Intraknit Bikini Underwear – Women's

Built for active women who want merino comfort on long days on trail or in travel, the Intraknit Bikini is our top pick for performance underwear. Smartwool's Intraknit construction zones ventilation and support exactly where you need it, so moisture and heat don't build up. The merino blend handles odor naturally, making it a solid choice for multi-day trips without re-packing extras.

• Intraknit™ engineered knit structure places ventilation zones and support precisely where your body needs them most
• Merino wool blend naturally resists odor and regulates temperature — works in Southern summer heat and cooler mountain mornings alike
• Body-mapped seamless design zones cut down on chafing during high-output activity and all-day wear
• Soft elastic waistband sits secure without digging in under a pack hipbelt or waistband
• Lightweight and low-bulk — packs flat for travel and layers cleanly under tights or shorts
