Costco is a men's underwear paradise

  • Costco, the member’s-only warehouse store, sells more than just bulk cereal.
  • It also sells a variety of underwear and accessories, which men rave about.

You’d never guess that the place where you can buy 30 packs of toilet paper and breakfast cereal by the cubic foot would also be the place where you could get all your undergarment shopping done.

But it is.

Costco is secretly one of the best places for men to get every single undergarment they need. You’ll find quality socks, undershirts, belts, and even underwear – all by Costco’s Kirkland Signature private label.

It’s all in the high-quality manufacturers Costco sources from and the exacting standards they hold for the products that carry the Signature label.

Unfortunately, it’s a bit of a mystery who exactly manufactures these products, as both retailers and manufacturers prefer to keep mum about the relationships. If you can live with the uncertainty, then the rewards are plentiful – as are the steals, since the items are quite a bit cheaper than their name-brand counterparts.


My favourite winter socks, the Kirkland Signature Men’s Outdoor Trail Sock, is one of the best steals in all of men’s sockdom. A four-pack of the merino wool blend socks is a mere $US12 – an incredibly small amount of money for wool socks of this quality.

I’ve bought many over the years, and exactly zero have failed me so far. They’re warm, soft, and, most importantly, comfortable.

Buying a comparable pair from an established wool sock brand like Smartwool would have cost $US19 for one pair. Unfortunately, the socks are so popular, this year’s run is already sold out, and the resellers are offering the socks for as much as double the retail price. It’s worth keeping an eye out when they return in September.


Another of my favourite items from Costco is the Kirkland Signature Men’s Leather Belt. Though it costs a mere $US18, the belt is made with Italian full-grain leather, which is the absolute best type of leather you can buy for a belt. The belt has lasted me years and still looks just as great as it did on day one. It’s the perfect size, weight, and colour, and I have every confidence it will last me years and years to come.

A comparable full-grain belt might cost anywhere from $US50 to $US100. Another steal from the bulk giant.


Guys swear by the Kirkland Signature Men’s Crew Neck Tee undershirts and, from my personal experience, it’s easy to see why. The shirts are luxurious and thick, bucking the trend of off-brand clothing being weaker or thinner than their counterparts. They will last quite a long while.

It’s $US19 for a six-pack, which might be a bit more expensive than undershirts you’d find at Walmart or Target, but the quality is much better, and the cotton is thicker.


Though I have no personal experience with the buy-it-in-bulk chain’s Men’s Pima Boxer Briefs, many guys claim they’re some of the softest and durable they have worn. More importantly, they claim the underwear’s Pima cotton-spandex blend allows it to keep its shape and not ride up, which is one of the most important things to consider when buying cheap(er) underwear.

About $US13 gets you four pairs, which is much cheaper than department stores or mall brands.
