My wife and I will be hiking in the great out-of-doors next month. We're not experienced hikers, nor campers; just out to see some wonders of the west. Though I'd love to take the 4x5, I will be carrying only my M4, a couple of extra lenses, and some Delta 100, in a sort of photo vest, for occasional opportunities as they may arise. But I will take my tripod, and we will be taking trekking poles. Therefor, I'm looking for a comfortable back carry case for tripod (and sometimes poles), both of which collapse to 27". The tripod is an old aluminum Cullman, perhaps 4 lbs., with a circumference of about 16" at the top, closed. A plain canvas carrier would be fine, if spacious enough for me to pad the inside. Suggestions sought. Thanks.
