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.

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
