The Kalenji running briefs are the most comfortable underwear I have ever found. They are perfect for traveling as the can be quickly washed in a sink and the they quickly dry. I've also dried mine in the dryer without a problem. However don't use a hair dryer on high as I have burnt holes in them. I have bought about 10 pair of these and used them as my go to daily underwear. I highly recommend them. I have two recommendations. The color isn't the best to wear on a hot date. Could we get some different colors? A hot red or blue perhaps? Secondly, it seem that certain sizes are very hard to get and are out of stock. Presently large is unavailable. Could you guys improve your stock of my go to undies?
I purchased the briefs and the boxers of the same material. I've worn them as daily wear for over 6 months (not the same two pair SHEESH!) and took them with me on a recent bike tour. they dried fast, took up little space and are very lighweight. All great attributes for cycling gear. My one and only disappointment came when I inadvertedly tossed a pair in the dryer and they melted! (MY BAD!) I find both styles are comfortable, offer good (not great) support and are easy to care for. Just remember to READ THE CARE INSTRUCTIONS!
Our slim 14-year old athletic son loves wearing these briefs swim practice. He says they feel way better to wear than jammers.
Our slim 14-year old athletic son loves wearing short tights for cross country practice. He says they feel way better than wearing shorts. Size small fits well. He is very happy.
Our slim 14-year old athletic son loves wearing these briefs for swim practice. He says wearing them feels way better than jammers so much so that he had me purchase four to wear almost every day at practice. Size small fits well. He is very happy. Seems like most boys are wearing speedo briefs again.
Our slim 14-year old athletic son loves wearing these briefs for cross country or track under his shorts or short tights. He says they feel way better than boxer briefs or regular tighty whities so much so that he had me purchase a dozen for him to wear almost every day. Size small fits well. He is very happy.
Great for running. Better than any other brand purchased previously
Very breathable and comfortable.
Great product
Went for a run in 35c heat and these were perfect for the conditions.
Bought these to go running in. Very comfortable to wear.
I have several pairs of these briefs. They are very comfotable and ultra light. The pouch is supportive both in gentle and strong exercise. Most of all the pouch is single layer, which is much more responsive to form, and much cooler than other briefs. In the past I have had to cut the inner layer out of briefs to get a comfortable and supportive fit without undue heat build up. These can be worn under unlined high cut running shorts with great comfort and look great, and also make excellent general purpose underwear and loungewear. The sizing is forgiving. I fall between sizes and so I have two sizes which each fit well, with the smaller size accomodating me well if a little more snugly. Both colour fabrics have a good feel with the grey perhaps somewhat better. The red fabric is less opaque but still covers well except very close up. They are much admired in the locker room.
Love these for running or with bathing suits.

Purchased these this week. Seem good. Hopefully they will last a couple of years, but don't know yet how long anything from Decathlon may last.
