Stay Hydrated While On The Hunt

Nosler, Inc. is proud to announce a partnership with Grayl®, the leader in innovative water purifiers and filters, to bring the world’s first titanium water filter and purifier bottle. With design and engineering input from trusted hunting and backcountry professionals, the 16.9 Fl Oz UltraPress® Titanium Bottle delivers unparalleled strength-to-weight ratio, long-lasting durability, and multifunctionality not found in other water filter bottles. Like all Grayl purifiers, it utilizes Grayl’s patented press-to-purify technology to remove all global waterborne pathogens (virus, bacteria, protozoa) and filter out heavy metals and chemicals, including lead and PFAS.

Behold the most versatile water purifier ever dreamt, let alone built! The world's first titanium filter bottle provides unparalleled strength to weight ratio and meets the most challenging rigors of the outdoors. It’s drink-mix ready (hello electrolytes) and the Outer Ti Cup can be used to heat water and cook food near a fire or on a camp stove. The .5L UltraPress® Titanium Water Filter & Purifier Bottle provides complete global protection from virus, protozoa, bacteria, particulates, chemicals, pesticides, herbicides and heavy metals.

 “We’ve been testing the Grayl filter systems for numerous years and use them for most of our hunts. They not only work great for quickly filtering water while on the go but they also have a very minimal footprint and weigh almost nothing,” - John Nosler, President of Nosler “The ability to also use it to cook with, along with the strength of titanium, it really is an essential lightweight tool for going out in the field further, for longer periods of time.”

“Titanium is amazing— tough, lightweight, fire safe, and accommodates welds,” - Travis Merrigan, Co-Founder and VP of Product for Grayl. “Our challenge was to utilize Titanium’s unique characteristics in the most useful piece of equipment you carry in your pack. We believe we’ve done that and we’re incredibly proud of the UltraPress Ti and all it has to offer.”
