Hood/collar: closed without squeezing the face.
Between two sizes → choose the larger one (durability + mobility).

FAQ — Pyrenex Size Guide

I am between sizes: which one should I pick?
The larger one, especially if you wear a sweater/blazer: you keep the comfort and the longevity of the garment.

Regular or Slim: how to decide?
Regular for layering (sweater/blazer); Slim if worn alone, for a clean silhouette.

Sten Parka: same size as Spoutnic?
Most of the time yes; if you add a blazer + thick knit, go +1.

Child: do I choose by age or height?
Always by height. If the child is between sizes, take the size up.

Does the shiny finish (Mythic) fit smaller?
The perception may be more fitted. If you are between sizes or broad-shouldered → +1.
