Excellent report, well worth a Brownie point. I would like some re-working to pick up one point, so please re-post here after revising. You distinguish between day use on summit hikes or base camp-based day hikes and regular day hikes, a very valid and useful distinction. Can you provide a bit more detail as to why? Probably listing or summarizing pack contents will suffice, but keep that thought in mind as you look over the entire report.

<< The pack holds everything I need for a full day hike from camp to the
destination with the return to camp later that same day. >>
EDIT: Please let your readers know what "everything I need" is, as your differentiation between summit pack use and general dayhiking is central to your review.
<<I wouldn't use it as a daypack without being on a backpack trip because I carry more gear on that kind of trip. >>
EDIT: In the same vein, list (or summarize) what you add on a standard day hike.
<< This is the best little day pack considering its minimal weight. >>
EDIT: Same issue you don't use for straight dayhiking. Maybe "best little summit pack"?
<<Sometimes I would prefer the pack to be a little larger, but overall it has

Edit: Why do you think so so that you could use it on true dayhikes?
