Tantrums 2
At Tantrums, we believe endurance sports like trail running are as much a mental challenge as they are physical. It’s not just about stronger legs or better lungs—it’s about silencing doubt, pushing through the tough moments, and persevering when your mind says stop.
Founded in Pasadena, California, Tantrums was born on the local trails that shaped our training and love for the sport. We design hydration packs and performance gear for trail runners and endurance athletes who know that doing hard things starts way before the start line. The daily sacrifice paid in pre-dawn miles and sweat. Our products are built to perform at the highest level—no gimmicks, no distractions, no unnecessary features—just gear that feels like an extension of you.
We don’t make equipment that just “works.” We make gear that gives you an edge. When you’re deep in the pain cave and the voice in your head says to stop, you need gear that won’t let you down.
Get out of your head.
