Amazing quality and lovely fit
Amazing quality and lovely fit. Super helpful and friendly, and were very quick to respond to my query!
I recently purchased this hoodie and I am more than happy with the quality of the garment I received, it is extremely well made and comfortable and looks awesome 5⭐️
Just received my hoodie and I couldn’t be happier! The quality is genuinely incredible, super soft, the right amount of thickness, and feels like it’s built to last. The fit is absolutely perfect too: comfy, and true to size. It can see it will quickly become my new favourite hoodie. Highly recommend!
The jumper is so thick and high quality, looks and feels amazing, and really comfy! It's my first time buying anything from Gymnasty, and James, the owner, is fantastic. Can't wait to buy more bits from this brand!
Got gifted these from the missus, I have the Ying set and the Nak Suu t shirt along with the deodorisers, everything is always top quality! Never an issue with fit, if I’m training I’m wearing Gym Nasty! Keep it up! And keep training!
Thank you ❤️
P.s stop buying rubbish shorts from Amazon and get Gym Nasty you will not be disappointed 💜❤️🖤
After scouting the internet I eventually found these amazing shorts! They look amazing and fit my 320lb frame perfectly! Can't recommend highly enough! No matter what size you are but particularly if you're bigger then you need these!! So happy 😊
Excellent product, I have tried a few different types of
glove glove fresheners over the years these are probably the best I've tried, quick delivery and good communications from the Gymnasty team 👍🏼
This hoodie took me by surprise I was expecting more tight fitting, thinner sport material, I was pleasantly surprised when I was told it's more premium cotton style.
Fits brilliantly, thick warm and comfy. Would have come in handy during the cold Scottish winter! ❤️
