Men's Cotton Trunks FAQs

It’s simple. Pick any 2 or more multipacks from our range of everyday essentials, add them to your basket, and mix and match as you like. Your 10% saving is applied automatically at checkout - no codes needed. Plus, free UK delivery is included with every order.

Socks and underwear wear out at roughly the same pace. Replacing single pairs creates a mix of old and new that never feels consistent. Buying them together resets your drawer in one go - same fit, same comfort, every day.

Larger packs also mean fewer orders, fewer deliveries and less time re-buying basics. You stock up once and you’re sorted for months.

At Spairs, our socks and underwear are sold in sensible multipacks so you can stock up once and save more over time. It’s the easiest way to stay stocked up while spending less. Browse all our multipack Men's Socks and Women's Socks offers here. 

Looking for even more everyday comfort and value? Shop multipack Men's Underwear and Women's Underwear.

Keyhole Boxer Shorts feature a longer leg length compared to trunk briefs, typically extending halfway down the thigh. This longer leg length helps prevent thigh chafing and offers a more secure fit. This style is particularly beneficial for those who prefer additional coverage and comfort reducing any chance the leg seams will 'ride up'.

Fitted Trunks are known for their shorter legs and snug fit. They have a low to mid rise (where they sit on the waist) and provide a sleek, modern look with a fitted silhouette. The shorter leg length means less fabric, which can be ideal for wearing under tighter pants or jeans.

Both Men's Underwear styles offer unique benefits, ensuring that you can find the perfect pair to suit your lifestyle. Better still our men's underwear is available in a choice of fabrics.

You should choose your usual waist size in inches. Our tagless Cotton Trunks run true-to-size and are designed with superior stretch for comfort and wearability.
