Fit notes
Performance-focused with a Scandinavian-influenced minimal aesthetic. Running tights are designed for runners, not general gym use. Excellent weather jacket. Narrow cut reflects the brand's road-running heritage.
Watch out for
Hip cut runs narrow for pear shapes — size up or try a different brand. Limited colour range by design. Not appropriate for non-running activities.
