Backpacking in the tropics

I'll hike the Z trail every few years in Hawaii, which is hot during the day, about 60 at night. I did not need that much clothing, equipment, or (last time) even hot food. Used a set of rock craft pants that stay rolled as shorts to unroll in the evening. Brought a 45F phantom bag just in case but will like leave it for a bag liner next time. Probably have a Cuben-fiber shelter too.

Needed more water tho.

In french Polynesia, it got down a little below 80 at night. Day times in the mid 80's but it got pretty humid. I read a report where some people backpacked there for a month or so.

I grew up in the desert so I'm not used to any kind of humidity whatsoever. I was stationed in Panama and I never got over how muggy it is; I'd sweat like a pig all day. It seems like you have to grow up in that climate to tolerate it well.

Lows in the 80's is a little much for me. Like wearing cotton in the desert though, it might mean that instead of using a sleeping pad with some sort of R rating for insulation, a camper would go for a regular air mattress to conduct heat away or a hammock to maximize air flow.

Just some thoughts.

You can improve things a little, but humid backpacking is mostly miserable. When its humid, nights tend to stay warm and muggy. That why most of us in the SE US will only hike at high elevations in summer.
