The Start of 4Monster
Aug. 2015
It all started on a camping trip to Yellowstone National Park. While four senior outdoor enthusiasts get together，the conversation took an unexpected turn to the subject of outdoor gears. Our designer friend brought an awesome travel backpack. We agreed that it was very beautiful and functional, but when asked about the cost,USD 199 surprised everyone. A question came to our minds: Why don’t we make some practical, stylish and lightweight outdoor gear? After camping, our trip leads us to Big Sky City in Montana. Lying under the starry sky, we decided to build a functional and stylish outdoor brand.
Sep. 2016
We started with quick-drying towels and backpacks. In this year, we did various design draft and material testings. After many twist and turns, we finally resolve the basic prototypes of our original towels and backpacks. We received a lot of valuable feedback from many outdoor enthusiasts which we would like to thank to.
Feb.2017
4monster was born, based on technical materials, and with the latest design, we are committed to creating a “portable” outdoor products brand, with minimizing size, but also aesthetic, durable, practical and fashion.
