Men's Cotton Trunks FAQs
Cotton is a natural fibre that allows airflow, keeping you cool throughout the day. The soft texture ensures comfort, while its ability to absorb moisture helps prevent discomfort caused by sweating. Many people choose cotton trunks because they provide a snug yet flexible fit that supports movement without feeling restrictive. The natural softness of Men's Cotton Underwear reduces the risk of irritation, making them a go-to option for men who prioritize comfort in their underwear.
Looking for even more cotton comfort? Why not add Men's Cotton Socks or Women's Cotton Socks to your basket too and save 10% off your order?
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 both Cotton and Bamboo options.
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.
