Our take on a mid-waist fitted trunk. Made from Global Organic Trading Standards-certified organic cotton, we add just a touch of elastane for stretch. We only use the finest cotton yarns to knit the fabric for our classic trunks. It's why they're so soft and long lasting, retaining both shape and colour for wash after wash. All our trunks are made in an eco-friendly Portugal factory that uses electricity from renewable sources.

Our trunks are just like every other product we make.
They're built to last. For years.
The fabric is made of fine, extra-long organic cotton fibres. It's very soft and incredibly hard-wearing.
The elastic waistband is also of exceptional quality.
It can be pulled and mishandled and washed again and again, but it will keep its elasticity and a certain softness of touch.
Every stitching on our trunks is made by hand and with a lot of time and care.
That prevents threads from unravelling and seams splitting. Everything stays beautifully soft, but it's also seriously solid and super strong.
So buy our trunks and get ready for a long-term relationship. Because they'll still be there when all your other purchases have come and gone.
Guaranteed.
Was looking online for organic cotton underwear saw these thought hmm so placed my order. Really happy with the fit the colors and styling. Going from boxer briefs to briefs was an adjustment but I’m getting to prefer them honestly because there’s nothing to bunch up on my thighs
Thank you very much Ronald! :)
Bluebuck’s underwear is exceptional. The high-quality organic cotton ensures a soft and comfortable feel, while the durable construction promises longevity. Their commitment to sustainability, with production in Europe using 100% renewable energy, is commendable. The designs are both stylish and practical, offering a perfect fit. Overall, Bluebuck delivers outstanding products that align with eco-friendly values.
Thank you so much Arshan for you great review, that means a lot to us! Have a great day
I like how smooth the material is and have bought this striped t-shirt three times
Thank you Eugene for your review and thank you for your custom!
Great quality, great design and just like Blackpool Tower, impressive ballroom.
Thank you Russell :)
I found this brand at a store in Portland, OR and after one pair I had to get more. They are incredibly comfortable and breathable with plenty of room. Will be buying more! For sizing, I normally wear a US Medium in briefs and went with the Large here and they are a perfect fit.
