Warning: There are a huge amount of Arc'teryx fakes on EBAY at this time.  These are clearly fake items not worth $5-20 at best.  If you have any doubt do not buy or make a thorough comparison with Arc'Teryx website for the EXACT item.  Do not rely on Paypal or EBAY to get your money back.  These sellers will disappear before the process even starts.   I have over 20 genuine Arc pieces and it is easy for me to spot these fakes however the sellers will get wise and not include the photos that give up these items as frauds.  If you want to buy genuine "keep your life alive" Arc pay the price or buy from qualified sellers with 100's of feedbacks and a history of selling genuine items.  If you are good and patient you can typically get new Arc items from last year for about 50% of retail.
