Frequently Asked Questions
Think about what you spend on boys' underwear over 16 years: a few packs every year, plus emergency runs when he runs out. That adds up to well over $1,000 — for lower-quality underwear, bought in a rush, over and over again. The Lifetime Pack gives you 100 quality pairs, once, for less than $10 each. One decision. Zero underwear stress for the next 16 years. That's the value.
For hygiene reasons, we can't accept worn underwear back. But we stand behind our Comfort Fit Promise. If there's a quality issue or major sizing miss, contact us and we'll do our best to fix it — including exchanges for unused pairs. We want you and your son happy in Top Underwear.
We divide your 100-pair pack across boys' and men's sizes so your son is covered at every stage from age 2 to 18. After checkout, we'll confirm his age and build, then recommend the best size breakdown for your son.
Yes. This is a one-and-done bulk shipment. You'll receive all 100 pairs in one box so you can stock today's drawer and store the future sizes until he grows into them.
If something feels off, reach out to us. We offer size support and can help with exchanges on unused pairs so you're not stuck with the wrong fit. We'll always work with you to make it right.
Yes. Our cotton-blend fabric is soft, breathable, and designed for everyday comfort from toddlers through teens. If your son has very sensitive skin, we recommend trying a few pairs first before opening the rest of the pack. If they're not a hit, contact us and we'll make it right.
Most parents dedicate a small bin, drawer, or closet shelf to the "underwear vault." Keep the future sizes folded and stored, then rotate new pairs into his drawer as he grows. It's simpler than it sounds — one shelf and you're set for 16 years.
