I'm glad to see that my daypack is similar to others. I have people tell me all the time that I am carrying too much stuff. As for head lamps, I have started using on that clips onto the brim of a cap. It is a LED that weighs 1.24 oz with 4 lithium batteries in it. Distributed by www.trailblazerproducts.com
No way to attach it to a toque but I wear a ball cap even in winter and wear the toque over top. Brim helps protect my eyes from branches etc. And now holds my light.
