Lumberjacks wear Kevlar for protection against sharp objects such as chainsaw blades and flying wood debris. Kevlar is a strong and heat-resistant material that can help prevent injuries while working in the dangerous environment of a lumberyard.
No, Kevlar is not a hydrogen bond. Kevlar is a synthetic fiber made of a strong, heat-resistant polymer matrix. Hydrogen bonds are weak electrostatic interactions between hydrogen atoms and electronegative atoms like oxygen or nitrogen.
The two monomers that form Kevlar are 1,4-phenylenediamine and terephthaloyl chloride. These monomers undergo a condensation polymerization reaction to form the long, stiff molecular chains characteristic of Kevlar.
As "kevlar" is in fact the trademark of a type of aramid fiber, it may be capitalized (Kevlar) -- or lower-cased, as one often sees with "xerox". [see http://unterm.un.org/DGAACS/unterm.nsf/8fa942046ff7601c85256983007ca4d8/12ce03301316620685256a000007676a?OpenDocument]
Both Kevlar and boiling water can cause burns if they come into contact with skin. Kevlar can generate heat when rubbed or stressed, leading to burns, while boiling water can scald the skin upon contact.
The protective plates, depending on the age of it, will be steel, ceramics, or kevlar.

Typically kevlar is spun into ropes or fabric sheets that can be used as such or as an ingredient in composite material components. Currently, Kevlar has many applications, ranging from bicycle tires and racing sails to body armor because of its high tensile strength-to-weight ratio; by this measure it is 5 times stronger than steel on an equal weight basis. It is also used to make modern drumheads that hold up withstanding high impact. When used as a woven material, it is suitable for mooring lines and other underwater applications.
Kevlar is a fiber that is knitted or woven into a material/fabric. Those materials can be laminated to be made waterproof, but Kevlar in and of itself as a finished good is not waterproof.
