Duluth Trading Armachillo

Cooling performance underwear praised for comfort, durability, and staying in place during heat.

Cooling in hot weather
Doesn't ride up
Long-lasting

Finally, I got 2 pairs of Armachillo from Duluth. Super impressed and will be buying more to replace the older stuff.
– Wildrubbaduckeee

I'm fully sold on Duluth Armachillo boxer briefs. The are great when it's hot out, they don't ride up at all like lots of others do.
– BBQShoe

Second Duluth. The armachillos are the best I’ve ever worn.

ExOfficio Give-N-Go 2.0

Travel-friendly synthetic underwear noted for longevity, odor resistance, and quick drying comfort.

Very durable
Odor resistant
Comfortable for daily wear

I wear ExOfficio Give N Go 2.0, Nordstrom boxers (the ones with the button), and Uniqlo. My underwear don’t fail often and all of those held up better than Smartwool.
– Elvis_Fu

I bought about 10 pair at the time. They are still going strong. There is no funky smell that is often associated with synthetic material, and the elastic is even still working.
– bgrubaugh

I've got about 15 pairs of these. They're extremely comfy and I've worn them every day for at least 10 years now.

Uniqlo Airism

Lightweight moisture-managing underwear valued for comfort, breathability, and fair pricing.

Reduces sweating
Comfortable
Good value

Uniqlo airism. Only thing that keeps my plums from getting soggy
– hazzatrazza

Uniqlo airism are the best and last a long time
– Big_Conversation2541

I tried some higher end brands, and sime budget quality brands, and am quite happy with uniqlo. The airism stuff makes me sweat a lot less in the summer.

MeUndies boxer briefs

Soft modal boxer briefs often described as comfortable, long-lasting, and non-chafing.

Very soft
Comfortable fit
Can last many years

I've been wearing the same meundies for 6 years. Bought some more 2 years ago and I really can't tell which are newer which are older.
– BlackholeZ32

I’ll never stop repping MeUndies dude. Got a couple pairs like 10 years ago just to try and they’re so nice.
– CrowForce1

I have been very happy with Meundies, specifically their boxer briefs. I have pairs that I've had since the Obama admin

Saxx Quest

Performance pouch underwear appreciated for support, comfort, and durability during active use.

Good pouch support
Comfortable for work and activity
Durable over years

Saxx Quest
– mrmelwhite

This. The quest are unbeatable. Had a couple pairs for years. Switched from exofficio to these.
– Beanhands

I agree with saxx, but for me its specifically the "quest" one. Don't buy full price though you can find sales and packs for cheaper.

Budget-friendly Costco underwear repeatedly recommended for comfort, value, and solid everyday durability.

Good value

Totally. Mine have lasted for years.

This right here. Get a pack or two of the Costco Kirkland boxer briefs. They last a couple of years with no issue
