What's so special about this one?

This 34-litre day pack has got knobs on.

Sorry?

Well, not knobs because they would jab into your back. It has three features to make carrying things easier and more comfy.

What are they?

Jansport claims that a new design involving the straps and the back area reduces the pull on shoulders and back by 40%. It claims that super-absorbent padding gives greater stability and that a sweat-busting mesh whisks away, well, sweat.

What else?

It's got zips and pockets galore.

Does it work?

It certainly felt comfortable on a bike trip in Aldeburgh at the weekend.
