I'm looking to do a superlight backpacking trip. I don't want no bike bags or other bs hanging off my bike. Everything has to fit my 35l evoc. This is why I won't be using a tent and I've been told to use a hammock but I have no real idea about them. Anyone have used them in the summer? Do you need a mat or underquilt during the summer when even at night it's min 60F? Is there anything to look out for or avoid?
