I have noticed a few sleeping bag manufactures making them with ways to attach or hold on to sleeping pads on the exterior of the bag. Would there be any advantage to placing your pad inside you sleeping bag since the bottom of your bag is relatively useless being compacted with your body weight?
The main advantages of placing in your bag is to keep from rolling off and to take up volume. Too much wiggle room inside of your bag and you will be pumping warm air out all night while you pump cold air in as you move.
I usually put my pad on top of a cot. Sometimes i put the pad in my bag so it doesn't move around. I haven't noticed any additional warmth inside the bag vs outside, but I am sure others will have more informed input than me.
Spot on. The only time it would be waker is if the bag is really big for you.
I used a closed cell ensolite pad with a ground cloth of some kind. It also helped in the back of the Scout or on a cot for insulation. Not meant for comfort but could always make a hip hole in sand, snow, or dirt with leaves.
Hip holes are a good idea in non sensitive areas. They work really well, thanks for the reminder Jack.
One thing that was missed and is worth mentioning is weight capacity. The air pads will be able to fat guys like myself off the ground more easily. I use a Exped Downmat XL and it keeps me off the ground. The filled air pads typically have the highest R-value of all the pads. I have also noticed my Downmat is much more durable than I expected. The life of the Downmat will be atleast 20 years. I have owned two for about 10 years and they are still going strong. I do still use 3" open cell pads from Smith's Market Place but I need about 6" of padding to keep my 300lb fat but off the ground. Over the past 30 years of using open cell pads I have noticed they are pretty worthless after 6-7 years.
good point. Those down mats are really nice pads.
I've been using the same open cell pad for more than ten years now. Still going strong - used it on some below zero nights last weekend.
I almost always use it on a cot though. And I use the relatively cheap cots. They typically only last me about three years.
