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 in both marketing and product design - very similar to the brand we were creating. We embraced the name, flipped it a bit and made it ours.
It’s all about the fabric and construction. We use Lenzing Modal® (made of 100% natural beechwood) which is anti-microbial (prevents odor), manages moisture and keeps you cool. When blended with cotton it actually creates a softer, more luxurious feel. Seams are designed to stretch and recover, and we use different materials to keep you comfortable where it counts (18-Hour Jersey, micro pique cool zones, stretch rib between legs).
The 18-Hour Jersey
Our signature blend of long staple cotton, Lenzing Modal and Lycra, is our choice for all undershirts and classic underwear styles. The result? We believe it’s simply the softest most comfortable underwear on the market today. To ensure the least amount of garment shrinkage, the fabric is allowed to rest peacefully, unrolled for 18 hours before cutting and sewing.
Daily Performance Wear
Mack Weldon is designed "for daily wear" but many of our wearers loved how the product performed in the gym and on the court. It's meant to fit close to the body, but never tight or restrictive so it's a good balance of compression and long-term comfort. As for the undershirts, the cotton/modal blend wicks moisture and keeps everything cool on hot days.
So, while not designed specifically to wear for sport, it's nice to know that you can.
Labels on the Outside
When designing the line, we were inspired by some vintage military issue product that had print on the outside of the garment for easy sorting and identification by the wearer. So there is some purpose there that we thought was unique/relevant. Also, we didn't want the lettering to come between your skin and the soft 18-hour jersey.
We accept credit cards backed by the major providers on our website: Visa, Mastercard, American Express, and Discover. Unfortunately we cannot accept some debit cards. If you are having trouble checking out, please email us at firstname.lastname@example.org so we can help.
Apple Pay: If you have an iPhone with Apple Pay enabled you can pay using Apple pay from either your desktop or phone. On the desktop, you must have MacOS Sierra or above; on iOS, you must be running iOS 11 or above. Apple Pay is not supported if you visited our website through an in-app browser, like Facebook's in-app browser.
PayPal: We accept PayPal on our website (desktop or mobile). If you have a balance in your PayPal account, your PayPal balance will be used first before your backup funding source (which you will select at the time of purchase). Funds are always used from your PayPal balance first; you are not given a choice to use or not use your PayPal balance. However, the PayPal window you see may incorrectly lead you to believe you are paying from your credit card or bank first, even when you have a PayPal balance. (Even though the purchase screen does not give you an option to not use your PayPal balance, it is always used first if it exists in your account at the time of your purchase. We regret the confusion caused by this interaction with PayPal as it is out of our control.)

XT2™ is a fiber created by combining pure silver with cotton. The silver's natural antimicrobial and anti-odor qualities are woven throughout the entire product. It is not a chemical formula or finish treatment, so it never washes out.
Don't worry, you can wear Silver through a metal detector. However, don't wear it through an MRI or other highly-sensitive machines.
We introduce new underwear colors 6 to 7 times a year, and less often for other products. True Black, Blue Night, Bright White and Cloud Burst are "core colors" that don't change. The other colors are seasonal and are not restocked. So if you see a color you like, order it today because it will sell out soon.

Gift cards do not expire, cannot be replaced or refunded if lost or stolen, cannot be returned and cannot be exchanged for cash except where required by law. Store credit, promo codes and other discounts may not be used to purchase gift cards. We reserve the right to revoke gift cards which were purchased fraudulently. Be wary of gift cards sold on eBay for less than the gift card amount. Often, these gift cards were purchased fraudulently. We cannot be responsible if you are the victim of this kind of scam. You should report fraudulent gift cards to ebay's support department.
The purchase of a gift card itself is non-taxable, but when you use the gift card the items you purchase may be taxable. If they are, tax will be assessed on your purchase at the time you use the gift card. (The money on the gift card can be used to pay for goods, shipping, or tax.)
Where can I find a promo code?
The "apply promo code" option within our checkout flow facilitates returns or exchanges for current customers. We don’t believe promo codes offer the best value for new customers because we don’t think you should have to search the internet for codes that most often don’t work. Instead, we created the Savings Meter, so you can save whenever you’re ready to stock up:
The Savings Meter gets you:
Free shipping on domestic orders over $50
10% off orders over $100
20% off orders over $200
These discounts are applied automatically as you shop, no need for any promo codes.
Plus, after you place your first order you'll earn a spot in our loyalty program, Weldon Blue. As a member, you’ll have free US shipping on all orders, plus the 10% and 20% discounts. Lock in the 20% discount on all orders of any value after spending a total of $200, at once or over several orders. Learn more about Weldon Blue here.
We don't partner with any coupon or discount websites, and promo codes posted on them are posted without our permission and cannot be honored.
