The best boxers known to man. Or at least one man, me.

Slam DomeOctober 16, 2025

These boxers are so great that I'm actually wearing boxers again after over a decade of exclusively boxer briefs. I've been wearing separatec boxer briefs for a while now, buying either the modal set or the bamboo material. These boxers are made of modal, which is the greatest underwear material or really any sort of clothing material that I've ever encountered. Silk feels nice on your hands, but less so cramped against your body for long periods of time in confined spaces such as pants. Modal has the fabulous quality of being both soft and slick, but mostly incredibly overwhelmingly soft. These underwear fit very loose and flowy, with good coverage and a fly button, if you are so inclined. They would work well as walking around the house boxers as they leave a little something up to mystery. However they also work great stuffed into pants whether tight or loose, and are great for heat regulation. I highly recommend these over the same companies polyester version of the same cut of underwear. You just don't want to compromise on the material like that, or like me you will have a sweaty day. Somehow they've managed to make loose flowy boxers not look like Grandpa's sleepwalking again. It's probably due to the incredibly flowy nature. Overall if you're a person that always wears boxers, this is a no-brainer. But if you're a person who's been wearing boxer briefs for years, these are probably the boxers that will give you a moment of pause, and consideration of perhaps some days loose underwear would be preferable. If you've been wearing briefs this whole time, I'm not sure anyone can help you. But maybe these could serve as your intervention. Read more

Premium underwear for a mid-range price. The quality fits the price :)

Amajohn PrimeOctober 9, 2025

I was never a person to seek out anything but the cheapest of the cheap underwear. I'd go out and get a deal for 10 pairs of boxes for under 20 bucks. But they were just that; Cheap in price and cheap in comfort/feel. They I see this 3 pack of silky smooth boxers, promising breathability in the material and I knew I needed it. Man, it does not disappoint! So comfy throughout my work day, work outs, and especially to wear at night time. Having a good quality pair of underwear really changes my entire sleep comfort, and I'm so glad I took the plunge. Easily washable due to the breathability of the materials, and is also less likely to hold smells. Even after a tough workout, the smells don't hold as much as my other pairs of boxers. Size is true to fit, but if you're on the fence of size, they are very stretchy! Price at Review: $34.99 Overall: ★★★★★ Silky smooth feel: ★★★★★ Value: ★★★★★ Material quality: ★★★★★ Day and nighttime comfort: ★★★★★ ☆☆☆☆☆ Read more

Men's sleep wear

I buy too muchNovember 13, 2025

Super soft and cozy I own a few Modal cloth Pj's so when this came up I decided to buy for my teen and it was a hit does fit as standard size and has a good amount of stretch. This is a good buy or as a gift to any man in your life. Read more

Comfortable fit, true size/chart, not irritating to skin!

Alex MSeptember 27, 2025

Like that title says: They are a comfortable fit. Neither too long or too short. A nice wide band keeps them from cutting into your waist or riding up/down hips. The size and corresponding chart are both accurate. I'm not normally a 'boxers' guy -- I like the boxer/briefs that have become so common. Saw these, they are a great color set, so I decided to go ahead and jump back into a pair of boxers. Good choice! I have very sensitive skin. I'm fairly particular about the fabric. I was a bit reluctant, because Modal is a semi-synthetic fabric, like rayon. Modal is made from the cellulose/fiber of the beech tree. Rayon, mixed with cotton, spandex, or other fabrics, always feels ... not quite clingy, not quite sticky, not quite scratchy, but a bit of all of them. I was nervous I'd feel that with the Modal as well. I can happily report that they're not driving me nuts... Quite the opposite, they're very comfortable! Disclaimer: this is a Vine review. I received the product as a sample to review. If the item(s) had not matched their description, been of low/poor quality, or was otherwise not deserving of the rating, the rating would have been lower. Read more

Love this brand for comfort and quality

KentSeptember 30, 2025

I absolutely love the brand Seperatec. I’ve been buying their 3-pouch underwear for years now and I won’t go back to anything else. The taller waist band on newer Seperatec is comfortable for hours of wear, it never cuts into my waste like smaller wait bands. I saw this 3-pack of sleep underwear and thought I would try them out since I love the quality from this brand. I had to lookup “Modal fabric”, it’s in the rayon family but it comes from beech tree pulp instead of bamboo. I love my 95% bamboo rayon Seperatec for day use - casual wear, running, biking, etc. and they have held up for years. See picture for reference. On the left is a Men’s medium of this sleep boxers after the first wash. On the right is a Men’s medium of their 3-pouch that is a year old and gets worn at least once/week. Disclaimer: yes I ordered this from Vine Voices, but I buy products on Amazon weekly and I’m pretty picky about price vs. quality so I’m writing this review as if I spent my own hard-earned money on this item.

Loose and breathable

D. LouieSeptember 28, 2025

Looser than others. Other pairs have a generous pouch that snuggles the boys. This set are a bit looser than others and quite comfortable. T he elastic is wide so it doesn’t bunch or pinch. Read more
