The Fit

Outdoor Research come in three fits, standardised across their entire apparel line. Be sure to choose the style most suited to your chosen activity for optimum fit and comfort.

  • Trim Fit: Trim fit, loose enough for layering with freedom of movement. Great for backcountry skiing and snowboarding, mountaineering and running.
  • Standard Fit: Moderate fit - not too tight nor loose. Fits over base and mid-layers for freedom of movement. Great for trekking, hiking, travel and casual wear.
  • Relaxed Fit: Loosest fit. Roomier and more progressive fit. Designed with a longer length and softer drape. Great for backpacking, hiking, skiing and casual wear.

  • How to Measure Your Chest & Arm Length

  • Wear just an undergarment or nothing at all.
  • Stand up straight with your arms hanging by your sides and breath normally.
  • Run a soft tape measure under your arm pits over the largest part of your chest and across your shoulder blades.
  • The tape measure should be snug, but not tight.
  • Ask a friend to run a soft tape measure from the centre of the back of your neck, across to the tip of one shoulder, then down the outside of your arm to your wrist bone.
