Mack Weldon Coupon Codes & Deals
Mack Weldon makes the stuff men reach for every single day — underwear, tees, socks, sweats, sweaters and swim — and it puts the same amount of thought into a pair of boxer briefs as most brands put into a suit. The New York label built its name on fabrics that actually do something: AIRKNITx that moves moisture and dries fast, 18-Hour Jersey that holds its shape from the morning commute to a late dinner, and SILVER, which uses silver fibres to keep odour down. Nothing flashy. Just well-made basics that feel better than the price suggests, and that you can buy again in the same size, same fit, same fabric, year after year.
Best deal: 20% off your first order over $125. Create an account, sign up for email, and the saving applies to full-priced items — it’s the biggest single discount Mack Weldon offers right now.

About Mack Weldon
Mack Weldon started with a simple frustration: men’s underwear hadn’t really changed in decades, even though the fabrics around it had. The brand set out to rebuild the drawer from scratch, and it now covers the full run of everyday essentials — underwear, undershirts and tees, socks, sweatpants and hoodies, sweaters, shorts and swim. The focus stays narrow on purpose. Rather than chasing every trend, Mack Weldon refines a small set of products and the fabrics they’re made from, so a tee you buy this year feels the same as the one you bought two years ago — and fits the same way, too.
Three fabrics do most of the talking. AIRKNITx is a quick-dry, breathable knit built for underwear and active days; 18-Hour Jersey is a soft, stretchy cotton blend made to be worn all day without losing its shape; and SILVER weaves real silver fibres into the fabric to fight odour naturally. The range also leans into practical details — flatlock seams that don’t rub, waistbands that stay put, and fits that run true to size. Prices sit in the middle of the market: you pay more than a supermarket multipack, but the pieces are built to last longer, which is where the value actually shows up. Gift cards run from $50 to $200 if you’re buying for someone else, and Afterpay is available at checkout.
How to save at Mack Weldon
- Start with the 20% off first order. If you’re spending $125 or more on full-priced items, create an account and sign up for email first — that single step is the biggest saving on the site.
- Bundle your underwear. The Bundle & Save offer takes 10% off underwear multipacks, so stocking up on three or more pairs costs less per pair than buying them one at a time.
- Watch the 3-pack pricing. The 3-Pack AIRKNITx Boxer Briefs is listed at $96.90, down from $102, and it always ships free — a small saving on its own, but a real one if you buy in bulk or top up every few months.
- Join Mack Weldon Rewards before you check out. Blue members earn 5% cashback, and once you’ve spent $500 you move to Silver at 10% cashback with free shipping from $100; spend $1,000 and Black gives you 15% cashback with free shipping on every order. Points convert at 100 points to $5 — just remember rewards expire after 60 days, so use them before they lapse.

How to use a Mack Weldon code
- Shop mackweldon.com and add the items you want to your bag. If you’re using the first-order offer, make sure your order comes to $125 or more in full-priced items.
- Create an account and sign up for email if you haven’t already — the first-order discount is tied to your account and email sign-up, not to a code you type in.
- Head to checkout and look for the promo code box. If you have a code, enter it exactly as shown and check the discount appears before you pay. Most Mack Weldon offers right now are deals, so the saving is already reflected in the price and there’s nothing to type in.
Good to know before you buy: the 20% first-order discount applies to full-priced items only, so sale items in the same basket won’t be discounted. We haven’t verified that Mack Weldon codes can be combined with other offers, so don’t count on stacking two discounts on one order. If a code doesn’t apply, check the order total first — the first-order offer needs $125 of full-priced goods — then check you’re signed in to the account you registered with. There’s no student or military discount listed on the official site, so don’t expect one at checkout. The Holiday Shop is live as a seasonal feature, but it doesn’t carry a stated percentage off, so we haven’t turned it into a coupon.
