The TREW Polar Shift is a light an easily pack-able layer that has a bit of primaloft going on throughout this layer piece. It works well with shells and adds a good bit of warmth. It’s also reversible so you can act like you have 2 jackets.

So there are a lot of puffy type layers that work with many shells but this is one of the lighter more adaptable layers for those that need some but not a lot of insulation. It’s very good for the mobile rider who is in cold backcountry conditions or those that need a little extra warmth to go with a shell on the mountain. Also it’s not bad on it’s own in moderate dry conditions.
