When this model makes sense
You want a substantial crew to use within a complete cold-weather clothing system.
Fit and sizing
The manufacturer calls the cut regular, with some breathing room; try it beneath the actual jacket you plan to wear.
Trade-offs to consider
Expedition branding is not a guarantee of protection at a particular temperature or in wet, windy conditions.
