Plenty of last-minute Amazon Prime Day deals are still live, so it’s not too late to save big on the retailer’s summer sale event. Prime Day 2025 officially ends on Friday, July 11, but it’s not too late to score great deals on electronics, furniture, seasonal items, clothing, and more.
If you’re looking to stock up on some nice, comfy clothing and underwear, Prime members can get a $36 3-pack of Adidas Performance Boxer Briefs for just $17 for a limited time. One reviewer called them “the only underwear you need.”

Shoppers will have to get an Amazon Prime subscription to take advantage of this particular deal, but Prime Day’s a perfect opportunity to try out the service if you’re not a member already. For $15 per month, you get fast, free shipping on most purchases; members-only discounts; and access to the Prime Video library, full of classic movies, television shows, and great Prime originals.
These “irritation-free” athletic boxers are machine-washable and made of a soft, stretchy blend of 91% polyester and 9% spandex. They’re supportive yet breathable and quick-drying for all-day comfort, no matter what sport you’re playing or how hard you’re working. Exact pricing will vary based on color and size, but you’ll likely find the best price if you stick to the black-and-gray 3-pack option.
They’re available in about 29 different color combinations in total, with sizes ranging from small to 4X-large; there’s also an option to buy them in packs of six, rather than three. If you’re unsure what size to get, Amazon offers a handy sizing guide.
“I’ve bought these multiple times over the years, and they’re super comfortable, super durable, and have a great fit,” said one shopper. “They don’t ride up at all, and the waistbands seem to last for years as long as you buy the proper size.”
