I weight 72kg with jeans and a shirt.
Add Crispi Antarctics, winter trousers, thermals, jumper, shell jacket, gloves etc I'm up to 75kg.
Add a medium rucksack with, water, snacks, warm layer, pulk harness, pulk tracers I'm maybe 80kg max.
Here's Fischer's sizing.
Would 205cm be the obvious choice? I know everyone here recommends sizing-up but I'm a little worried that with the pulk I'll not have enough traction being in the lower end of the weight bracket.
