Great Undies!

They’re really soft and comfy. But I also like the horizontal fly it’s very convenient.

Buying More of These, Extremely Pleased

Absolute Winner - Comfortable / cooling material, proper fit, comes with wash guide to make them last & no fuss-delivery.
I was initially a bit sceptical due to the price, but now I'll be purchasing more after having received my first batch. Well worth it

I have been trying a number of different brands for the ultimate comfort in boxers.
Sadly, they’ve been hard to find.
I am aware of the Modal fabric for its luxurious feel as I have had shirts made in the same fabric.
I jumped right in and bought 3 pairs.
They are excellent. It doesn’t feel like you’re wearing them. Unobtrusive, warm and so far, well made.
I highly recommend this product. Get on board. You won’t be disappointed.

Honestly so comfortable

Comfiest underwear, definitely going to have to start a new collection of Debriefs. Fits all your bits perfectly

Comfort and Service

Not only were these a truly luxury fit and feel, the turn around service in their first time guarantee was absolutely awesome and trouble free. Already ordered another 4 pairs.

Comfy as...

I've been wearing underwear for a lot of years. And I reckon just about every variety. Right now there seems to be a few brands competing for the comfy boxer market
Nothing is, or has been as comfy as debriefs. They last too. Clearly well made.

These Debriefs have super comfortable soft fabric, they do eliminate chafing and are supportive also , I was so pleased with the 2pairs I first ordered that I bought another 6 pairs. Thank you for bringing out such a great pair of underwear 👍🔥

Simply the best

I have tried many briefs over the years, but Debriefs are exactly what I have been looking for. Comfort and space. Feels like I'm not even wearing them.

Worth the money

These trunks are very soft and comfortable. My equipment moves well throughout the day. The pouch makes my equipment stand out which is awesome as I'm an average bloke in that way. The unique fly is surprisingly effective for access. I will stick with these from now on.

Super comfy! No complaints

These undies are some of the most comfortable I have owned and for the price I think they are well worth it. Will buy again.
