Women's Bighorn Shirt Jacket is a lightly insulated jacket for cooler days from spring to fall. Sort of a shirt, not quite a jacket, the in-betweener you'll need for camping trips or hiking the fall trails. The 80g of synthetic insulation adds that extra bit of toasty oomph to make it through the chill.
