The Women's Avail Hoody is a great thermal layering piece. The design is streamlined and the integrated thumbholes will help to minimize bulk when layered underneath. This piece, with a full front zip, will let you quickly cool down when you get too hot. The hood will come in handy if you forgot a hat, and also be the extra warmth layer over your hat on those cold winter days. The pill-and-fade resistant fabric will help this piece look good for many adventures to come and the Polygiene treatment will keep you smelling as good as you did when the adventure started.
