General comments: Quite why this daysac is in the weekend packs category when the larger Amp 35 is in the daypack category is a bit of a mystery, but never mind.
First things first, if you are after an ultralight mountain marathon rucsac, the are far lighter and cheaper alternatives available (the OMM bags seem to be market leaders - understandably). If, however, you're after a relatively light weight sac for adventure racing, lightweight classical alpinism (where the sac won't be in contact with abrasive surfaces very often), or even hillwalking then this could fit the bill.
The weight on this sac has been shaved off through a bit of thought as much as through the materials used. I perhaps haven't been as ruthless with the scissors as i could have been - partly down to the initial cost of the sac, but equally because very little can be considered extraneous or of little use.
All pockets can be accessed whilst wearing the sac, even the lid (albeit with a few contortions and dislocations!). The side bottle pockets in particular are very useful, whilst the hip pockets are cavernous.
All in all a very well thought out rucsac, if a tad overbuilt.
Pros: Typical Macpac quality of construction and attention to detail. Very secure harness, moves well when running and cinches down tightly when cycling. The reflective piping is impressively refective - ideal for cycling through town in the winter.
Cons: I'm not sure that top tensioning straps are necessary on such a small pack. Not the lightest materials used in construction - really only the side panels, the rest is quite heavy duty. Similarly not quite as light as the stated weight, even with the heavy back panel removed and bits cut off it still comes in at 720 grams.
