Best fitting Lulu underwear yet. I really like these boxers! The fit is great, there is virtually no ride up and there is support in all the right areas, if I had to pick a negative its that they are a bit warm so being from the south I don't get to wear these awesome underwear as often as I'd like. If you guys can lock into the things you did right with these guys I think you're onto something as far as creating great men's underwear. Though I am partial to having a front opening in my underwear I don't think any of your offerings have that. October 27, 2014
I wanted to love them... I bought these about a week ago and loved them. My favorite features where the fit. Unlike other compression shorts, there isn't the same amount of compression throughout the short. In the crotch area, it is the lightest so your junk isn't smashed. In the bottom leg, it is the tightest so the shorts don't ride up. However, I did find fault in the length; they are a little long at a 9 inch inseam, 6 would've been better. Onto the bad news now. Since the time of purchase, I've only worn them once [and this was to bed]. When I awoke, I was dissatisfied to find that there were two long seams that had fallen apart. Both of these threads were from the area where the crotch panel (the striped material) meets the normal material. I understand that clothes are not invincible, but these shouldn't be falling apart after only a few hours of non-reponsive sleep. October 26, 2014
I like them, but there's room for improvement. Well it's true what they say, the threads will come loose, however since it's only day one wearing them I hope no more come loose :) Though I do have to say that also my other ones have threads that come loose too, but they don't fall apart. One other thing I was a little dissatisfied with was the fact of me being so tall that these don't sit where I would like them to, it would be nice if they made them in two different sizes. Otherwise I'm very happy with the purchase, they are comfortable and feel nice. October 22, 2014
Quality compression shorts These shorts offer superb performance for running, the gym, yoga, or any form of exercise. The seams are smooth and do not chafe (hence the "chafe-resistant flat seems"), contrary to some reviews, and the luxtreme, Silverescent fabric is what sets these apart from other compression shorts. I've had Under Armor shorts before, but the nylon Luxtreme fabric and durable construction of these Lulu's outweigh their cheaper polyester counterpart. Make sure to consider the 9" length if you have shorter legs. My final thought: I will be purchasing more. September 25, 2014
My Favorite I was only able to buy one pair before I was told these are not going to be manufactured anymore. These are the only pair that doesn't ride up on your thighs whenever you're you wear them. PLEASE PLEASE bring them back!!! September 10, 2014
Who designed these!? Great if you have a disproportionate body/ridiculous long legs. The inseam is crazy long. If I slide the thigh up they bunch and/or slide back down with movement. Based on their sizing charts and help from the educators.. the boxers don't fit right. Or they dont need to be that long. ALSO if a guy designed these.. there would be a very key feature. Just like every other guy's boxers, these don't have a fly! How am I supposed to urinate? July 15, 2014
Don't Waste Your Money My biggest problem with these boxers is the seam that they have going straight down the middle of your dick. Oh, and the other seam that intersect with that seam right on your balls. The seam is not taped, its is just a rough seam on the inside guaranteed to cause friction and rub you in a way that will be uncomfortable. For a really expensive set of compression shorts they did a poor job with the design. It is too bad, I had high hopes. Now I am just out the $38. June 30, 2014
Inconsistent fit I bought myself a $38 pair of boxers to try seeing all my shorts from Lulu are super comfy...they fit great and like them very much so I asked for a pair of blue ones for my birthday from the wifey. But these ones don't fit the same at all...too tight around the thighs and too loose around the waist band and as soon as I start walking down they come. First pair I love wearing....the second pair I can't stand them...final sale...darn!!! May 26, 2014
Everything is good except the "flat" seams... My first purchase from Lululemon are these boxers. After seeing many friends, people with the brand I thought I'd give it a shot. They feel wonderful I've never had something so comfortable, the fabric is very nice. Sadly I'm experiencing the same thing many others are seeing... The seams outer edge is starting to loosen and threads are now hanging off. This happened to me the same day I bought them, I got home wore them around the house, then slept in them the same night. The following morning the outer seam on the inner thigh already started to rip and loosen off. This is after at most 10 hours of wear time, not even running or wearing them for a full day. I am quite disappointed since I expected a premium product at this high price point. I just can't get past the actual product... I didn't mind paying a premium since I thought the product would be durable as well. Now because of Lululemon's return policy, I can't do anything about them. I've given the brand a shot, and a bad first experience is kind of turning me away... May 12, 2014
BEST Boxers EVER!!! These are the BEST Boxers EVER, period. I like a bit of a longer leg on my boxer briefs to wear under shorts. These are perfect length and they have just the right amount of compression. I am an UltraRunner and have worn these for many 50K, 50 Mile, and even 100 mile races. These boxers are the BEST and I have never had any issues. They vent incredibly and hold everything in place just right. I am 5'-11" and 155 lbs, athletic build with muscular thighs and they fit perfect. The fabric is awesome and stretches just right. If you like Nike Pro Combat or Under Armour you will use them to wax your car now and buy a whole fleet of these babies. Trust me, you will love them. May 5, 2014
