stick to the first option maybe?
I have both and love the litespeed.......
the vapourise I use, but not sure why as its too warm for 3 season often? and too cold without.
is'nt waterproof but I nikwaxed it to improve it...the hood isn't very good for wind OR rain????
the best thing for me is, it is very comfy next to skin...but the rest???
conversly I have two pairs of VR pants that I love for winter or sleeping in/camp wear 3 season use..the inners dry quickly but not the outer particularly??? again super comfy next to skin but not waterproof..so mixed reviews.
I also love my Montane featherweight pants over them or over Rab powerstetch tights...amazing!
