Differences between Regular & Tall Sizing
  • Tall sizes are 2" longer than Regular sizes in body length. 

  • Tall sizes are 1" longer than Regular sizes in sleeve length. 

  • If your size is not available in Regular, we suggest going down a size in TAL as a complimentary size. Equally if your size is not available in TAL, we would suggest going up a size in Regular. The extra length in Tall can in some cases accommodate a Regular size up, and the extra fabric in a Regular size up, can sometimes accommodate a taller silhouette.
Fleece Pants

Our fleece pants are in Alpha sizing. Identify your waist size to find your alpha size. Refer to chart below to find your alpha size.

Find your waist size.

Our pants are true to size. Sizing varies by brands. The best way to get the most accurate size is to measure a pair of pants that fit you well. Measure your pant's waistband laying flat from right to left, and multply that number by 2, that will give you your waist size. For example, if your pant's waist size measures 14 inches from right to left, your pant size is 28". Do not measure around your waist, but measure a pair of your pant's laying flat right to left to get best fit.

Measure your inseam.

The inseam is from the interior leg hem (bottom) to the interior crotch. Pro Tip: Use a pair of pants that fit you well. Measure them laying flat, along the inside seam from the bottom of the hem to the interior crotch.
