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.

Sizing

Sized according to recommended user height and chest circumference. The fit is relaxed enough to allow the jacket to be worn over thick mid-layers and even a regular lightweight field jacket.

By tightening the hem drawcord and cuff hook-and-loop adjusters you get the hem and sleeves to stay right where you want them.

Material

The outer fabric is 100% polyamide ripstop, 70g/m², 70D, nonfluorinated water-repellent finish. The lining is 100% polyester. The retiring version materials were 98% polyamide and 2% carbon, ripstop.

Climashield Apex insulation, 100 g/m² (2.9 oz). This is some of the best insulation there is a fantastic weight-to-insulation ratio and great performance even in wet conditions. Apex is a continuous fiber filament; this means it does not need any attaching stitching as you would find on common polyester or down loft garments. By eliminating these stitches, we also eliminate possible cold spots, further adding to the insulating properties of the garment.
