While all of Rab's garments are sized to these measurements, you will find that the cut on jackets designed for use in more extreme environments will be slightly more generous in the expectation that these designs will be used with additional/thicker mid-layers. 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 Rab's 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 GARMENTS: Rab's Slim Fit garments are designed to be worn closer to the body or over layers such as base-layers and light mid-layers. Slim fit garments are close fitting for maximum performance when moving dynamically.
EXPEDITION FIT FOR GARMENTS: Expedition garments are designed to be worn in colder conditions over more layers of clothing than Rab's other fits and are oversized slightly to allow for this.
