AERO handled this QC issue respectfully - see post #34 On the back side of the sleeve where it attaches about 3" from pit i found 4 broken stitches. Its pretty minor... but i guess could be problem down road. Im sure they would repair it free of charge if i were to send back... but then i probably would be charged shipping? Should i send back for repair? This is on the 50s halfbelt i decided to keep... and overall think the jacket is great.
