Our unique DualCap fill-port incorporates a 53mm inner cap that is perfect for filling your reservoir, while the 80 mm outer cap is designed for ease of cleaning and drying the bladder. The 80mm Cap includes a unique grip design that makes it easy to open and close the inner 53mm fill-cap.
TSI’s reservoir products are all produced with a Made-in-USA custom mPE/EVA film, derived from the medical industry. The film is shipped to our controlled environment cleanroom facility in Dongguan, China for die cutting, printing and welding into a complete water bladder.
TSI’s bladder film is naturally anti-microbial material that fights a variety of gram+ and gram- microbes as well as mold and fungus – Our unique formula means zero plastic taste or smell. Super tough construction results in maximum abrasion resistance.
All of our water bladder products are fully compliant with California Proposition-65, and are REACH compliant. Test reports from an independent test laboratory are available.
