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.

Osni Poncho Liner - Underquilt - Cloak
The Osni ("cold weather" in Lakota language) Poncho Liner is multipurpose gear. It snaps into our Ponchos to be a liner, or as an Under Quilt for hammock use. Other uses: stand alone great coat, a sleeping bag - on long side, half bags, blanket, Woobie style, over quilt, hammock liner, Serape, and more. Insulated with APEX Climashield maintaining up to 1.25" loft for comfortable warmth. 3.6 oz is standard and best for most cases, 5 oz is bulkier and more for extreme conditions. Cover fabrics are ripstop nylon, or poly if noted, with water repellent (DWR). The Osni is also sort of REVERSABLE retaining all essential functionality, noting that the exterior color wraps to the inside on bottom edges and hood front. As with all our gear, choose your colors. Osni fully integrates into all our PSS Series Ponchos, the sizes are listed to match. MULTICAM NANOSPHERE is very highly water repellent yet breathable, limited availability. We make the Osni in the USA. "Osni Poncho LIner is a great piece of gear you will not want to be without, you will use it all the time."

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

PSS = about 58″ x 84″

PSSLB and PSSLE = about 58″ x 96″

PSSxL = about 58″ 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.
