Product Insights

The Whisper Sheer-Stripe Brief by Pump! combines knitted sheer stripes that intensify transparency under tension with an opaque double-ply contoured microfiber pouch, creating a visual tease while providing structured support and ventilation. The close cut, contoured pouch, and matte 40mm waistband deliver a sculpted silhouette, but buyers report divided opinions on all-day comfort due to potential seam digging. The fabric—a breathable, moisture-wicking blend with 14% elastane—offers nearly triple stretch and a smooth hand, though care requires cold wash and hang-dry to preserve fit and pattern. Ethically made in Pump!'s own Medellín factory, the brief earns a 4.9-star rating for its sensual aesthetic and comfort, though buyers advise ordering one size up for optimal fit.

  • Feedback on Pump fit and comfort

    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

  • Complaints about seam discomfort and daily wear

    I don’t find them comfortable enough for daily wear personally. Only have one pair (for that reason) and find the seems are very prominent and kind of dig in

  • Detailed review of Pump quality, sizing, and style

    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.

  • Advice to size up due to snug fit

    Different styles running kind of differently. But in my experience the waist is true to size. But they're are really snug. Im a 32 waist and usually do a M but I like a tighter fit. Most would probably size up.
