Doing Mammoth Lakes on JMT south to Piute pass trail ending at North Lake the week after labour day weekend.. First Sierra trip.. Was thinking of not bringing a rain jacket, bring Patagonia Houdini, and a $1 Walmart/Kmart rain poncho. I have a 13 or so ounce Marmot rainjacket I would like to avoid bringing. My insulation layer is a synthetic BMW Cocoon..If rain jacket needed probably would bring a driducks, about 6 ounces..
Also, with trail runners are gaiters needed? Have never used them in the east. Am looking at the Dirty Girl Gaiters, though the adhesive or glueing them to back of my shoes not overly appealing..Thank you for any feedback!Mike
