Female joggers in the Big Apple are fighting fear — with their bras

New Yorkers are snapping up sports bras made with a secret pocket that holds a knife or pepper spray in the wake of a beautiful jogger’s murder in Queens, the firm’s founder said Monday.

Sales of Booby Trap Bras, which feature a pocket sewn into the lining, have spiked 80 percent after Karina Vetrano’s tragic death in Howard Beach last week, said Texas-based bra developer Jennifer Cutrona.

“Sales are blowing up,” Cutrona, 36, of Cedar Park told The Post.

“I keep getting orders from New Yorkers, pinging my phone. At first I was thinking, ‘What’s going on?’ Then I read the story about her. And I got sick to my stomach,” she said.

Cutrona was inspired to create the weapon-hiding bra last year after she herself was attacked while jogging, she said.

“I was nearly jumped when I was running on a trail. There was a guy lurking in bushes. He tried to grab my arm — but he misjudged and I got away. He yelled at me as I ran away. It really jolted my perspective,” she said.

“I was like, ‘Oh my God. This really happens.’ Once the fear wore off, it was anger. So I sewed a knife sheet in my bra and then I wasn’t scared to go back and run on the same trail,” she said.

The goal of the no-fear brassiere, which costs $54.99, is to make female joggers feel empowered, she said.

Cutrona is also partnering with Mace pepper spray to launch a sports bra with a built-in button to call 911, she said. It will likely hit the shelves in December, she said.

“We want women to get out there, stay safe and stay active. And never let anyone bully you off your favorite trail,” she said.

Last week, 30-year-old Vetrano left her home for a solo workout and never came back. She may have been sexually assaulted before she was brutally killed, cops have said.

In the past week, New Yorkers have purchased the bra more than customers from any other state, Cutrona said. One customer was the mother of a jogger who lives less than a mile away from Vetrano’s home in Queens, she said.

“She had mapped out how far her daughter’s apartment was from the crime scene. There have been some really heartfelt calls,” she said.

Some customers were men worried about the women in their lives who jog outdoors, she said.

Cutrona also offers literature about knife use because knives can be turned against women who don’t hold and handle them properly, she said.

“I recommend practicing 50 times before you take [the knife] out with you. Our whole marketing campaign is you don’t have to be afraid,” she said.

Booby Trap Bras are sold with a 3-inch knife and case, which snaps into the lining of the bra, for $12.99. It can also be bought with Mace pepper spray for $16.99.
