activewear box FAQs
Can I control what's in my box, or is it truly random?
It's curated, not random. Our team hand-selects each box based on your size and current inventory. The specific styles, colors, and brands are a surprise — think of it like having a personal stylist pick your workout wardrobe. If you have specific preferences or restrictions, drop us a note at checkout and we'll do our best to accommodate.
What brands or quality level can I expect?
Moisture-wicking fabrics. Four-way stretch. Flatlock seams. Premium quality, curated for you. No fast fashion, no filler.
How do I choose the right size for my mystery box?
We've got you covered from XS to 3XL. When you place your order, you'll select your size and we build your box around it — every piece is chosen to fit that size. If you're between sizes, we recommend sizing up for a more comfortable fit in leggings and sets. Still unsure? Check our size guide or reach out before ordering.
Is an ActivewearBox actually a better deal than buying activewear on sale?
A single premium pair retails for $60–$90. Our 3PC starts at $29. The value speaks for itself.
What if something doesn't fit or I don't like an item?
Because our boxes are deeply discounted mystery items, we don't accept returns or exchanges on opened boxes. However, if an item arrives damaged or defective, we'll make it right — contact us within 7 days of delivery with a photo and we'll send a replacement or issue store credit.
When will the activewear mystery box ship?
Order today and it ships within 24–48 hours. Most U.S. orders arrive in 3–7 business days. Free shipping on orders $25+.
Is the activewear mystery box a subscription?
One-time purchase only. No hidden fees, no recurring charges, no commitment. Order once, get your box, done. Simple.
