If you plan on using a jacket like this with fewer layers beneath it, please keep this in mind when selecting your size.Regular Fit for Garments Designed to be versatile Regular Fit garments are not closely fitted making them ideal for cross-seasonal use and multi-layering. Regular fit garments are contoured, with room for movement.Slim Fit for GarmentsSlim Fit garments are designed to be worn closer to the body or over layers such as baselayers and light mid-layers. Slim fit garments are close fitting for maximum performance when moving dynamically.Expedition Fit for GarmentsExpedition garments are designed to be worn in colder conditions over more layers of clothing than our other fits and are oversized slightly to allow for this.
