Osni (pronounced oos-nee)means “cold weather” in the Lakota Indian language, and is the perfect name for this new outerwear gear. It started out as a Poncho Liner and then we blew off the doors and made something really great. Check it out below.

The Osni Insulated Hoodie Pocket matches your Osni Cloak, it is insulated just like your Osni. Gives a warm place for your hands. If you use your Osni in reversible mode the pocket stitching may be visible. It will match your primary or outside shell fabric. If you already ordered an Osni in preorder, you can just order here and we'll add it.

The Osni is sized to fit our Poncho line since it’s primary intention is as a Poncho Liner and an Under Quilt for the hammock made from the Poncho.

You will see the typical poncho sizes listed in the size drop down, we’ll note here the sizing.

PSS = about 61″ x 84″

PSSL = about 61″ x 96″

PSSxL = about 61″ x 108

Note: a smaller size Osni can fit a larger size poncho as the snaps are referenced off the shoulder, so for example you could use a PSS size Osni in a PSSxL poncho.
