In Our Opinion

The DMM size chart is accurate and reliable. If you prefer a looser fit and you are between sizes, we recommend choosing the larger size.

We are confident in the fit of DMM Climbing & Bouldering garments because:

  • We have tried the t-shirts on ourselves, in a full range of models and sizes.
  • We monitor customer returns.
  • We see customers wearing the t-shirts in our Rock Climbing/Outdoor Shop
  • We have been selling them for years! 

How to Measure Your Chest

Measure Guide
  • 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.
