Richard Nisely presented in 2007 a tread labeled “The best clothing combinations for backpacking or hiking?” (https://backpackinglight.com/forums/topic/9378/#comments). He present a model/chart for optimal clothing combination for most backpacking or hiking. A question I have that needs answering concerning this model/chart is as follows:
Is a Polarguard Delta Micropuff vest is equivalent to Patagonia Men’s Nano Puff® Vest ?
If NOT, what are the differences?
