⭐⭐⭐⭐⭐ Jordan Lee - Marathon Runner & Gym Trainer
"I’ve been using the Advanced Version of Calves Kelson's organic cotton boxer briefs for my daily training and long runs. The moisture-wicking fabric keeps me dry even during 10K sessions, and the seamless bulge pouch eliminates chafing completely. After 5 months of near-daily use, they still hold their shape and smell fresh—thanks to the silver-ion treatment. These outperform every other brand I’ve tried."Purchase Date: February 2025 | Usage Period: 5 months
⭐⭐⭐⭐⭐ Daniel Park - Financial Consultant
"I wear these under suits all week, and honestly, I forget I’m even wearing them. The mid-rise fit is snug without being tight, and the anti-static finish prevents clinging under wool trousers—game changer. I ordered the Pro Model with a subtle embossed logo for our company wellness kits, and clients keep asking where we got them. Worth every penny."Purchase Date: November 2024 | Usage Period: 7 months

"As someone who prioritizes eco-friendly materials, I was thrilled to find underwear that’s both organic and functional. The 92% organic cotton blend feels soft and breathable, and knowing it uses 70% less water than conventional cotton aligns with my values. I wish the packaging was fully compostable, but the product itself is excellent. Great for casual wear and light workouts."Purchase Date: January 2025 | Usage Period: 6 months

"We partnered with Calves Kelson to create custom-branded underwear for our members using the Professional Version. The digital printing captured our logo in stunning detail, and the 300-wash durability means these can handle heavy rotation. Members love the quick-dry performance post-workout. With a small MOQ of 50, it was affordable to test the design before scaling. Now we’re placing a 500-unit reorder."Purchase Date: September 2024 | Usage Period: 8 months

"I teach 90-minute hot yoga classes daily, and comfort is non-negotiable. These breathable, anti-bacterial boxer briefs stay cool and odor-free, even in 105°F rooms. The 4x faster moisture-wicking compared to regular cotton is real—no damp clinging. I chose the solid black Advanced Model with embossed logo, and it looks sleek and professional. My students have started buying them too."Purchase Date: April 2025 | Usage Period: 2 months
