I purchased the Matnras for a dual purpose backcountry/resort pant and they seem like they wil do a great job. These pants have a great construction with a heavy duty softshell-like (ie, soft hardshell) outer lined with fleece and polyester. The lining provides a little bit of insulation without making the pants too hot. The pants are very breatheable, but some extra (outer) thigh venting would expand the comfort range even more (also mesh lined vents would be nice). Tested them out looking for some October pow and ended up bushwhacking several miles and sliding down some icy rocks. They held up great and were comfortable the whole time in temps around freezing. I love the cut of the pants, a nice middle ground between tight techy pants and baggier stuff like Fly Low. I wear 32 waist pants and the Mediums fit me with some room to spare.
UPDATE: After a fair amount of touring in these I decided they are just too warm for that purpose due to the lining. Still bomber pants for inbounds and breathable enough for quick hikes, just not all day tours. More venting might have helped. Will probably return for Bombshell Bibs.
