Gear

the filament has a semi-automatic front zip with anti-snag baffle, rollaway, foam peaked, lined hood with concealed single hand adjustable face aperture draw-cords, two, map sized, zipped chest pockets and single hand operated, elasticated draw-cord hem.

absolutely nothing like a featherlite smock apart from they're made from pertex.

WTF is "a semi-automatic front zip"? 

Do Crux use them on the AK47?

the kinetic is a slim fit stretchy top (i have two of them). it is unlikely for a pertex windtop to be that close cut.

i know a montane medium fits me just fine (except the extreme jacket/smock). the litespeed and featherlite are more or less the same size on me.

if a wind top is a bit flappy it doesn't bother me. it matches all the other loose, wobbly bits.
