The Jack Wolfskin Moab Jam 18 is the best value daypack we've tested so far this summer.
It leans towards being a mountain biking pack but I’d be quite happy to use it for hiking as well since as is common with Jack Wolfskin products it has a stack of features, many that will come in useful on less demanding day hikes.
The main compartment has a hydration sleeve and port and is easily accessed through the top loading zipper.
You also get two trekking pole attachments, an integrated rain cover, anchor loops for your bike lights and – something I especially liked – a sturdy, compact and comfy harness and hip belt system and Delrin frame with a wide ventilation channel on the back panel.
This makes the pack easy to carry whether loaded to the max or relatively empty, which is ideal for a smaller sized day pack since they are often required to perform at one extreme or the other.
