Customers praised these training shorts as "light, comfortable, breathable" with excellent stretch for squats and lunges. The quality, fit, and 3" length received consistent acclaim. Most found them perfect for gym and outdoor sports. One customer noted sizing issues, and another mentioned minor crotch ride-up. Popular for muscular builds.
- Light, comfortable, breathable, and not restricting in movement
- They keep you cool and dry throughout your workout
- The material has the right amount of stretch for squats and lunges
Very good gym shorts I have a few pairs highly recommend
Great fit and material!
Bought these shorts for my partner, super light weight
Taken sooo long to do a review coz hubby steals them straight off the washing line the moment they are washed and dried, he now has 4 pairs of this style loves the look and the feel of the material but this colour is his fav
Super comfy & light! Perfect busy on your feet at work, not just in the gym! Definitely be back for more.
Comfort meets functionality in these gym shorts! With a blend of breathable fabrics, they keep you cool and dry throughout your workout. The cut is perfect for me, and they look amazing. Also love the colour! These shorts aren't just about performance; they also score high in style. The length is perfect also.
Great shorts! Fit great 🤙
Perfect length and fit for me. Exactly what I’ve been looking for for long time. 5’9” and 165lbs
Great quality and fit. Second time purchasing these 3” the length is my preferred fit for thicker thighs
Dope shorts , good length and fit
Love them and will buy more.
Love them and will be buying more
Fits well and flexible
These shorts are incredibly comfortable and high-quality, making them my new go-to for every workout. I've gone ahead and bought 3 more colours, as they work as casual shorts as well.
Great quality shorts that fit well. True to size.
My first pair of MN shorts and I love the fit!
Love this pair of shorts. Fits well and I’m a relative small guy.
Comfortable fit and perfect length
Nice fit!
Love these shorts, so comfy
Super comfy
Great fit and pretty stretchy. Love how they look
Been looking for a good pair of training shorts and finally found them! Comfy when I’m lifting and even when sitting on the couch. Big fan!
great fitting but a little short in length
I recently bought the Streamline Training 3” Shorts in navy and had a slightly different experience than expected. There was a large hole in the right-hand pocket which I hadn’t noticed when I bought them. I wore them today and then noticed the hole when my gym key fell out. I’m a bit disappointed with my first purchase.
Obsessed with these shorts- these are my new favourite. The most comfortable training shorts I’ve ever owned, look and feel great.
Light weight, thin material and good to train in
Boyfriend loves these as his Christmas present Comfy and the pockets have zips!
My husband has worn the same style of pants as a body builder for 8 years he is now absolutely wrapped in these new shorts from muscle nation!!
Quality is just as I expected. Very thin, breathable, but strong.
Nice short, comfy feel. i should have sized down 1 personally though.
Fit perfect, durable to.
