Durable, comfortable, versatile
It appears that I have an earlier version of this unit; however the basic idea is the same. This is a durable peice of gear especially since I use it year-round as a day pack. I do end up with my probe sticking up through one of the zippers but you can interlock the toggles on them so they don't come apart casually, but you can still pull them apart when needed. It does have internal pockets for probes but they don't accomodate the probe I have. I would like the shovel blade pocket to be easier to get the shovel in and out of but it does fit, and the handle does fit right into the side loops. The two small mesh inner pockets near the top are nice; in my case they carry 1) compass, survey marker tape, headlight and 2) matches, lighter, tinder, space blanket instead of goggles but organization is always personal. The hip belt pocket has a clip for keys.
I actually like the extra webbing; one strap is detachable and this provides a lot of options if settling in to a location for a while.
