Bravo, and well done!

Trek Kit has it all! It's functional, durable, and lightweight with a multi-purpose driven design. I'm an avid backpacker, snowshoer, and mountain bike rider and I've been wondering where the Trek Kit has been all my life. Love at first s....ip!

awesome product

Great water storage for backpacking. Helpful if you need to wash off, too.

By Andy

great for dog owners or backpackers in general

This product is really helpful for backpacking and also when I’m out hiking with my dog. The Hydrant Tube is awesome for filling up my dog’s water bowl, and cleaning off his paws at the end of our hikes. I’d highly recommend this for camping or backpacking if you have a dog.
