Whether you’re backpacking, bikepacking, or just need reliable tape for on-the-go fixes, Ultra TNT Repair + Seal Seam Tape is the perfect “go to.” Add it to your UL repair kit and know you can fix anything, even deer v. car trim mishaps!

FEATURES

• High-tack, strong adhesive comparable to the best permanent DCF bonding adhesives and high-quality duct tapes.
• Ultra threads reinforce the tape at 0°, 45°, 135°, and 180° angles, preventing creep and stretch.
• Can be used in place of duct tape for most applications, offering far greater strength due to the Ultra (Dyneema/Spectra) reinforcement threads.
• It has replaced regular duct tape in my on-trail, bikepacking, and travel repair kit. I’ve even used it for deer vs. car body trim repair.
• Repairs broken trekking and tent poles far more effectively than duct tape.
• Ideal for repairs and reinforcements on DCF shelters.

INCLUDES

• ONE: 1.25″ x 8′ piece of Ultra TNT Repair + Seal Seam Tape.
