A key layering piece for winter camps, often thrown on to and from the trailhead, and just in general. And when the mercury is around 0F? The 200 wt fleece performs the same as my 100 wt for active use. No need to buy the most expensive fleece. My $25 fleece I purchased in 2010 is still going strong. And in 2017? The less expensive fleece is even better made!
