The Snugpak Poncho Liner features dedicated sleeves unlike older, square shaped poncho liners. The dedicated sleeves prevent chills when lifting your arms while wearing a poncho to keep you warm. The Poncho Liner also features a dedicated hood with a draw cord adjustment that allows you to customize the hood’s fit. The Poncho Liner has a comfort temperature rating of 45 degrees Fahrenheit, and a low rating of 36 degrees Fahrenheit, made possible with Snugpak’s Travel Soft insulation. Travel Soft is designed to be travel-orientated with its lightweight, compressible fibers that are less bulky than other insulations. The Poncho Longer also features Paratex, a durable, lightweight, windproof fabric that will keep you dry in inclement weather and keeps the poncho liner smelling fresh between washes. This Poncho Liner is equipped with the features you need to stay warm and protected from the elements on your adventures.
