both gi and pants are very sturdy. both are poly/cotton blend (around 50% each, give or take 5% - of the top of my head) of which i am usually am not a fan. however, in thia case i do like it for its resilience. the pants are soft yet very sturdy, and the kimono jacket is on the heavier side (fuji doesn't list the grams/m2 - it feels between 500 and 600 to me, for the jacket) with a nice rice grain weave pattern which is great for gripping and gi based holds and movement. you feel protected. the blackout theme is nice, with only black on black fuji embroidery. no other colors. almost a true black gi. next to no visual distractions. awesome gi for the money. there's not a lot of all black ones on the market, so this one stands out to me as a decent standard. i do like the heavier gi's, as it makes it feel closer to traditional judo style gi, just in the slightly more tailored and shorter bjj style. it feels dependable and utilitarian.
