Which pack should I buy for daily wear?

The Boss Five Pack of Stretch Cotton Trunks is the workhorse buy: soft waistbands, proper stretch, and enough pairs to rotate through a week. Gymshark's Sports Tech pack is the pick if most of your day involves a gym bag.

What fabric actually works in Indian humidity?

Stretch cotton for daily wear because it breathes, and poly blend sports fabrics like Gymshark's tech knit for training because they wick and dry fast. Pure synthetics all day in 90 percent humidity can chafe; rotate fabric types by activity.

How does sizing run across these brands?

Boss and Hanes based Supreme packs follow standard international waist sizing and fit true. Gymshark runs athletic and snug through the thigh, so size up if you have heavier quads. Waistbands should sit firm without rolling when you sit.

Trunks or boxer briefs: what is the difference?

Trunks are shorter in the leg with a square cut, better under slim trousers and shorts. Boxer briefs run longer down the thigh and stop chafing on long walks or runs. Most drawers in this climate want trunks for office days, briefs for movement.
