The side panels are made from Polartec Power Stretch Pro to give you optimum mobility for those backcountry tours that involve hiking up a powder capped peak. Since the Radium is semi fitted, it hugs your body comfortably, so layering on colder days is a breeze.An active fit keeps the Radium close to your body so you can layer on top of this fleece on snowy days. This lightweight jacket is also easily compressible for quick storage, which is essential in multi situational trips. And luckily the two handwarmer pockets are always there for your numb fingers, even if you have a harness or pack on.
