I don’t know what, a zipper, a button, Velcro? I put my phone in the pocket when I run and with how big phones are these days it always frustrates me that the pockets aren’t designed with that in mind. Yes the phone fits, but it sticks out and sloshes around when I run. I have start using a safety pin to close the pocket to ensure the phone won’t fall out. Maybe it won’t ever actually fall out, but it don’t trust the pockets and I hate the sloshing. Other than that the pants are fine. But I got them for the pockets so had to bump down a starI love them very comfortableI bought medium (32-34) because that’s what I usually wear. Fit perfect I like walking around in house during this hot summer. Like how it has a pocket on both sides. Makes it handy for my phone.Only drawback is that the waist line pulled over but that’s my fault I have a little bit of a tummy hahha need to cut back on beer and late night snacks but very comfortable . Sorry about the tummy pic but will give you better ideaThese shorts I use them like underwear, are tight but very comfortable, I have use them for a while now and still have the same quality, that helped me to perform better, I already ran a marathon with them. Great product.Muito bom ?This is my second orderWish they had a pee hole. Gets a little warm. Other than that I really like themPerfect for a run around town or wherever to keep as little on you as possible. Cell phone fits great as well. I have an iPhone 12 pro max.Bought these specifically to be worn underneath sports shorts to be able to carry mobile phone. Pockets work well for this purpose. Just be aware that the sizes are not UK sizes - ordered XL for a 32 inch waist and are a good fitNo complaints, I’ve always wanted a handy place to put my phone on a long walk/run and these are well priced and do the job. I’m not 10% comfortable running hard in these as my iPhone 10(I think) does bounce a little. But very happy on standard jogs. It might be an idea to close the pocket tops slightly to offer more security. I might even do it myself one day. Sitting down or working out in a gym on a bench etc, you will definitely drop your phone!Great idea but poorly executed. On my second run in these shorts, my new iPhone flew out of the pocket and bounced down the road in front of me. Thankfully I have a decent phone case! These are not compression shorts in my opinion either. I’d happily pay twice the price for better quality shorts. Put it this way, it would be cheaper than fixing a damaged phone!These are super comfy! I’ve washed them several times now and they haven’t changed.I wear them for cycling and as an extra layer under my motorcycle gear.Couldn’t be happier :) the pockets in the sides for my iPhone 11 easily, so are super handy!I got this for the purpose of having the pocket for a phone but as soon as you start running you can feel your phone bouncing around. Really annoying! Disappointed if I'm honest. I'd wear them for other activities like yoga and pilates but for running, no. Should have known it was too good to be true because it is. Spend more and get 2XU with a pocket for a real good product.
