Soft Bamboo. Close, Comfortable Fit
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.

Do it once. Stock up properly.
The site was easy to order from and the prices were competitive. Delivery was good, they arrived in a recyclable letterbox box. Nice colours, a good fit and a smooth luxurious feel to them. The only downside was I didn't notice there was no keyhole access, which is my error.
Very comfortable, breathable, lightweight, nice design, soft feel, excellent to wear
Should have got the next size up but have try the xxl on and they are ok
To be honest ,since trying my purchase I appear to have developed a rash on my lower back. I am not saying this is necessarily due to my spares garments,it would be interesting to hear your comments on the matter. David Green.
Well made , fabulous quality and far superior to ones I’ve paid a lot more for .. definitely will buy again
Great comfy boxers. Love the soft feel which keep better shape on all day. Better than other makes of bamboo boxers I have used and I have tried a good number of makes.
