Bamboo Boxer Shorts FAQs

Bamboo Underwear is generally softer, more breathable, and better at moisture-wicking compared to Cotton Underwear and other synthetic alternatives. Bamboo fibers naturally regulate temperature, helping you feel cooler in the summer and warmer in the winter. They are also naturally hypoallergenic and antibacterial which helps prevent odour build up and provides all-day freshness, making bamboo boxer Shorts suitable for people with diabetes, eczema, or sensitive skin.

 

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!

 

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

Our amazing, ultra-stretch Cotton Underwear and bamboo Boxers, Briefs and Fitted Trunks also feature our signature, soft brushed elasticated waistbands and tagless printed care labels for total all-day comfort and zero irritation.
