Sustainable Underwear, Natural, Comfortable Performance Underwear for Men

Our sustainable underwear is natural, comfortable performance underwear "Tree Trunks" are made with Tencel Modal, a soft CO2-neutral fabric produced from beech trees grown in sustainable European forests.

We can’t promise that you’ll always produce a personal best whilst wearing our Tree Trunk underwear. But with all seams placed away from potential rubbing points, plus a knitted and elasticated waistband that sports a brushed lining, we’re confident that our beech shorties will be the most comfortable underwear you’ve ever worn.

Designed for SueMe by the same person that Ian Thorpe’s Olympic gold medal winning swimsuit, Tree Trunks feel like you’re wearing nothing at all. We are so proud that our underwear garments have been developed and designed by the ex-Head of Global Innovation at Adidas James Lamont. He's best known for creating superlative go-faster fabrics for elite cyclists, competitive skiers and performance swimmers (Ian Thorpe wore one of James’ designs when he won an Olympic gold medal).

Fun fact: the biodegradable and compostable beech tree fibres used in Beech Shorties will ultimately return to nature (although not while you’re wearing them). Remember, all products are delivered free to mainland UK nationwide. Join us today! 

Noted ultra runner, renaissance adventurer and New Colorado 14ers Record holder Joe Grant "I've been using Sueme Tree Trunks for the past 3 years, for a wide range of activities, including biking, skiing, running, climbing, and casual wear. The trunks are extremely comfortable, durable and perform perfectly for all my adventures.

All products are so comfortable that you forget that you are wearing them..As a motorcyclist you can wear them for a few days before they need washing which is helpful when touring.

My favourite pants!

I think this is my fifth or sixth time buying the black shorties 3-pack in about a decade: ever since discovering them as a newbie hiker, I haven't wanted to wear any other pants! Whether for physical activity or just everyday comfort, what I love about them is how soft they are and (without being too graphic!) how they can be worn as high and snug or low and relaxed as you like, thanks to their gentle but robust elasticity. Plus, for any other cloth pad wearers out there, you can totally count on these pants to hold them in place perfectly. Lastly, shout out to their durability: expect to wear them until they're all but threadbare. In short(ies), these are a longterm fave that I don't expect to switch from and feel really good about the sustainability factor of too.

Great for working outdoors

Have worn these for over 10 years and they are brilliant if you spend most of your time as I do working in the outdoors ie heavy gardening and conservation work as well as walking activities

High quality long lasting product.

Over 3 years ago I had a nasty bout of shingles that left the skin permanently sore on my right hip, I am not looking for sympathy, it is what it is. My point is this, I can only wear these boxers because normal women's underwear is too scratchy so for 3.5 years I have washed and worn the same six pairs of Sue Me boxers and they are still like new. The fabric has got a bit softer with washing which nice but they are in perfect condition which I personally think is impressive. Definitely good value.
