A very lightweight and breathable loft jacket with Climashield insulation. Packable enough to fit right in your pants' cargo pocket. Designed for use as an insulating mid-layer under your regular field jacket, can also be used as an outer layer during static breaks or other light activities.
The L3 is primarily designed for wear as an insulating layer under your field jacket but also functions when donned over your other clothing as a quick means for extra warmth when pausing for a break in cold weather. Thus the simple design, very low profile, and one single breast pocket on the left-hand side, easily accessed after opening the front zipper of any jacket worn over the L3. The construction and insulating properties are comparable to a modern lightweight summer sleeping bag.
The third layer of the Särmä TST clothing system, designed to be worn over a base layer of merino wool and under a field uniform or other outer shell. L3 garments come in two styles, unlined wind wear and lofty thermal wear with Climashield insulation. Lightweight, quick-drying, and highly breathable fabrics guarantee effective moisture management and great packability.

Pro-Tip: The L3 is also a clever choice if you want to extend the temperature range of a lightweight sleeping bag; just use it as a thermal pyjama! The materials and construction really serve this option.
The retiring version was sewn in Estonia, and the new version is sewn in Poland.
