Designed foremost as an active insulation garment for extreme cold weather, the fit and details serve this purpose: upper arm pockets offer accessible storage even when the chest pockets are covered by body armour and load bearing vests. The elbows are reinforced with 500D Cordura, and these reinforcements double up as pad pockets for elbow pad inserts. Underarm ventilation zippers help lessen your thermal load during high activity levels.

The latest 2023 version has 2-way underarm ventilation zippers, and the hook & loop panels on the storm flap are reversed (hook on the flap, loop on the chest), which will reduce the possibility of unwanted hook & loop attachment to your cuff etc. The retiring versions are marked so in the size listing.

The L5 Thermal Jacket also functions as a static insulation garment and can be donned over your regular lightweight field uniform. However, unlike the L5 Thermal Anorak this jacket is not designed for wear over armour and load bearing gear.

L5 - Thermal Shell

The fifth layer of the Särmä TST Clothing System is designed for quick layering over your field wear, or for wear as a stand-alone cold weather uniform. Generous ventilation zippers minimize the thermal load of the layer, allowing the wearer added comfort. Camouflage prints and visible accessories are 100% NIR compliant.
