Product Insights
The Whisper Sheer-Stripe Thong Polyester from Pump! delivers a tailored, breathable design with knitted sheer stripes over a solid cotton lining for modesty, a double-layered pouch with supportive center seam, and microfiber piping that reduces chafing, but its compressive 11% elastane and close cut require sizing up one to two sizes for proper fit, and the back string may be too short for some, while the waistband stays flat and the black colorway minimizes contrast for a slimming silhouette; to preserve stretch, it must be cold-washed and hang-dried, and its moisture-wicking micromesh suits active days—made in Canada.
Verified claims
- Sizing guidance
- Community feedback consistently notes the thong runs small: the close supportive cut and compressive 11% elastane make sizing up one size the safe call, especially between sizes.
- Pouch support
- Double-layered pouch: outer 89% polyester/11% spandex, inner 60% polyester/33% cotton/7% spandex with center seam for support.
- Durability
- The 11% elastane in the thong's body loses stretch if washed in heat or tumble dried; cold washing and hang drying preserve recovery.
- Fit
- Buyers note the close cut runs small and may feel snug, especially for larger builds.
- Color
- Black colorway reduces visible skin contrast for a slimming look.
- Fabric design
- Knitted-in stripes won't fade, crack, or peel, and microfiber piping helps the edge finish hold its shape.
- Care
- Machine wash cold and hang to dry to preserve the sheer stripes and stretch.
- Hand feel
- Silky microfiber knit with bound edges reduces chafing.
- Stretch
- 11% elastane gives compressive fit with instant recovery; some buyers size up.
- Breathability
- Alternating sheer and opaque stripes promote airflow.
- Stripe construction
- Knitted stripes over a solid lining create a permanent pattern, with the lining providing coverage where the fabric turns transparent.
- Modesty design
- Double-layer front pouch: sheer stripes over a solid cotton-blend lining for modesty, with a supportive center seam that contours the front.
- Piping
- Microfiber piping around the leg openings and pouch prevents chafing and protects the sheer edges from fraying.
- Moisture wicking
- Moisture-wicking micromesh and stretch microfibre (89% polyester, 11% elastane) keep the minimal fabric area dry and comfortable during active days.
- Provenance
- Designed in Canada, adding local provenance.
- Waistband construction
- The thong has a 1.5-inch wide soft-hand elastic waistband with raised PUMP! branding and satin logos, giving a stay-put, premium fit.
- Fabric softener avoidance
- Avoid fabric softeners, which can coat the moisture-wicking polyester and degrade the elastane's stretch.
- Mesh-bag washing
- Wash the thong inside a mesh laundry bag to protect the sheer stripes from snagging on zippers or hardware.
- Double-layer front stretch
- The double-layer front combines an 89/11 microfiber outer with a solid 60% polyester/33% cotton/7% elastane lining, so it adds modesty and support without making the pouch stiff.
- Colorway sheerness
- The White colorway shows more skin through the sheer stripes, while Black provides darker, more discreet coverage.
- Fashion positioning
- The sheer-striped front panel lets the Whisper double as a fashion piece and a performance-oriented daily driver.
- Back string fit
- The back string is knitted from the same stretch microfiber as the rest of the garment (89% polyester, 11% elastane), so it has some give, but its length is fixed; sizing up is the practical workaround if the short string digs in.
- Show-through under clothing
- The sheer stripe is decorative rather than an all-over transparent net, so under most trousers or jeans it reads as a slightly bolder silhouette rather than actual show-through.

| Whisper Sheer-Stripe Thong Polyester: Choose this if you want a sheer-striped thong with a breathable, moisture-wicking micromesh and stretch microfibre build, a double-layered front pouch with a cotton lining, and a 1.5-inch softhand elastic waistband, in Black from sizes small to x-large. Note that one wearer reports Pump! thongs tend to run smaller, so sizing up may be worth considering. Care is limited to cold machine washes and hang drying—no bleach, tumble drying, ironing, or dry cleaning.[1,2,3,5,6,7] | Brown Micro-Perforated String Thong Nylon: Choose this if you want a minimal string-style thong in brown, available in sizes small through X-large, made from a stretch nylon blend (77% nylon, 23% spandex body with a 93% cotton lining) that the retailer describes as ultra comfortable. It features a wide elastic waistband with a large PUMP! logo, a contoured double-layered front pouch, and micro-perforated mesh fabric. Note the narrow side straps leave a deep cut under the waistband, so it suits those comfortable with a very revealing cut.[8,9,10] | Military Thong Nylon: Choose this if you want a low-rise thong in a stretch nylon-elastane microfibre, with a double-layered contoured front pouch and a cotton-lined cup, plus a mesh yoke that the brand says ensures breathability throughout the day. The soft elastic waistband, Y-shape back, and reviews-based support and comfort feedback (rated 4.9 by 91% five-star reviewers out of 34) suit buyers seeking a minimal, secure-fit style. Note that sizing reportedly runs small, so consider ordering one size up, and it comes in one colorway (Patterned Black) in sizes small through extra-large.[11,12] |

They look great, the fit awesome, they feel good, and they’re perfect. Whole hard to see in the photos, the black fabric is a stripped fabric where the alternating stripe is more mesh like

Pump thong comfort and sizing advice
They are comfortable, the string you can barely feel it. Just need to buy the correct size. In my case I use medium for boxers but for thongs I use XL, specifically for pump Large for some reason

Detailed Pump thong review: sizing, style, and comfort
PUMP is an excellent brand, the quality is high. But their underwear including their thongs tend to run smaller, accentuating your body if you’re fit, not so much if you’re not i.e. it cuts into you. I originally bought an XL when I was 110 kilos and I could barely fit into it, now I’m 89 kilos and XL is starting to feel a little loose. I’m not a fan of the large back with the small string style they have because it doesn’t look good in my opinion but I like their traditional thong - they fit well and compliment the body. The pouch holds everything for me.

Pump underwear sizing advice, including thongs
I have thongs, backless and jocks underwear from them and thing swimwear. For underwear I would size up as the materials are not really streatching and sizing is really on the smaller side. For swimwear I also went with one size bagger and they fit relaxed and nicely (no digging anywhere). I think you could get away with a normal swimwear size as the material is stretchier and you like to have a lowrise, tight and lifting look
