Make sure you have proper support before hitting the trail.
These are our top picks for the best hiking bras.
Patagonia Active Mesh Bra
This super soft sports bra is great for medium-impact activities such as backcountry hiking and backpacking. Constructed of a stretchy yet supportive polyester/spandex blend in a seamless design that won't chafe, the Active Mesh Bra features mesh panels for added breathability. Patagonia's miDori bioSoft adds moisture-wicking, quick-drying comfort, while HeiQ Fresh keeps odors at bay on the trail. The compression sports bra features a straight neckline and v-back tank top-style straps. It comes in XS-XL rather than typical bra sizes and retails for $45.
This full-coverage trail running sports bra provides medium-impact support with a combination compression/encapsulation design. Seam-free molded cups keep things in place with a fully encased underwire between them to prevent the dreaded uni-boob. The gel-filled adjustable wide straps and hook-and-eye closure provide a comfortable customized fit. The nylon-spandex blend fabric is finished with a moisture-wicking treatment. Available in cup sizes up to E, the Brooks Maia bra fits just about any woman hiker and provides extra support for larger-chested women at $58.
Icebreaker Merino Siren Bra
Constructed of a merino wool, nylon, and elastane blend, the Ice Breaker Siren is a low-impact hiking sports bra that's incredibly breathable and wicks moisture away from your skin. The merino also naturally helps to regulate body temperature and resist odors through long, sweaty hikes. The adjustable straps and bottom band are non-constricting and soft to prevent chafing. The v-neck design allows for inserting bra cups for more coverage and is available in XS-XL sizing for $50.
Most of these sports bras, as well as other important hiking gear, are also easy to find on Amazon and REI.
