Mammut are grounded in the principal of active clothing that follows the natural movement of the body with every garment designed to enhance, not restrict performance and motion.  Mammut garments come in a variety of 'fits'. Check the product description to see which fit applies:

Slim: Close fit intended for unrestrictive stretch with freedom of movement for active pursuits. Cut to account for likely combinations of layering.

Athletic: Dynamic cut, defined body shape, pre-shaped sleeves.  A combination of both performance and comfort.

Regular: Close athletic cut with minimal tailoring.  Cut for greater freedom of movement with comfort and room for layering.

Loose: Loose and casual fit with generous cut of the pants around the thighs and knees.

In Our Opinion

Sizings tend to vary between brands and the above size information, taken from Mammut's own guide, accurately represents the best fit. Mammut is designed for a more 'fitted' style. If you are between sizes and require room for layering please choose the larger size.

We are confident in the fit of Mammut garments because:

  • We have tried the garments on ourselves, in a full range of models and sizes.
  • We monitor customer returns.
  • We see customers wearing the jackets in our Snowboard/Ski Shop
  • We have been selling them for years! 

How to Measure Your Chest

  • Wear just an undergarment or nothing at all.
  • Stand up straight with your arms hanging by your sides
  • Breath normally and 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.
Measure Guide

Jacket Dimensions

We strongly recommend that you never measure a jacket to determine the chest size you need.  Actual garment sizes differ substantially from the dimensions quoted in the table at the top of this page because the manufacturer makes allowances for:

  • The wearing of mid and / or base layers beneath the jacket
  • The freedom of movement required for skiing and snowboarding
  • The cut and style of the jacket
  • The insulation which may or may not be included in a particular jacket.

All of the above will differ depending on a jacket's specific design.  A jacket's physical dimensions will always be significantly greater than your actual chest measurement but this difference will also vary from jacket to jacket.
