SmartFunnel - Ultralight Collapsible Silicone Funnel for SmartWater Bottles

The SmartFunnel makes it easy to add protein, carb, electrolyte and other drinks powders to Smartwater bottles and other 28mm neck bottles.

We all love Smartwater bottles for ultralight backpacking, they're super light, durable and cheap and now there are a variety of more durable 28mm neck bottles. But I use a lot of drinks powders on trips to get enough calories, protein and electrolytes to fuel long, back-to-back days in the mountains and getting powders into a 28mm bottle opening is a nightmare. So after many, many iterations I made this solution.

This funnel weigh less than an ounce, stretches to fit securely over the bottle neck and is shaped to maximize the size of the opening and minimize any restrictions to the flow of the powder. Hand cast with food-grade silicone rubber from 3D printed molds, it can be squished down into a hip belt pocket and spring back shape. It is tear resistant, dishwasher safe, very very hard to break.

Also great if you use 28mm plastic bottles at home or in the gym. Keep those single use bottles out of landfill!
