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 Cloak - Multipurpose Use
The Osni ("cold weather" in Lakota language) Cloak 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 maintaining up to 1" loft for comfortable warmth. Cover fabrics are ripstop nylon with water repellent (DWR) unless noted. The Osni is also REVERSABLE retaining all essential functionality. As with all our gear, choose your colors, 10 choices inside and out. Osni fully integrates into all our PSS Series Ponchos, the sizes are listed to match. We make the Osni in the USA. "Osni Cloak is a great piece of gear you will not want to be without, you will use it all the time." ROBIC 1.2 oz nylon now available for extra toughness. NOTE: NEW xWide versions - Choose xWide in size, choose only XW fabrics in color choices. Tip; a standard width Osni will fit any poncho even xWide, but will be slightly gathered in width, not really noticeable due to the loft of the Osni, but if you want the full width get the xWide.

Insulation is APEX which gives the Osni 1″ average loft, excellent warmth

Outer shell and inner cover fabrics are breathable nylon ripstop with water repellent coating. All fabrics are suitable for normal use outdoors, 1.9 oz fabrics are tougher than 1.1 oz, for extra strength choose ROBIC for the outside cover. There are a couple fabrics that do not have water repellency they will be noted as “no DWR” in drop down of fabric selection.

Camo Variations: Woodland is the standard familiar color pattern, Woodland Urban is the same pattern but with Grey, Black, Tan, and brown colors. MARPAT AOR2 is the same pattern as the standard but has lighter color palette, lighter greens, no Coyote brown and is pure finish no DWR.

ROBIC nylon is 50% stronger and 2 1/2 times more tear resistant than standard nylon fabrics.

For xWide options choose xWide in size choices, fabrics are limited for this width so be sure to choose fabrics with XW in the drop down description. Even if you have an xWide poncho you can still wear our regular Osni’s underneath, but if you need to take advantage of the full width of an xWide in the Osni then choose the xWides.

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 58″ x 84″

PSSL = 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.
