i have had great service from my WM dryloft apache. the extra duty outer shell makes it less subject to dampness on longer trips.
it is also the bag of choice to hand to my lady when she's with me. girls seem to run colder than guys, and she's quite the chilly little thing. so even in summer in california, the apache is a good call for the likes of her.
in any situation where the weather is colder than it can handle, well heck, it's too cold for my skill set as well. effectively, if the bag is at it's limit at night, i know the morning is going to be quite challenging. freezing hands, gloves on 100% of the time. cold feets. nasty winds, that whole lot of yucky stuff that it's only grace is the the bugs are down for awhile.
so what stands out ? for the apache dryloft, it's going to be solid service over a wide array of conditions. lots and lots of area under the graph.
note : some folks may find it confining. but in my op, the footbox is still to spacious.
in retrospect, i wish i'd had it overfilled a little bit. that would be perfect !
