I purchased these shorts primarily for travelling. After purchasing way too many pairs of shorts over the years which have all turned out to be wrong in different ways (too flappy in the legs, not breathable, poor wicking, too heavy, pockets not deep enough, etc.) I'm on holiday right now, and am not ashamed to say I have worn these every day for 11 days so far (not all day every day, as have used swimming shorts, too; but as my only non-swimming shorts.)They are lightweight, yet strong; can look sporty or stylish depending on what they are teamed up with; breathable; they still smell like new; and have a stretchy waistband for post-evening meal expansion :)I understand they have been discontinued, so I am busy trying to source another couple of pairs from ... MoreI purchased these shorts primarily for travelling.

I'm not keen on super tight running shorts, these have a casual fit, they're very light, they dry quickly and they stand up to a lot of use and abuse. I have three pairs that I alternate. I live in them all summer and have for the last couple of years. For me they're an essential bit of kit.

I waited too long to buy these fearing they wouldn’t fit my Powerlifter legs/hips/butt. That was not the case. I’m 5’7” 165lbs and Medium are spot on. The amount of Stretch is significant, and they don’t hinder squatting or high stepping at all. Same fabric as Borealis jacket. These are my go to running, hiking, climbing, ANYTHING shorts. And the funky colors are awesome. Where else can I get yellow shorts that are functional?! Back pocket is great for securing keys.

These are a great pair of all-round shorts. Lightweight, stretchy, and breathable, they are very versatile. The material feels nice and they are compact and dry quickly making them great for traveling or sports. I am normally a 33" waist and size large (34") fits well and they have a handy built-in waist tightener for a snug fit. Love them for hiking or general everyday wear. I wish the hand pockets were zipped to protect valuables but otherwise, they're perfect.
Hello, I am new to your company and products and recently received my first order.Order # 5000149082. 2 momentum shorts. I ordered the shorts in a Medium because I wear a 34 inch waist which is what most manufacturers call a medium. Many mediums are 34-36 in. What I received from you were 32 in waist which do not fit. The actual shorts waist tag does not even say Medium but rather 32in. Your Website shows only S,M,L,XL,XXL, not the waist measurement in inches. I like the shorts, but do not feel I should have to pay for their return in order to get them in L which is a 34 in waist, Since I think that your advertisement was misleading to me. Are you willing to send me a postage paid sticker for my return or do you wish a new customer not to buy other items in the ... MoreHello, I am new to your company and products and recently received my first order.Order # 5000149082. 2 momentum shorts.

I love these shorts. This is my second pair. I'm a runner and I am mainly on the roads but occasionally on trails or scrub. These shorts are very well set up for much harsher wear than I can dish out. Good fabric. And they don't chafe or cause hot spots on the waist. I like the color selection and they look pretty good too (not that I'm one to dole out fashion advice). Overall, I'm quite thrilled with these
Best shorts I’ve ever had, so comfortable and lightweight. I’ve worn them for just about everything including hiking, cycling, kayaking, the pub and everyday clothing. I love them so much that I’m about to order another pair. Everything about them is so well designed and functional, from the fabric to the pockets and the drawstring waist. I’ve only had them a month, so fingers crossed that there are no issues as they age.

I wear them for everything. Running, hiking, climbing, mtn biking, swimming etc. Great sizing. I’m a thicc boi from years of powerlifting and cycling with a 29” waist. Small is a perfect fit. Accurate waist size and plenty of room around the butt and hips. Absolutely no restriction of movement due to the nature of the fabric.
Very lightweight, quick drying shorts. They fit well and have a simple but effective waist adjustment mechanism. My only criticism is that the material "swishes" as you walk making them a little noisy!Otherwise, I am pleased with the purchase.
