Product Customer Reviews

Husband has found these shorts extremely comfortable, open leg allows for breath ability and cool. No rubbing at all and all the pockets come in handy for keys and phone.
Nice shorts with a good few pockets etc to store gels, keys etc
Great pair of shorts. Very light and comfortable. The only thing I would say would be to go a size up. I’m 34” waist, got the large and they’re still quite tight.
I was looking for something to carry water, gels etc for longer runs. Water belts and the like looked bulky. These have met the brief perfectly. Kalenji's small water bottles fit front and back. Gels fit in the sides. Phones will fit in front. Zipped section for keys.They are lovely and soft, not too long and look good.
Very comfortable, fit well, useful pockets for phone keys etc, you can even stuff a soft bottle of water in the large front pocket. Ventilated.and look good. Suitable for trail running and ultras as well as day to day wear.
I have these and the ones with the compression layer. When it's hot these shorts are just the ticket with a good size waist pocket that's big enough for an iPhone 6. Keep you cool at a reasonable price.
After wearing these once they tore in to my skin at the top of each leg in a very delicate area
I've just got these today and couldn't be happier. I'm doing the London Marathon in a couple of weeks and my precious shorts have torn. Picked these up and they're almost tailor made for it. Plenty of space for gels or even water bottles and my phone fits snugly in the front pocket (there's even room for the audio jack). I've just been out for a decent run in them (90 mins) and they're spot on.
comfortable fit, not too baggy not too tight. Fantastically engineered pockets for smartphone, keys, gels etc. the pockets are positioned in the belt area so there is no uncomfortable bouncing around of the pockets' contents, while easily accessible during running.
Bought this short for my husband. I loved the material. He is a big size so I wasn't sure if that would be tight or not. Perfect. Not tight at all. Very comfortable. He loves it!
Unusual shorts
I brought these as i was after some twin skin trail shorts, and i wasn't disappointed, these have a great fit the compression short underneath hugs fantastic, the pocket system is great a nice pouch at the front to carry a soft flask or phone in, with a small zipped pocket for money or keys, a zipped pocket at the rear was also useful i was able to also put a small soft flask in there to and the to pouches where great for the 2 energy gels i was taking. A great short for when you don't want to carry a bag but want to take water. a Fantastic product with a great price
was looking for a running shorts with side for quick access like keys and cards. And back pocket to hold my phone. This was close enough to what i found and at a great price.
These shorts are comfortable, look okay, have many places to store tissues, keys, phone, etc, and not expensive.Thus excellent for trail running.
Light, comfortable including on long runs. Used for Parkruns, fell racing and long training runs on the fells. The pockets are really useful for small, light items including keys etc and the rear pocket holds all but the largest smartphone. Fit is snug but not constrictive.
