Always warm clean socks when it's chilly. a knit hat if it's very cold. a fleece sleeping bag liner if it's near freezing. makes a big difference. and sleeping pad makes a big difference too in cold weather. an insulated pad or the ground will keep you much warmer than a non-insulated, air filled pad that increases the ability of heat to leave from all directions. |

I was told this method keeps your body heat, which would be radiating off your skin, in the bag, which is crucial for helping it keep you warm. Apparently the theory is that with clothes on, that heat won't fill the bag...or something. I've tried to google an answer for this and look at recommendations from sleeping bag manufacturers, but haven't really found a good answer. Now that I've typed this question out, it sounds rather silly and like an obvious piece of 'fake news' that made its way into my orbit at some point. But, anyone got an answer? Winter and shoulder season campers may have some good input here. |

As for wearing too much clothing, if you do, it's possible that you will compress the insulation in the bag. If it's compressed too much, resulting in a loss of loft, it will be difficult to stay warm during the night. There's only so much room in a sleeping bag so if you force too much in that space, something's going to give; and it will probably be a compression of the insulation. That's all for now. Take care and until next time...be well. snapper |

"The Euro ratings are based on a sleeper wearing one synthetic baselayer (top and bottom) and a hat, and using a closed-cell foam sleeping pad." It doesn't make sense to me - I don't put more clothes on to sleep cooler in my sleeping bag in the summer. |

I know how much down above me is needed to keep warm in a t-shirt and shorts. After that adding a base layer to increase cool performance as needed is what I do, it can be overdone and the base should not be restrictive or tight at all. If 1 layer does not work add a hat then gloves. Along with and in the same stuff sack as the S bag, I carry a medium weight set of merino wool long-johns and a balaclava, to add or not as conditions warrant. The key is circulation, do not impede it at all, nor so compress the bag insulation from the inside. For me 2 1/2 to 3 inches of loft in a baffled cover, works for 3 season use. 4 inches will get me to 0 degrees. Also an insulated pad needs to be used with a R value suitable. I use a R 8 winter, R4 for 3 season. Yes treehorn, you can over layer in a sleeping bag. butthead |

boonie: "It still doesn't make sense to me - if the sleeping bag doesn't capture and hold the heat when you're wearing a base layer, isn't that because the base layer is doing so? If I'm not in a sleeping bag, but wearing clothes I don't take off my baselayer to be warmer when I put on a down jacket . . . ?" It's a finer balance with freedom of motion when active vs a volume constrained sleeping bagand sleeping. Extra layers added when sleeping quickly start to compress skin surface blood flow. I have noticed adding another layer on top of my merino woolies will cause chill after a bit when snuggled inside a bag. If the woolies are not warm enough on goes the balaclava after that point I may add a coat over the outside of the bag but no extra inside. Also physical size and interior sleeping bag volume alter the comfortable temp range. Insulation only works when uncompressed, and it is easy to max out the volume inside a sleeping bag butthead |

How do I know this? I've done it many times over the years winter/early spring/fall camping. For example I was camping in December last year with a light base layer top, mid-weight layer bottom, socks and a balaclava. When I sleep I tend to ignore getting cold for a very long time before I do something about it. After tossing and turning for an hour I realized I was just not warm enough. The light base layer just wasn't enough so I put on a heavy weight fleece jacket. Lo and behold I got quite warm and toasty and slept comfortable. Yes, compressing the insulation you are wearing/sleeping in will cause your clothing and the bag to lose some of it's ability to keep you warm. So will restricting your body's blood flow as Butthead mentioned. You do have to make sure you aren't wearing restrictive clothing. White Wolf, I believe you because weird shit happens all the time when it comes to winter camping. But I believe I have an answer for you and that is you were restricting your blood flow. And/or what I will call the chimney effect came into play in that by removing one layer of clothing you allowed more heat from your body to better heat the rest of your sleeping bag and hence your body. It's why I bring and wear bibs when I winter camp. I find the heat from my legs helps keep my stomach and chest warmer or vice versa. Take your pick. Happy camping everyone. Stay warm and dry. :-) |

I wear a pair of silk underwear. Extremely light and packaable. I wear them for sleeping and only sleeping. If it's cold I add layers, seems obvious enough. Do not use your sleeping clothes for other duties, like getting up in the morning and cooking in them. |

paddler1953: "One reason to wear something in your sleeping bag is to keep your body oils & perspiration out of the bag and the insulating material it uses. I was always taught that a clean bag is a "warm" bag. For myself, I'm a warm sleeper so in the summer months I typically sleep w/o a t-shirt; wearing just a pair of boxers. When I do, I take the opportunity each day to turn my bag inside out and air it out during the afternoon. This allows any moisture I emitted into the bag overnight to dry, resulting in a higher loft for my insulation and a warmer night ahead. You compress the insulation any way due to your body weight. That is why you need a sleeping pad that is insulated in cold weather. |

mastertangler: "You definitely want dedicated sleeping clothes. It will keep your bag clean. On this occasion I agree with MT. My only for sleeping clothes are not silk, but maybe should be. Flannel pajamas and a heavy long sleeve T shirt. Year round. Never cold. I avoid hot nights outside but usually if caught just sleep on top of bag. And day clothes don't stay in tent in serious bear country (which BWCA is not imho), same as Philmont says. And I try to hang day stuff to air dry if possible, so it's bone dry. I'm always amazed how warm I feel changing into day clothes on a -15 morning, because it's all very dry. Plus who wants all that dirt and grime from day travel in their sleeping bag. Yick. |

I try to not wear anything other than my "sleeping clothes" which vary with the season. Occasionally in the winter I will layer up for sleeping, but will keep the discussion here in mind and try to adopt the "less is more" mindset for the winter especially when there's a backout plan-B nearby. |

That's just my personal system. I don't necessarily believe that this is the best way for everyone. |

f you are in an emergency situation where you are needing to warm up yourself, your bag quickly and perhaps warm up another person, then getting rid of the layers that would trap heat is a very good idea. The bag will generally be more efficient at capturing heat than the closer base layer, disperse the heat more broadly and more quickly that way, thus warming up the inhabitant(s) faster. In that scenario, your base layer would slow the overall warming effect of the sleeping bag and you wouldn't reap the benefit of the sleeping bag plus base layer until a later point in time, which, in theory could be too late, especially if the base layer is wet or cold at the beginning. However, if you are talking about being warm after 6+ hours in cold temperatures, then a base layer should be worn and/or added after your sleeping bag is warm (or if you aren't in a survival situation, you can right away). The more layers, trapped air, and insulation you have between you and the cold air will result in longer term warmth retention. |

On a solo trip on the Island River one time I set up my tent at the Kawish campground and then went into town to fish with a buddy who is a guide up there. At the end of fishing it started to rain, we were partying a tad and I went back to my camp and sat in my truck and listened to WELY and dozed off while the rain pelted down. I woke up and decided it might be a good idea to get truly horizontal so I ambled over to my tent and crawled inside. Did I mention my tent leaks? Taj3, piece of crap tent. Everything was soaked. I had puddles. I slept in my boots and full rainsuit for two nights and some of the day because the next day it rained all day when I went in. And I set up in the rain again, with all wet stuff. With a tent that leaks. I use a tarp as a rainfly now. I guess the moral of my story is you do what you gotta do. I'm not that high tech. If I'm cold, I put on stuff till I'm warm. And sometimes sleep in my rain suit and boots. I might try to get a new tent that doesn't leak and doesn't feel like you could solve Rubik's cube faster than it takes to set it up everytime. Cheers. |
