Underwear / Underpants — SuperBuy Spreadsheet
Underwear is a bulk-buy category. The SuperBuy Spreadsheet for underwear helps you filter by fabric composition, pack size, and waistband quality before entering the full catalog.
What to Buy in This Category
Boxer briefs, trunks, classic briefs, and thermal underwear.
How to Judge Quality
The waistband is the quality indicator — it should feel substantial, not like a thin rubber band. Check stitching around the fly.
Common Mistakes to Avoid
Elastic that rolls after washing, thin fabric that doesn't breathe, and sizing that runs small on Asian sizing charts.
Sizing Tip
If you are between sizes, size up. Asian sizing charts often run one size smaller than US/EU.
Material & Fabric Guide
Cotton-modal blends are the most comfortable. Pure polyester does not breathe well. Look for 95% cotton or higher.
QC Checklist
Waistband width and elasticity, stitching around the fly, leg band tension, and fabric transparency.
