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.

Communication and delivery went well, all on schedule, one of the purchases have developed a home on a seam after only being worn once but am hopeful they will resend me some nre
very comfortable fit, would certainly recommend them
Comfortable, fit like a glove.
Delivery-good Quality-excellent Fit-perfect Value for money-outstanding Thankyou
Great quality and fit. Love the letterbox friendly larcels too.
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
Very comfortable .These had the shortest leg out of all the bamboo trunks when I looked so gave them a try within 2 days I had ordered another pack.
Very comfy.
Great quality for the money, highly recommend.

Great Product Great Price Arrived Ahead Of Time
Hubby said theyre very comfortable , feel nice and soft
Simple ordering and great delivery service
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.
Great service many thanks!
As described and quick turnaround thankyou
Perfect Thank You
Arrived on time, many thanks
