Acetone or nail varnish remover dissolves the tars. It's possible that kerosine or gasoline could work but acetone worked.

I find that simply tying a half knot below the buckle keeps it from slipping:

200 liters of air weighs about 240 grams and heats up about as fast as 240 grams of sleeping bag, or 240 grams of yoga mat, I mean in a short time. It was reported that the air never heated up much though. Well that was because the air was moving around and dumping heat into the ground, as still air is one of the best insulators. If a bony person lays ...

Your friend isn't thinking clearly. Imagine they had asked the question: On a cold night, is sleeping naked and unprotected better than sleeping in a sleeping bag? Everyone intuitively knows that you will be far warmer inside a nice, lofted sleeping bag. The insulation retains your body-heat and prevents the cold air outside from reaching your skin to ...

Happened to see this and had to register just to reply because I have first hand info. I was fixing up an old mobile home and had removed the skirting and slept on a air mattress in a room with a wood stove. I thought it would be ok but since the floor was the outside temp the air mattress became ice cold. The air in the air mattress just gets colder and ...

I use the Manfrotto Offroad 30L pack. This does have a very good adjustable & comfortable fit and works well when you have a loaded harness. It is not too bulky and I rarely need all the space even with overnight bivy and all inside. The camera gear stays at the bottom in it's own are, (only room for camear plus 2 lenses so Canon 80D 12-28 f4 & 70-...

If you've got the strap to the perfect length and want to maintain that length, you can sew a small fold in the strap, similar to what's used at the end to stop the whole strap running through. Slitting the stitches means you can change your mind later. Realistically this won't help for a waist belt that needs to adjust to different clothing, except as a ...

Some more factors here: 1) Even if the air in the air mattress was the same temperature as the outside air it has much less thermal capacity and thus will take your heat away slower. 2) An air mattress will spread the pressure more evenly--your sleeping bag won't be as compressed at pressure points and thus heat will escape from them slower.

The solution on my backpack/bike helmet is a rubber band/hair tie like cord around the straps just below the buckle. In order to readjust the buckle you have to loosen the elastic cord around the straps and pull it away from the buckle. Not sure exactly why this works, but I haven't had any problems with my helmet coming loose or backpack straps loosening ...

Effectively, it isn't much better to sleep on an air mattress that isn't specifically made to insulate from the ground than on the ground itself although it does make a slight difference. The main takeaway is that you should always avoid sleeping directly on the ground so even a poorly insulated air mattress will be better than nothing. Your friend isn't ...

There is an old adage One blanket underneath is worth two on top. but I can find little support for this idea except a mention on mumsnet. The reasoning is, that the floor or the ground underneath is solid, and has a much higher thermal capacity than the air above, and so will draw a lot of heat away from your body. It's not just the temperature of the ...

I had the same question earlier this year and found similar resources as already mentioned by others. The table on the UIAA site seems quite complete, however I personally found two issues with the table: It is limited to climbing only while most people who climb are interested in a broader range of safety relevant products (climbing, summer/winter ...
