We took the 308 Fit and translated it into a late-season, fleece-lined option. The Lined 308 Pant adds the features needed as temperatures become increasingly colder, including a breathable 2-layer construction with 37.5 Fleece that traps heat while actively exhausting moisture, and front-of-leg cargo pockets that add stash points for late-season kit you may need to toggle.  Finally, thigh zip vents are aptly placed to dump heat during high-exertion climbs or weighted-down packouts.
