MuleBuy Underwear/Underpants Spreadsheet Gateway
Underwear is the most practical category on the MuleBuy Spreadsheet. It is low-cost, lightweight, and a great way to hit minimum shipping weight without adding bulk. The full catalog covers boxer briefs, trunks, and compression styles. The spreadsheet tracks waistband elasticity, fabric stretch, and tag placement. The most common issue is the waistband losing elasticity after a few washes. The spreadsheet notes which batches use reinforced waistbands. For fabric, modal and bamboo blends are the most comfortable, while cotton is the most durable. The mulebuy reddit community rarely posts about underwear because it is such a low-risk category. That said, always check the QC photos for the waistband logo and the interior tag. The full catalog has a small but consistent selection of underwear, with restocks on popular styles.
Buying Tips
- 1Start with a multipack to test the waistband quality before ordering single pieces
- 2Check the fabric stretch percentage. More stretch means a better fit for different body types
- 3For compression styles, check the leg length. Some reps shorten the leg to save fabric
- 4Underwear is the best filler item for shipping. Add a multipack to your order without significantly increasing freight cost
