Mack Weldon Promo Codes — Up to 70% Off

New customers can save 20% on their first order of $125 or more. Regular customers can save up to 20% through underwear pack bundles, plus additional savings through MW Rewards points and seasonal sales that can reach up to 65% off select items.

Free shipping kicks in at $150 for orders within the United States. Orders under $150 have a standard shipping fee of $8, so hitting the threshold often saves you money even if you add an extra item.

You earn points on every purchase that convert to future discounts at a rate of 100 points for $5 off. Level Two members who spend $200 in a year get 20% off every purchase for the next 12 months. The program is free to join and starts earning rewards immediately.

Yes, Mack Weldon's Build Your Own pack feature lets you customize your bundle while still getting pack pricing. You can mix and match styles, colors, and sizes to create exactly what you want while saving up to 20% compared to individual item pricing.

Orders of $250 or more earn you a free wallet plus free shipping. The wallet is a quality piece that normally retails separately, making the $250 threshold a sweet spot for maximizing value on larger orders.

Most promotional codes, including the new customer 20% discount, apply only to full-priced items. Sale items are typically excluded from additional discounts, but you can still earn MW Rewards points on sale purchases.

The 15% Community Heroes discount for military, first responders, healthcare workers, teachers, and government employees can be used once every six months. Verification is required through GOVX, and the discount applies to full-priced items.

Mack Weldon offers free returns and exchanges on unworn, unwashed items within 30 days of purchase. They also have a Try On Guarantee for underwear — if you're not satisfied with your first pair, they'll replace it or provide a refund.

Most promotional discounts cannot be combined with other offers. However, you can typically earn MW Rewards points on discounted purchases, and spending thresholds for free shipping and free gifts still apply when using discount codes.

After entering your code at checkout, your order total should update immediately to reflect the discount. If the code doesn't work, check that you're meeting minimum spend requirements and that your cart contains eligible full-priced items.
