ha, very interesting. but even if SD makes good on the wp and keeps same weight, for me there is still the question of breathability
I’m going to sweat as a pig anyway, no matter what I wear (running and biking) but a more breathable windshirt (the Ion) should at least minimize discomfort by encouraging evaporation, I hope. Also, I should be able to take it any time I’m out, which is not something I am willing to do w/ my Pac Lite top
any opinions by others more experienced are greatly appreciated
