I have a spike camp, and it gets used as a carry on for traveling. I don't hunt with it. It's not big enough for my day gear + a quartered out animal, and even if it was, I wouldn't put myself through that torture.

This time of the year, I day hunt almost daily, as the days aren't long enough to make camping worth it. The same pack I use for 7 days, is my daypack. It does not hinder me one bit.
