The Full Story+

The blended technical fibres are high-wicking and superbly comfortable.

The Aether Boxers are so durable that no matter how often you wear them, they’ll never stretch, fade or lose their shape. Combined with elastane for freedom of movement, these boxers are soft to the touch adding comfort across a board range of activities.

In short, they’re the perfect undergarment and make a fantastic base layer for whatever life has in store for you, be it a long day in the office or something more adventurous.

Our Dynamic Moisture Control™ finish has been incorporated into the design of the boxers in order to wick moisture away, keeping you cool and comfortable throughout the day.

With flatlocked displaced seams which reduce chafing and irritation, anatomical panelling for support and a fly opening - plus an elastic waistband offers maximum comfort. 

The Aether Boxers are easy to care for, simply wash in the machine or by hand and they’ll be ready to go again in just a few hours.

We were the original lightweight revolutionaries. Back in the 1970’s we realised that cutting weight without losing performance meant that you can take less and do more. Everything we make is engineered to achieve this.

Low pack size is a benefit whether you’re packing for a day’s walking or for the trip of a lifetime. We continually scrutinise fabric specification and garment construction to minimise the packed size of our clothing. The actual pack size is tested and listed.

Fast Drying - Drying Time: 3 hours
Fast Drying - Drying Time: 3 hours

All Rohan clothing is designed to be very fast drying – as much a benefit for unexpected downpours as anything else. It’s easy to wash and often needs no ironing. Almost all garments will dry overnight, meaning you can take less with you. We test every item and list its drying time.

Dynamic Moisture Control™

DMC™ is a wicking treatment that rapidly spreads the moisture our bodies create across the surface area of a garment. This can be achieved through the technical construction of the garment or by a performance coating and ensures that the garment dries more quickly, encourages evaporative heat loss and helps you stay cooler and more comfortable for longer.

Aether Boxer's with a fly


In a previous review, I praised the Aether boxers for their support, and the lack of a fly opening was no problem for me. Now, in the new version, you keep the good support with a fly added. Everyone should be happy now! I remember the horrible artificial fibres of my youth and I am still amazed that Aether boxers do not get stinky after several days of wear. This is a great advantage when travelling.

Bring back the cool silver trunks


Similar to an earlier review I unwittingly bought a couple of pairs of the version with the no fly zone. I then saw and bought one replacement pair with fly. I find the Aether Boxers are a tight fit, which need to be adjusted for comfort when putting them on. I think they are OK for physical activities and I’m sure some folk will think they’re brilliant. However, I much prefer the fit, functionality and versatility of the Cool Silver Trunks. They’re the only underpants you’ll need for formal, informal and action wear. Please bring them back into the Rohan range.

Thank you for your feedback. Our Design Team did review and research the underwear we were offering in our range in 2019. Throughout the development of this, they did come to the conclusion that when hiking or trekking for prolonged periods of time, the most important thing was support and comfort. The Aether Boxers are highwicking and feature flatlocked seams which help to reduce chafing so we hope you will find these comfortable during both everyday use and during intense activities.

They seem to do their job well


I had bought a set of the non-fly version in a previous sale. Tried ( and kept of course ) one pair but sent the rest back.

I have just bought another set - this time with the fly while they were discounted.

Quite comfortable and absolutely ideal for taking on holidays and in our camper van because they are so easy to rinse and they do dry overnight. I usually wear loose fit cotton jersey boxers but these are heavier and can take days ( up to 3 days in my experience ) to dry out so not really practical.

Since these are a close fit, I would have preferred a trunk with the shorter leg but Rohan seem not to have any at the moment, I did source some Rohan silver ultra trunks from a seller with old stock and these are superb.

Please bring these back Rohan.

So I'm on a trek, and I've got many layers on. And a belt and a rucksack belt. And my comfy Aether boxers. But nature calls. Up, over, belt in the way, hit T shirt, backtrack, down under - no, not that way. The trouble with the Aether's is the leg is long - too long - halfway down my leg - so don't go that way. Getting panicky now. Wait a gosh-darn minute - these are the new Aethers - in and out of the fly. Job done. Phew. And, being Aethers, these don't get sweaty-itchy like the completely plastic ones do, too.

Thanks for your feedback, glad it all worked out ok in the end!

What a Dissapointment


Rohan at its best they do away with fantastic trunks and replace them at first without a fly version then hurry through another version with a fly which these trunks have as an improvement on their previous trunks, boy did they get it wrong with this offering. Material is poor and cheap looking and feel and the fit is just awful, why do they always try to reinvent the wheel when they already have a great product.

Thank you for your feedback. We have had many mixed reviews regarding having a fly opening and not having one. All customer feedback is passed onto our design team due to this we have re-introduced a fly version. The material is soft and designed to be comfortable, sorry to hear that you do not like them, your feedback will be passed on.

Men’s Aether Boxers (with fly)


Superb comfort, material and fit. I have had Rohan underwear in the past but stopped buying when they stopped the fly opening version! All I need now is a White version (please!) to wear under light coloured trousers in the summer!

Dear Dennis, I was glad to read you have been pleased with your Aether Boxers. Your feedback with regards to colours have been passed on to the Design Team.
