Tips & Advice

Our ultralight backpacks allow you to reduce the weight on your shoulders while bringing the necessary equipment. It is important to choose your backpack carefully according to the size of your bust and your size.

At Mount Trail, our philosophy is to offer backpacks minimalist and tailored . We focus our design on all the features necessary for long hikes, day hikes, thru-hikes or any other outdoor activity. We are fans of ultralight and minimalist backpacks. The design of our bags was created to meet your needs, while making them very versatile.

Our research philosophy of ultra lightness is not limited to your backpack. You can intelligently minimize the weight of your backpack carrying only what is necessary. The heaviest items (excluding water and food) are the backpack itself, the tent and the sleeping bag. Weight is an important element to take into account. Minimizing the weight of your backpack does not mean reducing your comfort. On the contrary !
