Very Hard To Submit (VHTS) is a company founded in 2012 making jiu-jitsu kimono and MMA wear. Per the manufacturer: "[The gi] base fabric is 550g pearl weave fabric for the jacket and ripstop single weave fabric [for the pants]. Its clean and high end design with detailed patches [unique to the gi]. It is appropriate for this humid and hot weather."
My experience with VHTS has been overwhelmingly positive. I was contacted by VHTS who mailed me a kimono that arrived within 2 days. The kimono is a clean and very simple design with a sedate black VHTS logo on the shoulder. There are gray and black accents along the lapel, the skirt "V" on the flanks is also reinforced with black accents. As a pearl weave it is soft and light but with surprisingly robust, medium thickness collar, with a well rounded edge not often found on a kimono this light. This top ranks well within the top three that I have used.
The pants are the best kimono pants I have tested. They are ripstop fabric with a reinforced crotch of kimono material. The waist tie is a thick but soft rope that stays tied without getting so knotted that it cannot be opened. The knee area is reinforced. There is a small box-like smiley face on one hip.
Based on my review of the IBJJF rules, I believe this gi is legal. For the current low price this is an excellent investment for anyone in the market for a kimono.
The only negative is that the A-4 cut is more generous than most other kimono that I have used.
