SENDY is designed to get more people outside, get more people connecting with each other, the natural world, and their own true nature. SENDY is about a community. A community that helps each other get outside, get in their bodies, and feel the way nature always meant for them to feel. We don’t just want a happy planet, we want happy people too, and SENDY is the tool we can use to solve both problems. What do you have that someone else might need? Every single piece of gear that finds a new home is one less new product getting pumped out of a factory and shipped around the world. Every single piece of gear that finds a new home helps someone chase their dreams, drop into their bodies and focus on what matters. The problem is not that we don’t have enough things, it’s that those things are inefficiently distributed. We have the power to change this forever. And by We, I mean You. Every single individual reading these words. If every one of us makes sure that we let nothing go to waste, nothing sit around collecting dust and getting outdated then the problem is solved. Imagine a world in which everyone who wants to thrive in nature has what they need to do so. Imagine the generations of lives that can change if we give families the tools to return to the great outdoors.

They were founded in 1917 by Felice Sacci just outside of Milan, Italy. SILCA has been an innovator in many aspects starting by being the first company to put gauges on pumps, the first to create a high-pressure frame pump, and more recently the first to have a valve-controlled CO2 inflator. One of the newest advances from SILCA is the use of 3D Printing in Titanium.
