Yep, over twenty gis. (And that's just how many I have right now, obviously. I have no idea how many more I've owned over time.)
The two most common questions I get-- why, and which one is best.
Why is easy: I train 6-7 days a week, often twice a day. When I was back home in Austin at Relson's and then Humaita, sometimes it was three times a day. You can't just have four or five gis... you'll wear them out, even if (like me) you can machine-dry them without worrying about shrinking. (I prefer to shrink my gis because usually I'm an A0, sometimes an A1.)
Edited to add: for fit evaluation, just know that I am short (5'2") and fat (too much to fight leve/lightweight) and my shape tends towards pear with junk in the trunk.
The gis I have:
Mizuno Rickson model (vintage)(size 3.5)
Black Eagle Predator (men's fit) x3 (A1)
Black Eagle Predadora (ladies' fit) x3 (F3)
Black Eagle Raptora (F3)
Atama ladies' fit (F3)
M Kimono (vintage) (A1)
Scramble Sengoku (A1)
Moya Hawaii (got it used, I wouldn't buy a Moya new and in fact I want to sell this one as wearing it embarrasses me because of this.) (A1)
Fenom x2 (one is A1/A2, the other is A1/A1C, jacket/pants)
Maeda Conde Koma (A0)
Datsusara hemp x2 (A1)
Kauai Kimonos ripstop x3 (A0)
Vulkan Pro Light ladies' fit (F3)
Vulkan Ultra Light mens' fit (A0)
Vulkan Ultra Light ladies' fit (F3)
Aesthetic Whiteout (A0)
Lucky (the original Lovato version) (A1)
I've semi-recently also had DFKC and BJJ Globetrotters gis.
There is NO ONE BEST GI. Sorry.
Coolest for collector/rarity reasons: Mizuno Rickson
Most comfortable material: Datsusara hemp
Lightest/best for hot weather training and travel: Kauai
Best fitting pants for smaller waist, bigger butt/hips/thighs: tie between Predadora, Fenom slim cut but curvy (half size between one and the next), Fenom classic cut
Best heavy jacket/hard to grip lapel: tie between old (no longer made) Ouano and Scramble Sengoku
Best light gi for competition: cross between no longer made, limited edition Predadora, the Aesthetic Whiteout, and Vulkan Ultra Light (either fit)
Best gi for cool colorway/embroidery/interior lining: tough call, some worthy options are the Aesthetic Whiteout, Competidor white with pink flower (no longer made), Maeda Conde Koma, DFKC (2014 womens' competitor, white or black), Scramble Sengoku, Fenom white with dark magenta embroidery.
There you go, my humble opinion, as of now. :)
