The toughest laces out there.

How? A polymer from a Nobel Prize-winning scientist.

They’re lighter than cotton or polyester, and 15x stronger than steel, way stronger than Kevlar.

What are they made out of? 

The same material as the US army's new bulletproof helmets.

They're coated in a dry-touch wax to stay tied all day, no matter what.

They're waterproof so they can't freeze, you can get them untied at -40.

Plus they won't rot if you put your boots away soaking wet.

Some people say these are overkill, we think the other guys aren't trying hard enough.

Stronger than steel Kevlar 
These are made of 12-strand, Ultra-High Molecular Weight Polyethylene. It's 15x Stronger-than steel, way stronger than Kevlar.

Lighter than cotton 
They're as light as a feather, you won't know they're there.
