Now that summer is here, I’ve been spending as much time outside as possible – long trail runs, hikes in the mountains, sweaty walks, and generally trying to soak up every bit of warm weather and sunshine. And for active women like myself, having a good sports bra makes SUCH a difference.
A bad one can ruin an otherwise beautiful run. Chafing, straps digging in, bouncing, overheating, constantly adjusting things every five minutes… umm no thanks.
I’ve been going down a bit of a rabbit hole lately researching running-specific sports bras, especially brands runners genuinely seem to love, and there are a few brands that kept coming up over and over again in running communities and Reddit threads, especially for trail running and long-distance comfort. And there actually are quite a few brands making more sustainable options now too, using recycled fabrics, bluesign-approved materials, lower-impact manufacturing, and longer-lasting construction.
One thing I’ve noticed personally: for running and hiking, I care WAY more about comfort, moisture management, and chafing prevention than ultra-compressive “armor” style sports bras. Breathability matters. Especially in summer.
Most sustainable sports bras are made from recycled nylon or recycled polyester blends. They’re not perfect (synthetics still release microplastics), but they’re generally far better than virgin petroleum-based fabrics, especially when the pieces are designed to last for years instead of one season. Some brands are also experimenting with natural fibers like organic cotton, TENCEL, and bamboo blends for lower-impact activities.
Here are some of the best sustainable sports bra brands worth looking into.
1. Janji
Trail-running favorite
Janji has become almost cult-favorite status in the running community lately, especially among trail runners and marathoners. Their bras are designed specifically for high-output movement and long distances, with thoughtful details like pockets, breathable fabrics, and minimal chafing seams. Their pieces use recycled materials and the brand also supports clean water initiatives globally.
The Janji Long Bra in particular gets a TON of praise for balancing support and comfort without feeling suffocating. I’ve just purchased the Pace Bra for my trail running adventures – I can’t wait to try it out!
Price range: ~$58–88 USD
🌍 US-based, ships internationally
2. Rabbit
Runner-designed performance bras
Rabbit is another brand that runners are genuinely obsessed with, especially for hot weather running. Their sports bras are lightweight, breathable, and designed by runners themselves rather than fashion companies trying to make activewear. Several pieces use recycled polyester blends and OEKO-TEX certified fabrics.
Their pocket bras especially get recommended constantly for long runs and races.
Price range: ~$55–75 USD
🌍 US-based, available internationally through running retailers
3. Runderwear
Minimal chafing for long runs
Runderwear focuses specifically on running underwear and sports bras, which honestly already makes me trust them more for actual performance. Their bras are designed with seamless construction and moisture-wicking fabrics to reduce rubbing and irritation during long runs or hikes.
They also increasingly use recycled yarns and lower-impact materials across their collections.
Price range: ~$45–80 USD
🌍 UK-based, ships worldwide
4. Patagonia
Best for hiking & outdoor adventures
Patagonia’s sports bras lean a little more outdoor/adventure-focused rather than hardcore race-day compression, but they’re incredibly durable and made with recycled nylon and Fair Trade Certified sewing. If you spend your summers hiking, backpacking, trail walking, or climbing, these are fantastic.
And honestly, Patagonia is still one of the strongest sustainability leaders in outdoor apparel overall.
Price range: ~$39–79 USD
🌍 Ships internationally
5. Girlfriend Collective
Size-inclusive and sustainably made
Girlfriend Collective makes some of the best-known sustainable activewear out there, using recycled water bottles and fishing nets to create compressive active fabrics. Their sports bras come in a huge size range and hold up really well over time.
Their styles lean slightly more gym/yoga/lifestyle than serious trail running, but many runners still swear by them for medium-impact activities.
Price range: ~$38–68 USD
🌍 Ships internationally
6. Boody
Soft everyday support
I know I mention this brand a lot, but it’s for good reason. If you’re looking for something softer for walking, hiking, yoga, or lower-impact movement, Boody’s bamboo viscose bras are unbelievably comfortable. They’re not the most hardcore running bras on this list, but for everyday summer movement and travel they’re really nice.
Their bamboo fabric is especially good if you’re sensitive to rough synthetic materials.
Price range: ~$20–45 USD
🌍 Australia-based, ships globally
7. Outdoor Voices
Lightweight and breathable
Outdoor Voices uses recycled polyester and nylon blends in many of their sports bras and tends to focus on movement that’s fun and relaxed rather than ultra-intense fitness culture. Their bras are lightweight, breathable, and great for hiking, walks, and moderate runs.
Price range: ~$45–75 USD
🌍 US-based, international shipping available
8. Népra
European sustainable activewear
Népra makes activewear using recycled polyamide and ethically manufactured fabrics in Europe. Their designs are sleek and minimal, and their sports bras work especially well for running, strength training, and hiking.
I also appreciate that they’re very transparent about manufacturing and fabric sourcing.
Price range: ~$40–75 USD
🌍 Finland-based, ships internationally
9. Icebreaker
Merino wool performance bras
Icebreaker is a really interesting alternative because many of their bras use merino wool blends instead of fully synthetic fabrics. Merino naturally regulates temperature, resists odor, and works incredibly well for hiking and long outdoor days.
Not necessarily the highest-compression option for intense running, but amazing for hiking and lower-impact adventures.
Price range: ~$50–85 USD
🌍 New Zealand-based, globally available
Honestly, I think sports bras are one of those things worth investing in if you spend a lot of time outside moving your body. A really good one can completely change how enjoyable running or hiking feels, especially in summer heat.
And thankfully, we’re finally at a point where you don’t have to choose between performance and sustainability anymore.
