-36C in Saskatchewan today while testing my layering system..it worked!

Version 12.0 it seems but this layering system worked like a charm!

Torso -Merino wool base layer TAD gear
Second layer -Swandri bush shirt
Third layer -Polartec fleece -TAD gear
Hard shell-Arc’teryx Alpha LT

Head-Balaclava merino wool TAD gear
Merino beanie

Eye Protection - REVISION eyewear goggles ECWS

LEG base layer - Arcteryx COLD WX
Insulated pants -Arcteryx
Wool socks
Salomon Quest 4D GTX
Arc’teryx mitts

In the above combination it wasn’t overly bulky and my body temperature stayed consistent over 90 minutes so all in all an 8/10 winter system for -36C low wind and sun out.
