I've been using the Cap 1 and 2 exclusively for years now. I find that a R1 Hoody works better for me, over a Cap1or2.The Cap3&4 have been languishing in my closet for years.
I've never owned the Cap 3 or 4 - why do they sit in your closet? I'm chewing on buying one of each and trying them out for winter hiking - which are much like the temps and terrain of alot of my elk hunting minus the altitude. My thought is a Cap 1 or 2 next to skin, Cap 3/4 over to wear during early AM hikes to my destinations. Arrive then put on whatever clothing the temps call for. I've been doing this for years - its only after I tried thick merino next to my skin (260 wt) that the cold/clammy feeling stayed with me for way too long.
