Related Expert Advice articles

Fabrics

Synthetic: moisture-wicking, quick drying, durable, but can hold on to odor
Wool: moisture-wicking, odor-resistant, cooling in warm weather, can be less durable

Styles

Bikini: less rear coverage, thinner waistband, higher-cut leg
Briefs (women's): full-cut briefs offer more coverage in front and back; hipsters offer medium front coverage and back with higher rise
Briefs (men's): close fit and good support, but less thigh coverage
Boxer brief or boy shorts: snug fit, good coverage, longer cut extends down to the upper thigh
Boxers: looser fit, added coverage can prevent chafing but prone to bunching
Thongs: lightweight and quick-drying but provide the least coverage
Sports bras: compression and support during high-output activities like hiking and running

Find your fit

Must be close to skin to efficiently wick sweat; should fit comfortably snug
