With my 7 year old Crumpler bag hanging together by threads I figured that my trip to the US would be a good time to evaluate one of our new bag suppliers, Pakuma. After looking into what was available to meet my needs I settled on the Pakuma Akura K1, a backpack suitable for laptops upto 17".
On receipt of the bag I was surprised to find it was extremely similar to the Crumpler bags (in fact you'd be forgiven, by me at least, for thinking the logo was Crumpler's own), but remarkably lighter. The laptop protection is excellent, and because the material the exterior bag is made of is thinner (which might mean it doesn't last the 7 years the Crumpler bag did) and lighter I felt there was more space for storage in the main part of the bag despite the entire volume being smaller. There's a couple of nice touches as well, with a headphone port in the top of the bag so you can keep your MP3 player in the bag whilst using it, and (essential for travellers) two mesh pockets for bottles. In terms of comfort I found this bag much better than my previous bag (although the shedding of 7 years worth of clutter may have helped this) and I will be sticking with it for the forseeable future; I will of course report back should there be anything to add.
Now I realise that this bag might not be as heavy duty as its (twice as expensive by the way) Crumpler equivalent, but for daily use in normal commuter situations I think its excellent value at around £45.
