I’m worried about that my barbell plate of 15 kilograms might pops off from the kensuyi’s shaft during workout. My barbell plate is thick and the kensui’s shaft is shorter than I thought, so the nut of kensui can tighten only by half screw. On top of that, the bolt and the nut are lighter than I expected and they are made of plastic, not metal, so their durability appears to be doubtful.

I have been planning to buy this vest for a long time. It is worth noting that it met all my expectations. Excellent vest design!

I bought many times for me and my friends. very nice for training

Uno de los mejores chalecos !
Es muy cómodo! Se ajusta excelente y es de muy buena calidad

So I'm very late in posting this review but for over a month I have been regularly using the vest following a 5x5 strength program utilising the basic calisthenics movements on top of a weighted walking / running routine. So... To summarise: My core strength is through the roof; my posture and stability have both improved tenfold; my fitness has improved dramatically and in just over 5 weeks I'm actually leaner whilst gaining strength!!! I cannot recommend this product more highly!!! There is no other out there than can accommodate comfort and progressive overload the way the EZ vest does. The clickfast mechanism makes adjusting the vest so much simpler than the previous velcro system - not to mention it's much more comfortable. Given I now have two EZ vests my wife and I have both been reaping the benefits of moving under added resistance which is fundamental for both our jobs in the emergency services! I could honestly rave about this product all day! Absolutely fantastic. On top of that the customer service and delivery times have been outstanding. My thanks to you Kensuii Fitness!! My passion for strength and fitness has never been better!!
