Tried them out today during my squat session and I really like them. Had no problem going ATG as they didn't restrict my mobility at all. The material is very light and breathable, but surprisingly nice and warm, so prefect for the cold weather. They taper very nicely around the quads just like in the photos, so there's plenty of room if you have big legs. I also like the zips on around the hem - they're a nice touch. You can adjust the tightness to fit snugly above your shoes if they're a bit long for you, or roll them up if you're wearing knee wraps etc.
I'm average height and about 90 KG, and I got an M and L size as I was unsure which would be best but I personally like the large size more as there's a little bit more room around the thigh area so the fabric doesn't rub together which can wear it down.
Looking forward to seeing what else Gabriel will put out in future. Hope you keep making more good quality weightlifting clothes like these as I'll definitely buy again!
