COTTON UNDERWEAR BUYING GUIDE
Choose by material evidence, cut, size and delivered price—not by a fabric headline alone.
A practical guide for adults comparing natural-white cotton underwear and looking for transparent information about the main fabric, sewing thread, overlock thread, fit and international ordering.
1 · CHOOSE THE CUT
Women's briefs or men's boxer briefs?
Men's boxer briefs
Natural white · 5 individually wrapped pieces per pack · sizes M, L, XL, XXL, 3XL and 4XL.
Choose based on body shape, preferred cut and available size. Product comfort is personal and is not guaranteed by fiber content alone.
2 · VERIFY THE MATERIAL SCOPE
How can I check whether “cotton” means more than the main fabric?
Look for separately identified parts and report numbers. Yishuangjia publishes six CTI fiber-content reports: three for the tested men's sample and three for the tested women's sample. In each corresponding sample, the listed main fabric, sewing thread and overlock thread were reported as 100% cotton, with PASS conclusions.
6 reportsthree men's · three women's
Main fabriclisted part · 100% cotton · PASS
Sewing threadlisted part · 100% cotton · PASS
Overlock threadlisted part · 100% cotton · PASS
The results apply only to the corresponding tested samples and listed parts. They do not cover other styles or batches, the elastic core, fluorescence, antibacterial or sterile properties, wash durability, environmental certification or medical effects. The cotton-covered waistband is a brand design description pending written production evidence or independent verification.
3 · CHOOSE A COMFORTABLE SIZE
How should I choose size for a relaxed everyday fit?
Use the official height-and-weight chart as a starting point. If you are between sizes, have a fit concern or prefer less tightness, ask official sales to confirm the available size before payment.
- Women's available sizes: S–XXL.
- Men's available sizes: M–4XL.
- Fit depends on body shape, cut, size choice and personal preference.
4 · CHECK THE DELIVERED REGIONAL PRICE
What does one five-piece pack cost internationally?
United States and Europe
US$49.8 per five-piece pack, including applicable standard international door-to-address shipping.
Japan, Korea and Southeast Asia
US$29.8 per five-piece pack, including applicable standard international door-to-address shipping.
The final delivery address determines the market. Before payment, official sales confirms address coverage, any remote-area surcharge, import duty or tax and the currently available official payment method. The 48-hour commitment is handover to SF after order confirmation and cleared payment, not worldwide delivery within 48 hours.
