There was some discussion about the recent COTD: https://www.ozbargain.com.au/node/176733
Though a better price, that luggage was a hefty 3.63kg (described by marketing: super lightweight).
Credit to Logical for pointing this deal out there, and for johninmelb giving some background: "but it was 40% off RRP, and was the cheapest I have seen it in the time I have been looking for this specific bag."
Note: the $64 is only for blue and red. The black appears to be $89.10.
Beware, I had one of these but it fell apart after only 2 trips! (Both to the US for 7 days).
Yeah it sure is light, but it comes at a cost!
