I'm less versed on the G1 than I am on the A2 (and that's not saying too much), but can someone help explain the basic diffence in the knits used on these jackets. The reason I ask is because I was under the impression that the G1 knits were a slightly longer in general and possibly a little snugger fitting around the cuff (for less tunnelling) than the basic A2 cuffs. If that's the case, I was thinking this might be an option for getting more length out of a jacket with shorter sleeves (and body for that matter).
