Repel Resistance Bands are made from 100% Latex.

Each Medium Band is 1" wide, 4.5mm thick, and 20" long,

These can be used for exercises involving the lower body, calves, quads, hamstrings and glutes. They are also ideal for stretching exercises.

The bands are 20" long, making them ideal for setting up, no need to double them over like you have to with the 41" bands most retailers sell.

For Bench Pressing:

A pair of Medium Bands adds 10-15kg in total to the bottom of the bench press and 30-35kg at the top (depending on arm length and bench height). This gives a load contrast (the difference between top and bottom) of 20kg.
