>>2156877I've hammocked on the beach in hawaii in the summer with 70 deg nights and gotten cold from just the wind,
the wind can be just as bad as the cold sometimes, especially if it's raining,
a superlight bag or even a warm weather sleeping bag liner will handle the wind though and like
>>2156879 said sometimes the wind is nice if it's the right kind of wind
for cold: i used a -30F bag, that's negative temp rating, with no underquilt for car camping and pretty much never had a problem down to freezing temps, but that bag was like 3-4 pounds by itself and way too heavy for hiking,
if you try to use a regular sleeping bag, like +40 or +30F, you'll get chilly as soon as it hits 60-50.
all you really need is a thin layer underquilt though,
the eno ember is probably good for 2.5 seasons but it's pretty heavy,
if you can afford it I'd get an Enlightened Equipment Revolt,
it's twice the price of eno for the same 50 deg temp rating and similar synthetic insulation, but 1/2 the weight,
the synthetic underquilt is better than down in my opinion if you will ever deal with humidity or rain
rainfly's are all pretty similar, it just depends on what shape you want, if you want full 4 side wind/rain coverage i'd recommend Hammock Gear Journey, it's a little lighter than the ENO one and cheaper, i think warbonnet has some good ones in a lot of shapes/sizes but I'm not sure on price comparison, and if you are super rich you can buy the ultralight dyneema stuff but that shit is stupid expensive and not at all durable
