Made from ultra-soft bamboo, these trunks are designed to sit closer to the body for a secure, supportive feel. Breathable, moisture-wicking fabric helps keep you cool, dry and fresh all day.
Supportive and Smooth
The fitted shape stays in place without riding up, while a soft, brushed waistband keeps things comfortable without digging in.
Flat, printed care labels remove irritation completely — so nothing rubs or gets in the way.

No chaifing very soft and well made
These trunks arrived promptly, are beautifully soft easy to wash and keep their shape after many washes. I’d recommend them. My husband says they are very comfortable to wear.
Excellent product. I was also very happy with the.boxed sets of their socks that I bought for gifts last Christmas
I have brought a few things recently and they are all great i would definitely recommend these products, and the service is excellent well done
The boxers are a good fit and are very comfortable. I found that they ride up a little but not a huge issue. However, after only one wear and wash, one pair has developed a hole. These boxers are also sold on Amazon and I should have read the reviews there first because there appear to be widespread quality issues.
Excellent quality and price backed up with v speedy delivery.
Fast delivery super comfortable
