I have both models. The Tour is very good size for a day hike and I've used it quite a lot.

But the Day model is almost too big - it just doesn't ride right. I have never used it with the strappettes, which convert it into a quasi-day pack and I'm sure it would work better that way. however - I have several day packs which I'd prefer.

Really the Day model is too much of an in-betweener. If you want mine I'll give it to you at a good price!

Strongly recommend the Tour.
