How does the underwear fit? caret-down

You can find the waist measurements for all of our underwear below.

  • S - 28-30"
  • M - 31-34"
  • L - 34-36"
  • XL- 36-40"
  • XXL - 42-46"

The waists on our underwear are designed to accommodate a range of sizes, but if you fall in between sizes and prefer a looser fit, the larger option may feel and fit better.  Garment measurements can be found on the individual product pages by selecting the "Size Guide" button. Below is more qualitative fit guidance:

  • 18-Hour Jersey Boxer Briefs - The 18-Hour Jersey fabric fits close to the skin without being constricting.  The inseam of 18-Hour Jersey Boxer Briefs is 6" in all sizes, but since we use a gusset instead of a traditional inseam, the way we measure it may be different from other brands. 
  • 18-Hour Jersey Trunks - The 18-Hour Jersey fabric fits close to the skin without being constricting.  The inseam of 18-Hour Jersey Trunks is 3" in all sizes, but since we use a gusset instead of a traditional inseam, the way we measure it may be different from other brands.
  • 18-Hour Jersey Briefs - The 18-Hour Jersey fabric fits close to the skin without being constricting. 
  • 18-Hour Knit Boxers - The 18-Hour Knit Boxers are made with the same fabric as our 18-Hour Jersey underwear, but with a looser fit. They have a button fly at the crotch and a covered waistband.
  • Silver Boxer Briefs - The Silver fabric is mostly cotton, so while it's meant to fit close to the skin, it's not as close-fitting as our other fabrics.  The inseam of Silver Boxer Briefs is 6" in all sizes, but since we use a gusset instead of a traditional inseam, the way we measure it may be different from other brands.
  • Silver Trunks - The Silver fabric is mostly cotton, so while it's meant to fit close to the skin, it's not as close-fitting as our other fabrics.  The inseam of Silver Trunks is 3.75" in all sizes, but since we use a gusset instead of a traditional inseam, the way we measure it may be different from other brands.
  • AIRKNITX/AIRKNITX 8" Boxer Briefs - The AIRKNITX fabric is a microfiber blend that's ideal for exercise. It's flyless and close-fitting for extra support, with four-way stretch that moves with you. Because of the elasticity, if you're on the lower end of a size range, you can comfortably size down. The inseam of AIRKNITX Boxer Briefs is 5" in all sizes, but since we use a gusset instead of a traditional inseam, there may be some variation in the actual fit.  The AIRKNITX 8" Boxers Briefs are a modified version that adds 3" to the inseam to wick away moisture and prevent riding up while exercising.
  • AIRKNITX Trunks - The AIRKNITX fabric is a microfiber blend that's ideal for exercise. It's flyless and close-fitting for extra support, with four-way stretch that moves with you.

  • 24/7 Woven Boxers - Our Woven Boxers are tailored to be less bulky but still looser-fitting. You can find the outseams of the Woven Boxers below. The outseam is the measurement along the outside of the leg, from the top of the waistband to the leg opening. 
  • Merino Long Underwear- The Merino Long Underwear is made with a blend of Merino wool and a natural cellulose fiber that provides stretch and durability. The fabric fits close to the skin. Since the Long Underwear are full length, different sizes have different inseams.

Who is Mack Weldon? caret-down

Mack Weldon is about the fusion between old-school quality and modern day technology. During our brand creation, we discovered Weldon, an early 20th century underwear company.  Weldon had a lot of similarities to the brand we were creating in both marketing and product design. We embraced the name, flipped it a bit and made it ours.
