suck unless I know for sure I won't be overheating.

  14. If choosing to use a quilt what style/shape of pad is necessary? Obviously an insulated one but should it be a rectangle pad or can a shaped and lightweight one work? Thicker like a 3-4" pad? I checked out the Enlightened Equipment page and it seems their quilts are almost like sleeping bags anyway; the sides pull under you and enclose the body except for about 3 or 4" of area from mid thigh to head. Amounts to a few ounces at best. If too warm in the bag just unzip it. Not hating quilts just curious. Do you need a blanket or something on the pad so you're not laying on pad material to sleep?

  15. I have a synthetic mummy bag, but it unzips at the feet. (On cold mornings I could put on slip on crocs and sit around all bundled up but can still walk a bit to watch the sunrise.). There are many ways to stay warmer without getting a different bag. Wear a beanie since you lose heat through your head. Depending on the weather and temperature, wear long johns to bed, sometimes I just wore the top since I was hiking with a bunch of guys. Carry a bag liner which adds 8-10 degrees of warmth depending on the material. Wear some fleece socks just for sleeping. (long johns and socks are ONLY for sleeping in. Don't hike in them or they will get sweaty and damp and you will freeze at night). Just like in clothing, it's all about layers.

    We started out in August over 100 degrees at sea level. One morning we woke it was 31 degrees. Oh yeah, we were NOT using tents. Sleeping in a tent adds another 20 degrees of warmth.

    So between tent, no tent, unzipping bag in middle of warm nights to get air to my bare legs and or feet if too warm, adding long johns on cooler nights, adding socks and beanie when even cooler, scarf around neck or even a balaclava so the only thing showing was my eyes. Bag liner I didn't need. The top of Mt. Whitney was freezing and windy. Brrrr. In August!! But it was covered in snow still in July that year (2009). I don't use air mattresses. None of the guys could understand how I could sleep on my 1/4 inch closed cell foam (8 oz) pad, but it traps heat, and I don't have to heat up the air in the air mattress. Those suck heat from your body, which might be what you want.

    Something you did not mention is that a synthetic bag will keep you warm "enough" even when WET, and a down bag is useless. Why don't you bring a cheap emergency blanket for inside on cold days? So many things you can do besides a whole new bag.

    My bag is a Cat's Meow from REI, mens size since I am tall and have no hips. Not sure if they are still sold.

  16. I have used a mummy bag one more way than you mentioned; fully unzipped and upside down on me like a duvet.

    There is a cheaper duvet than down. Use 2 inch quilt batting/insulation, it is called a Rayway duvet.
    It is homemade. The quickest way is to get a double bed sized shiny polyester bed topper that has 14 inch frills on three sides. Add the batting and a polyester lining and make a waterproof bag.
    You tuck the frills under your body. You still need a thermarest mattress. And a beanie hat.
    It is also very lightweight.

  17. I'm glad that set up works for you. But for me, I have to have the mummy bags. I move a lot when I sleep, and a quilt is always falling off or opening up and letting out the heat. A mummy bag is the only thing I found that keeps me warm. When the temp warms up, then I can open the zipper and use it like a quilt on top (with a built in footie), or when the temp really warms up, I use it for a second ground cover.

    Travel light, freeze at night.
