The Glacier Delta has always been a versatile, staple mid-layer that you can depend on to take the edge of chilly days. This classic two-tone fleece is constructed from Polartec Microfleece fabric which is quick-drying and will keep you feeling toasty throughout the day. A convenient zipped pocket on the left arm gives you a great place to stash small essentials while the zipped neck design allows you to manually vent the garment when active.
