Flex-metal® Additional Weight Kit
      Contains 10 – ½ pound weights
Flex-metal® Additional Weight Kit   
includes 10 patented IRONWEAR®
Flex-metal® weight inserts. These unique weights 
flex and move with you when you exercise. They 
are as soft as your own skin and act as padding 
to protect you in case of a fall. Flex-metal® weights are 
the most comfortable and safest weights available.
Flex-metal® patented weight inserts are super 
flexible, thin and flat. All the edges are fully rounded,
so there are no sharp or hard corners or bulges. 
Each individual weight insert has a fabric shell to 
allow it slide into the weight pockets.
Flex-metal® patented weight inserts are much 
safer than any other weights and do not push into 
your body. Metal bars can be extremely dangerous
if you fall and they move around during exercise.
Metal bars also block your movement and can not be 
used comfortably for floor exercises. Shot and sand bags 
although less dangerous move around and bulge out 
causing localized high pressure areas which can chafe
and bruise, and are also not suitable for floor exercises.
Flex-metal® patented weight inserts are only ½ inch 
thick, 2 inches wide and  4 ½ inches long. The inserts fit 
into the patented internal stretch pockets of many of 
IRONWEAR®’s products including the Uni-Vest™, 
Uni-Pants™, Under Vest™, Cool Vest™, Hand Irons™, 
Ankle Irons™, Shoe Irons™ and Iron Belt™. Most 
IRONWEAR® products are supplied with one weight 
per pocket, but the pockets have been specially designed 
to hold one or two weights securely.
Flex-metal® Additional Weight Kits make it possible to double the 
weight of most IRONWEAR® products. Here is a chart which 
explains how many additional weights can be added to
