Whilst trying to think out how to deal with rain and how to improve my tent sleeping arrangements I decided on buying two very cheap items.
I bought two pairs of black tights recently which grip around the top of my thighs but have no feet to them, they just secure around my ankles, they are just lightweight leggings, light as a feather and they came all the way from China, I paid just over £5 for them. I wanted them for two reasons, firstly to keep my legs warmish, I don't like to wear john johns as I tend to get too hot in them. The second reason and I don't know if anyone else experiences this small problem, is when I have been hiking all day and even after a shower my legs can feel hot against each other in the night. I wore them recently and the material works, it separates one leg from the other nicely and I never experienced the hot skin problem at all.
My second item was from Amazon. I just typed in Rain Skirt and bought a new one for £10. So lightweight and fits into a tiny little bag as well.
