So, after a decade with a 1.6-lb tricked out REI Gore-Tex behemoth of a jacket, I'm ready to replace it with some lightweight and appropriate gear for the types of hiking I do.
I'm not new to backpacking, but am new to giving my gear any real level of scrutiny and research, so would love comments on my proposed plan. Keep in mind that I live in the Northeast but do make it out to the High Sierra at least once a year, and occasionally get to further-flung places like the Andes.
1. Windshirt for trips where cool/cold, windy, non-raining weather is likely (e.g. Sierra trips with lots of above-treeline travel). Maybe also use for my daily bike commute on chilly fall/spring days?
2. DriDucks jacket for on-trail trips in warm/humid weather (Northeastern summer) or where rain will be rare and brief (Sierra summer).
3. More fully featured WP/B jacket for trips with bushwhacking/scrambling, or where significant rainy weather is possible or likely.
So, two questions:
1. Does this list seem right? Is it worth having both a windshirt and DriDucks, or could I use the DriDucks jacket as a windshirt? Is there any redundancy or gaps here, or should I be fully covered for most trips with these layers?
and 2. Given my broke grad student budget, what WP/B layer would best serve my needs? I'm looking at the GoLite Tumalo Trinity because it seems to have the right balance of features and functionality for only $75, and it's available in size S. Are there other options that would be better without breaking the bank?
Thanks for your patience!
