Some questions and answers are automatically generated.
Do these run large or small in size?
Several reviewers report that these run large. Multiple customers across different sizes mention ordering a larger size than usual and finding them roomy, with one noting they'd order a smaller size next time, and another saying they should have ordered small instead of medium. Most pairs fit well for those who select their true size.
Are these comfortable for all-day wear?
Yes. Reviewers consistently praise comfort, with many noting they wear them regularly for everyday activities including jogging. The flat waistline is specifically highlighted as preventing digging or discomfort, and the cotton fabric is described as soft and well-made.
How is the quality of the material?
Reviewers consistently report good to excellent quality. The 100% cotton is described as thick, warm, and soft, with multiple customers noting the material feels durable and well-made.
Is the cotton too warm for summer?
One reviewer noted the cotton is thick and warm, suggesting it may not be ideal for summer wear. Most other feedback focuses on comfort and softness rather than warmth, so personal preference and climate will play a role.
How much does the leg elastic hold?
One reviewer mentioned the leg elastic could use more support. Most other reviewers do not comment on the leg elastic specifically, focusing instead on the waistline and overall fit.
Are these a good value for money?
Yes. Multiple reviewers specifically praise the value, noting the pack of six offers good value for the price and quality. One mentioned it's difficult to find quality Y-fronts in general retail, making this a useful option.
Will the fit work if I'm between sizes?
Since these run roomy, if you're between sizes it may be worth sizing down. Several customers with in-between measurements or those who preferred a tighter fit found their chosen size larger than expected and wished they'd ordered smaller.

Customers praised the 100% organic cotton Y-front underpants for excellent quality, comfort, and value. Many noted "well made using good material" and appreciated the breathable fabric.

Tremendous purchase
I purchased traditional Y fronts from Sock Stack in a medium size and have found these 100% cotton Y fronts to be comfortable as well as a good fit.

Store FAQs
Got a question about our socks, materials, or your order? Find quick answers below. For anything else, our UK-based team is always happy to help.
Product questions
Are Sock Stack socks OEKO-TEX® certified?
Yes — many of our socks and underwear are made from OEKO-TEX® Standard 100 certified materials, independently tested and verified free from harmful substances and chemicals. This means every certified pair is safe for your skin, your family, and the environment. Look for the OEKO-TEX® badge on individual product pages to confirm certification.
How do I care for my Sock Stack socks and underwear?
The majority of our socks, underwear, and thermal underwear are machine washable for easy everyday care. We recommend washing at 30–40°C on a gentle cycle to preserve the fibres and extend the life of your products. Turn bamboo socks inside out before washing to maintain their antibacterial properties. Thermal underwear should be washed at 30°C to retain its insulating properties. Avoid tumble drying on high heat — air drying or a low tumble setting keeps everything in the best condition for longer.
Do you sell socks for specific occupations or activities?
Yes — our range covers a wide variety of needs and lifestyles. We stock breathable cotton work socks ideal for long shifts and office wear, cushioned compression socks for running and sports, moisture-wicking trainer socks for the gym, thermal slipper socks for home, and gentle non-elastic diabetic socks for sensitive feet and poor circulation. Whatever your day looks like, we have the right sock for it.
Do you sell men's underwear and thermal underwear?
Yes — alongside our extensive sock range, Sock Stack stocks premium men's underwear and thermal underwear built for comfort and everyday practicality. Our men's boxer shorts are available in breathable cotton and bamboo blends for all-day comfort. Our thermal underwear range includes thermal vests and long johns — ideal for cold weather, outdoor work, and winter layering. All available in multipacks so you can stock up and save.
What is the difference between bamboo and cotton socks?
Both are natural, skin-friendly materials — but they perform differently. Our bamboo socks are naturally antibacterial, moisture-wicking, and hypoallergenic, making them ideal for sensitive skin, sweaty feet, or all-day wear. Our cotton socks are breathable, durable, and great for everyday use across all occasions. Many customers keep both in their sock drawer — bamboo for active days, cotton for everyday comfort.

Beautiful rope storage baskets, very well made and sturdy. Ended up ordering a couple for my daughter too, she was soo impressed with them. Thank you for a great service too.
I bought 2 x large throws in teal colour. I was astounded by the quality for the.prive and the speed with which they arrived...I'll certainly order from you again
I bought these in sage to match my bathroom. I already knew they were thin because of others reviews but that was precisely why I got them. They dry quickly, preventing that musty smell developing. Every piece is perfect, no wonky edges.
Tequested size exchange due to Larger than expected fit.
I was pleased with the quality of the product and arrived in good condition, but the 2XL was too large for my requirements for it was not the right fit for me. I therefore returned the item on 13/08/2026 via Royal mail and requestedban exchange for an XL size.
The returned process was straighforward, and I am looking forward to receiving the replacement. Overall, my experience with the product and ordering process has been positive.
Have ordered these items before and loved them. However evri decided to leave the parcel with a so called neighbour 17 doors away and on a different street... Luckily the gent took the time to come and find me so parcel finally delivered
