The Commando (2018) was our first product and received almost universal 5-star reviews but #betterneverstops. Based on your excellent feedback, we have tweaked the Commando (previously called Commando V2) to be even better.
Removed the front inner leg seam, a high-risk chafing area
Reverse merrow stitch for a "barely there" seam feel
Tapered leg and more elastic leg hem to stay put
Waistband seam moved off-center back to prevent coccyx rub
Adjusted the sizing for a truer fit 
 
"Helps to combat chafing, incredibly light, very breathable and comfortable and ideal for all conditions." - Ultra168.

The Commando has been extensively tested in Hong Kong's tropical conditions and is guaranteed chafe-free. Please note we use Asian sizing, which can be up to half a size smaller than western sizing.
