Funky Trunks Mens Training Jammer Still Black

Designed for regular training, these jammers feature flatlock stitching, a comfortable leg opening, a drawcord, and a rubber Funky Trunks logo.

Favored by swimmers and triathletes, they provide extra warmth for open water when wetsuits aren’t an option.

Made from exclusive C-Infinity fabric, a 100% Italian polyester known for its vibrant colors and excellent chlorine resistance.

This durable material outlasts typical elastane swimwear, making it perfect for frequent pool sessions, whether for fun or serious training.
