Hi all,
Just thought I'd let others know that Mountain Equipment (Kent St, Sydney) is selling the Lowe Alpine Zepton 50 packs for $150, which I reckon is a pretty good deal. In my opinion, they're an excellent lightweight internal-frame pack - I bought one myself. I weighed it at 1164g. They do not have an adjustable torso length (i.e. they will either fit you or not), however there is an XL size as well as the normal size. I believe there is also a women's model. They also received a "Recommended" rating from Roger Caffin in his 2010 State of the Market report for backpackinglight.com.
Cheers,
Chris
