Mainline Menswear is one of those sites I end up going back to whenever I want something designer but don’t want to pay full price on the brand’s own website. I first found it when I was looking for a BOSS sweatshirt that had sold out elsewhere, and since then it’s become my go-to for staples like polos, trainers and jackets.

The first thing I usually do is head straight to the sale section because there’s nearly always something reduced. I’ve picked up Lacoste polos for around £50 instead of closer to £80, and I once grabbed a pair of adidas trainers that were about £30 cheaper than other retailers just by checking the sale filters first.

What I also like is that it doesn’t feel overwhelming to browse. You can jump between brands like Belstaff, Tommy Hilfiger or Armani quickly, which makes it easier to compare styles and prices without opening ten different tabs. If I’m close to the free delivery threshold, I’ll normally add something practical like underwear or a basic t-shirt instead of paying for shipping.

Before I check out, I always look for extra discounts because Mainline has quite a few ongoing ones that people miss. The student and key worker offers are worth checking if you qualify, and even the Strava discount is a nice bonus if you’re already tracking runs. And of course, I’ll always check NetVoucherCodes first to see if there’s a working Mainline Menswear discount code to bring the total down even more.

Shop the designer sale for up to 50% off

One of the easiest ways to save is to start with the Mainline Menswear sale section, where you’ll regularly find reduced designer clothing, footwear, and accessories.

• Look for discounts across jackets, jeans, trainers and accessories from brands like BOSS, Lacoste and Tommy Hilfiger.
• Seasonal clearances often include wardrobe staples like polos, hoodies and tracksuits at lower prices.
• Sorting by category or size can help you quickly find the strongest reductions.

Use verified discounts for students, key workers and youth offers

Mainline offers several ongoing discounts that don’t require a promo code.

• Students can unlock 10% off after verification.
• Youth shoppers aged 15–25 can access exclusive savings.
• Key workers, including healthcare, education, military and emergency services, can verify for additional discounts.

Unlock Strava rewards for active shoppers

Mainline also offers a unique Strava-based discount.

• Complete a verified 5K run via Strava to access 10% off full-priced items.
• Ideal if you’re already tracking fitness activity and want an extra incentive when shopping.

Enjoy Free Delivery

Delivery costs can quickly add up, so it’s worth planning your basket.

• Spend over £40 to qualify for free UK delivery.
• Orders placed before 4 pm on weekdays are dispatched the same day, which is helpful if you need items quickly.

Check new arrivals and bestsellers for seasonal promotions

Not all discounts are found in the sale section.

• New-season launches and bestselling items sometimes receive limited-time promotions.
• Checking these sections alongside sale categories can help you find reduced pieces before they sell out.
