I won’t be brining much in the way of clothes (considering the heat index will be above 100F nearly everyday) but I was able to get my hands on the Sierra Designs Microlight rain jacket and pants. The weight and packability of these two items is key.
I figure rainwear might come in handy in the Amazon Basin even in the “dry” season (which of course is far from dry). The Microlight is polyester taffeta and weighs just a few grams. Although basic enough for use under nearly any travel excursion I am going to put this sucker to the test for sure! Hopefully it doesn’t come back like cheese cloth from mosquito punctures.
