I started short hikes a few years ago with the agreement that I made with my wife that I would either use what I had or keep the cost of what I needed low. I hammock camp and have been using a closed cell foam pad and a mummy bag that claims to be rated for 0-degrees. I was highly skeptical about the claims on the mummy bag but figured it would be alright in the 40-degree weather I usually hike it. Boy was I wrong. For the past two years i have shivered my way through the night any time the temperature got into the 40's even wearing a puffy coat and cap at night.
After the last trip, where the temperatures got into the 30's, I told my wife that I need to take care of my sleep system as it wasn't doing it job. She agreed that I could spend the money to improve my sleep system.
I can only replace one item and am trying to figure out if I should replace the sleeping bag with a quality (comparatively) top quilt or should I replace the foam pad with an under quilt.
I would like to hear some suggestions and opinions so that I make a better decision.
Thank you in advance.
