The best underwear for rowing and paddle sports in 2026 comes down to three things: a fabric that doesn't trap moisture against your skin, a cut that stays put through a full stroke, and coverage that matches how long you're actually on the water. Best overall: Balance Thong for erg and strength days. Best for long water sessions: Elevate High-Rise Bikini. Best for low-impact paddling: Support Bralette. None of LunaLeila's pieces are built as technical sports gear, and that's fine — the job here is skin health and comfort around the workout, not compression.
- Balance Thong wins for erg and strength days under compression leggings, $29 — buy it.
- Elevate High-Rise Bikini is the pick for long kayak or SUP days at $29, stays put and covers more.
- Support Bralette handles dragon boat and low-impact paddling for $39 with a wide, wireless band.
- Harmony Triangle Bra is for the cool-down after paddling, not the session itself, at $45.
- None of these are compression sportswear — pick based on moisture management and coverage, not athletic support claims.
Why this matters
Rowing and paddle sports keep you wet for long stretches — sweat under a unisuit, splash from the water, humidity inside a drysuit. That combination is exactly what synthetic underwear handles badly: polyester and nylon trap moisture against skin and create a warm, damp environment where bacteria and yeast multiply. An estimated 75% of women experience a yeast infection at least once in their lifetime, and damp fabric sitting against skin for hours is a documented contributing factor.
Bamboo lyocell behaves differently. It's naturally more breathable and moisture-wicking than synthetic blends, which is why a piece like the Balance Thong works well as a base layer under leggings on erg days, even though it wasn't engineered as athletic gear. In 2026, most rowers layer this kind of underwear under a unisuit or compression short rather than relying on it alone for support.
The underwear itself won't make you faster. It will decide whether you're comfortable, dry, and chafe-free by the time you rack the oars.
What makes the best underwear for rowing and paddle sports
- Moisture-wicking fabric that doesn't hold sweat or splash water against skin for hours
- A fit that doesn't ride up mid-stroke or under compression leggings
- Breathability for sessions that run 60-90+ minutes on open water
- OEKO-TEX certified materials with no synthetic dyes or hormone-disrupting finishes against sensitive skin
- Coverage matched to intensity — a thong for under fitted layers, more coverage for a full day on a board
- Quick to dry and change out of once you're off the water

1. Balance Thong: best underwear for rowing during erg and strength days
The Balance Thong is a high-hip, leg-lengthening cut designed as an everyday piece, not a performance garment. On erg mornings or lifting days that lead into a paddle session, it disappears under compression leggings with no visible line, and the bamboo lyocell handles sweat better than a cotton blend would over a two-hour block.
Balance Thong pros:
- No visible panty line under fitted leggings or unisuits
- Naturally stretchy fit that moves with a full range of motion
- Bamboo lyocell breathes more than synthetic thong styles
- Comes in multiple colors, useful for layering under lighter fabrics
Balance Thong cons:
- Minimal coverage means it's not the pick for a full day exposed on a board
- No compression or support element — it's a base layer, not sportswear
Balance Thong pricing: $29 per piece, no bundle claims here — check the current lineup on the product page.
Best for: erg training, strength sessions, and any day where the underwear sits under other fitted layers.
Verdict: Buy if your rowing routine is mostly indoor or gym-based and you're layering under leggings.
2. Elevate High-Rise Bikini: best underwear for rowing and paddle sports on long water days
The Elevate High-Rise Bikini is built from LunaLeila's Luna-Boo Bamboo Lyocell and sits higher on the waist than the Balance Thong, which means more coverage for a full afternoon in a kayak or on a SUP. That extra coverage matters when you're getting in and out of a boat, adjusting a PFD, or sitting in wet gear for hours.
Elevate High-Rise Bikini pros:
- More coverage than a thong cut, useful for long, exposed sessions
- High-rise waistband stays in place without digging in
- Buttery-soft bamboo lyocell feel against skin
- Available in black, beige, brown, and white
Elevate High-Rise Bikini cons:
- The high-rise cut can feel warm layered directly under a wetsuit bottom
- Not designed for compression or muscle support during paddling
Elevate High-Rise Bikini pricing: $29, same price point as the Balance Thong with more fabric coverage.
Best for: kayaking, canoeing, or SUP sessions that run long and involve more time exposed to sun, water, and gear.
Verdict: Buy if your paddle days are measured in hours, not intervals.
3. Support Bralette: best underwear for rowing and dragon boat team paddling
The Support Bralette is a bandeau-style, wireless silhouette with a wide underband and adjustable straps. It's the pick for lower-impact paddling — dragon boat, recreational rowing, steady-state paddling — where you want to feel held without a structured underwire digging in for the whole session.
Support Bralette pros:
- Wide underband distributes pressure instead of a thin wire
- Wireless design is comfortable for long, seated paddling
- Adjustable straps let you dial in fit as you layer up or down
- Works as easily off the water as on it, so no separate bra for the drive home
Support Bralette cons:
- Less lift and lock-down than a structured sports bra during sprint intervals
- Bandeau shape isn't built for high-impact bounce control
Support Bralette pricing: $39, which puts it between the thong/bikini pieces and the Harmony bra.
Best for: dragon boat practice, recreational rowing, and any low-impact paddling where comfort matters more than compression.
Verdict: Buy for steady-state paddling; Skip it for sprint-focused training where you need locked-down support.
4. Harmony Triangle Bra: best underwear for rowing recovery and the cool-down
The Harmony Triangle Bra is a sensual triangle cut with an underband and a scaled hook-and-eye closure, made from OEKO-TEX certified bamboo. This one isn't for the workout itself — it's for the hour after, when you've toweled off, changed, and want something soft against skin that's been damp and worked hard.
Harmony Triangle Bra pros:
- OEKO-TEX certified bamboo fabric, hormone-conscious against sensitive skin
- Scaled hook-and-eye closure for a customizable fit
- Soft triangle cut that feels good on tired, post-session skin
- Available across six colorways
Harmony Triangle Bra cons:
- Triangle cut provides little structure, so it's not for the paddling itself
- Not designed with moisture-wicking performance as the primary spec
Harmony Triangle Bra pricing: $45, the highest price point on this list.
Best for: the recovery window after a paddle session, not the session itself.
Verdict: Buy for post-workout comfort; Wait if you're specifically shopping for something to wear during the paddle.
How we ranked
Each piece was measured against the six criteria above: moisture handling, fit stability, breathability, fabric certification, coverage-to-intensity match, and how quickly it transitions from wet gear to dry clothes. The Balance Thong ranks first because erg and strength training make up the bulk of most rowers' weekly hours, and that's where the moisture-wicking, no-line fit earns its keep most often in 2026.
Which underwear should you choose for rowing and paddle sports?
If you're mostly training indoors or lifting before a row, start with the Balance Thong. If your sport is kayaking, canoeing, or SUP with hours of exposure, go with the Elevate High-Rise Bikini for the extra coverage. Dragon boat and recreational paddlers do better with the Support Bralette's wireless, wide-band fit. Save the Harmony Triangle Bra for after — it's a recovery piece, not a performance one, and pretending otherwise would be dishonest about what it's built for.
None of these replace a technical sports bra or compression short if your rowing program is competitive and high-impact. What they solve is the quieter problem: staying dry, breathable, and chemical-conscious during the hours you spend wet in 2026, whether that's on an erg or a river.
FAQ
What's the best underwear for rowing?
The Balance Thong is the best underwear for rowing when training on an erg or lifting, since its bamboo lyocell fabric wicks moisture better than cotton or synthetic blends under compression leggings. For long days on open water, a higher-coverage piece like the Elevate High-Rise Bikini works better.
Should you wear regular underwear under a rowing unisuit?
Yes, many rowers layer breathable underwear under a unisuit for hygiene and comfort, especially on longer sessions. A moisture-wicking, no-line piece like the Balance Thong avoids added bulk while still managing sweat.
Is bamboo lyocell underwear good for sweat and moisture during paddle sports?
Bamboo lyocell is more breathable and moisture-wicking than polyester or nylon, which makes it a better choice for sweaty or wet conditions. It won't trap heat and moisture against skin the way synthetic blends do over a multi-hour session.
Can the wrong underwear cause a yeast infection after paddling?
Damp, non-breathable fabric held against skin for hours is a known contributing factor to yeast overgrowth, and roughly 75% of women experience a yeast infection at least once. Breathable, quick-drying fabric and changing out of wet underwear promptly both reduce that risk.
What underwear works best for kayaking and SUP?
The Elevate High-Rise Bikini works best for kayaking and SUP because its higher coverage and stay-put waistband hold up over long, exposed sessions. It sits higher than a thong cut, which matters when you're in and out of a boat repeatedly.
Do bamboo thongs work under compression leggings?
Yes, a leg-lengthening thong cut like the Balance Thong sits without a visible line under compression leggings. The naturally stretchy bamboo lyocell moves with a full range of motion instead of bunching.
How often should you change underwear after a wet paddle session?
Change out of wet underwear as soon as reasonably possible after a paddle session, ideally within an hour or two. Damp fabric held against skin for extended periods raises the risk of bacterial and fungal overgrowth.
Is cotton or bamboo better for on-water sports?
Bamboo lyocell dries faster and wicks moisture more effectively than cotton, which tends to hold water once saturated. For sports involving splash, sweat, or humidity, bamboo lyocell is the better-performing fabric of the two.
One last thing
The piece most rowers skip buying is the one for after: something soft and breathable to change into once you're off the water. The Harmony Triangle Bra's OEKO-TEX certified bamboo makes more sense for that hour than it does for the paddling itself — pack it in your gear bag, not your race-day kit.
