Frequently Asked Questions
Everything you need to know about our premium essentials.
How do I ensure I am ordering the correct size?
We provide a comprehensive size guide on every product page. If you are between sizes, we generally recommend sizing up for a more relaxed fit or staying true to size for a tailored, athletic fit.
What is the Weldon Blue rewards program?
Weldon Blue is our loyalty program that offers tiered benefits. Members receive free shipping on all orders, and as you spend more, you unlock levels that provide significant discounts on every future purchase.
What is your Try-On Guarantee?
We want you to find your perfect fit. If you don't love your first pair of underwear, undershirt, or socks, we will send you a different size or issue a refund—and you get to keep the original pair.
How long does shipping take?
Standard shipping typically takes 3-7 business days within the United States. We also offer expedited shipping options at checkout if you need your essentials sooner.
What is your return policy for other items?
We accept returns and exchanges for unworn, unwashed items (excluding the Try-On Guarantee products) within 30 days of purchase. All original tags must be attached.
How should I care for my Mack Weldon garments?
To maintain the integrity of our technical fabrics, we recommend machine washing on cold and tumbling dry on low heat. Avoid using bleach or fabric softeners.
