Business graduate Sandra Seilz decided to invent the trousers after she was attacked by three drunk men when she was jogging in the woods.
Women’s intimate areas will be sealed off with a “protective shield”.
The website says: “Get into your safe shorts, pull the ergonomically placed high-tech cords that are tear and cut-resistant until the trousers are in place.
“Should someone try to get into the trousers of the jogger the alarm will go off at a volume of 130 decibels, which is supposed to scare off the attacker.”
The trousers are made of the same material as bullet-proof vests and can only be cut by attackers.
Ms Seilz said: “Safe Shorts provide triple protection against sexual assaults, and we’re very proud of them.”
The shorts can be purchased online for €149 on the website www.safeshorts.eu and the businesswomen hopes to also make lockable pants for going out.
