Mainline Menswear Discount Codes July 2025

Shopping for men’s basics is rarely inspiring. It usually ranks somewhere between doing your taxes and descaling the kettle - necessary, sometimes oddly satisfying, never thrilling. But with the gravitational pull of overspending stronger than ever and trends cycling at the speed of a YouTube apology, it's a relief to find a few wardrobe essentials that don’t try to sell you a lifestyle in the process. Just decent clothes, reasonable deals, and - if you squint - some actual value.

The Eternal Return of the Triple T-Shirt Pack

There's something almost comforting about picking up a plain white tee and knowing it doesn’t care how many useless smart devices you own or whether you’re bulking or cutting. Which is why multi-packs remain a minor act of retail common sense. The HUGO Triple Pack Crew Neck T-Shirts are currently on sale for £32 (down from £45), and as far as brand-name cotton rectangles go, they tick every box: soft handle, decent shape retention, and a neck that holds up longer than most office chairs.

That said, it's worth noting these are slim fit. Not "sprayed-on indie band" slim, but tailored enough to look deliberate - as in, you’d probably notice if someone swapped yours for a two-for-ten Primark special. They're not oversized, boxy, or doing any architectural heavy lifting. They're just plain tees. And that’s probably the point.

BOSS, But Make It Multipack

BOSS - a label that, for better or worse, still carries connotations of mid-level management trying to buy respect - is currently offering a few variations of its 3-Pack Crew Neck T-Shirts at £45. The real utility here lies not in the logo, which is mercifully blink-and-you'll-miss-it, but in the fabric weight. These aren’t featherlight undershirts destined for a see-through demise after six washes. They’re sturdy, opaque, and come in useful colours - black, white, grey - with just enough structure to make them viable solo.

This version is probably the most versatile, leaning neutral, while this one edges into tonal-black-moodboard territory for those trying to dress like they've watched Drive too many times.

There are other packs - each subtly different depending on your preference for logos or stitching - but don’t expect transformative tailoring here. They’re T-shirts. They cover your torso. Sometimes that’s enough.

Diesel’s Take: Slightly Louder, Slightly Bolder

For those of us who occasionally glance at our reflection and think, "I could use a logo the size of a co-worker’s passive aggression," Diesel’s T-Box Lab Logo T-Shirt is gently waving from the sidelines. At £58, it’s not priced to be an everyday throw-on, but then again, this is Diesel - nostalgia wrapped in a Gen Z scroll fugue.

It wears well enough, and if you miss the early 2000s in a way that keeps you up at night, this will feel familiar. Just don’t look too hard for subtlety. It’s black, boxy, and says "DIESEL" in case anyone around you forgets consumerism is alive and well.

Deals, Delivery, and The Cold Logic of Checkout Buttons

Mainline Menswear is currently offering free UK delivery on orders over £40, which mildly encourages you to add something else to your basket you hadn’t planned - like socks, or existential dread. Returns are fairly painless, handled within 14 days with a full refund assuming you haven’t tried to live a full weekend in the item before sending it back.

Voucher codes pop up now and then - less frequently than they used to, but that’s the inevitable entropy of the online coupon universe. Sale sections remain the best bet for scoring lower prices, and with brands like BOSS and Hugo appearing regularly with discounts, it's not hard to plan your basics refresh without feeling overly manipulated by a seasonal PR push.

The Final Reckoning: Should You?

If you’re looking for T-shirts that will neither embarrass you nor ask much in return, these packs will do nicely. They're functional without being frumpy, branded without being brash. There's no life-changing innovation here - not even a moisture-wicking gimmick in sight. But sometimes, the most radical thing a shirt can be is just … a shirt.

And in a world increasingly crammed with infinite-scroll fashion and AI-generated slogans, there’s something quietly rebellious about going basic. Or maybe just incredibly practical. Either way, it’s cheaper than therapy.
