Thanks Ron

How do you find the 350? I'm
Looking at getting this exact bag, but unsure exactly what it will fit. I'm looking for a lighter alternative to my nature trekker aw II for when I don't have to carry a lot of gear and want room for snacks and water etc.

I have he Lowepro 350 fastpack, great bag. Well built and plenty of room, great all around travel bag.

Just returned my Lowepro after receiving my Guru, its a great bag, was going to keep it along with the guru but what really puts me off is where the zip opens for the camera, the guru you need to take the bag off to take the camera out as its behind your back, much safer in a crowded space.
