Whether you're heading to the beach in California, a pool party in Texas, or a lake weekend in the Pacific Northwest, finding swimwear that feels right can completely change your relationship with water — and summer itself.
For trans and nonbinary people, traditional swimwear options often feel like a compromise. Designs built around binary body assumptions leave many people choosing between comfort and confidence, or simply avoiding the water altogether. That shouldn't be the case.
This guide covers everything you need to know about gender-affirming swimwear — what to look for, how different garments work, and how to find the right combination for your body and identity.
What Is Gender-Affirming Swimwear?
Gender-affirming swimwear is designed to help trans and nonbinary people feel comfortable and confident in aquatic settings. Rather than forcing bodies into binary swimwear templates, gender-affirming options are built to support a range of gender expressions and body types.
This includes swim binders for chest compression, swim trunks with room for packers, rash guards, and other garments that prioritize comfort, coverage and gender expression over conventional swimwear aesthetics.
Swimwear for Trans Masculine and Nonbinary People
A swim binder is the most direct solution for trans masculine and nonbinary people who experience chest dysphoria in the water. Unlike everyday chest binders, swim binders are made from quick-dry, chlorine-resistant compression fabric that maintains its shape when wet.
Transform swim binders provide effective chest compression without rigid internal paneling — meaning your ribcage can still expand naturally while you swim. They're designed for use in pools, at the beach, and in open water.
Our swim binder range includes both crop and tank styles to suit different body types and coverage preferences. Rinse in cold water after each swim to extend the life of the garment.
Swim Trunks and Board Shorts
For trans masculine and nonbinary people who pack, finding swim shorts with room for a packer is important. Look for swim trunks with a built-in liner or a secure internal pouch. Our swim shorts are designed with this in mind.
Board shorts offer more coverage and a relaxed fit that works well with a swim binder for a complete water-ready outfit.
Rash Guards
A long or short sleeve rash guard worn over a swim binder adds an extra layer of coverage and UV protection — practical for outdoor swimming and beach days. This combination is popular with many of our customers for the comfort and confidence it provides without drawing attention.
What to Look For When Choosing Gender-Affirming Swimwear
Compression Level
Swim binders provide moderate compression designed specifically for water activities. The compression is effective enough to flatten the chest while still allowing comfortable breathing during swimming. If you want maximum compression, consider wearing a swim binder under a rash guard.
Fabric Performance
Look for fabrics specifically designed for water use — quick-dry materials that retain their shape when wet and resist chlorine and saltwater degradation. Standard chest binders are not designed for swimming and can become heavy and uncomfortable when wet.
Fit and Sizing
Swimwear should feel secure and supportive without restricting breathing or movement. Measure your chest and follow the sizing guide on each product page for the most accurate fit.
Activity Level
Consider how you plan to use your swimwear. Casual beach days have different requirements to swimming laps or playing water sports. Our swim binder range is designed to work across all of these contexts.
Top Tips for a Comfortable Water Experience
- Try everything on at home before your first swim to ensure the fit feels right
- Rinse swimwear in cold water after every wear — especially in chlorinated pools or saltwater
- Choose quick-dry fabrics to move comfortably between water and dry land
- A rash guard over a swim binder adds coverage and sun protection for outdoor swimming
- If you pack, look for swim shorts with a secure internal pouch or liner
- Take your swim binder off and rinse it immediately after swimming — don't let it dry while still on
You Deserve to Feel Good in the Water
Swimming and water activities are for everyone. Whether you're at a competitive swim meet, a backyard pool party, or a quiet morning at the beach, you deserve to be there in swimwear that fits your identity — not swimwear that makes you work around it.
Explore our full trans swimwear range, including swim binders, swim shorts and rash guards, designed for trans and nonbinary people across the US.
Frequently Asked Questions
Can I wear a regular chest binder for swimming?
Standard chest binders are not designed for swimming. When wet they can become heavy and uncomfortable, and the fabric is not designed to perform in aquatic environments. Swim binders use quick-dry compression fabric specifically designed for water use.
How do I care for my swim binder?
Rinse in cold water immediately after swimming. Hand wash or machine wash in a laundry bag on a delicate cycle. Hang to dry in the shade — do not tumble dry as heat degrades the compression fabric. Avoid wringing the garment out.
Can I swim laps in a swim binder?
Yes. Our swim binders are designed to perform during active swimming including laps. The compression fabric moves with your body and allows your ribcage to expand naturally. Remove your swim binder if you experience any discomfort or difficulty breathing.
What size swim binder should I order?
Measure around the fullest part of your chest and compare to the size chart on the product page. Our team is happy to help with sizing questions — reach out via our contact page.
