An 18 L backpack for everyday use, with a detachable mesh pocket
Mammut's Alto 18 is an 18 L backpack suited to commuting and light day hikes. The fabric is ripstop with a water-repellent finish, and a detachable mesh pocket is attached to the front. The design was inspired by Mammut's mountaineering backpacks.
Features
- Capacity is 18 L. Actual measurements are about 30 cm wide, 46 cm high, and 8 cm deep.
- The fabric is ripstop (a weave with reinforcing threads that helps keep tears from spreading).
- It has a PFC-free (perfluorinated chemicals) durable water repellent (DWR) finish.
- The mesh pocket on the front can be detached, and there is a bottle holder on the side.
- It uses recycled materials and carries the bluesign PRODUCT label, which reflects consideration for the environment and safety, along with the Fair Wear label.
Recommended for
- Those who are looking for a backpack in the 18 L class for commuting to work or school and city walks
- Those who want a pack that can double for light day hikes
- Those who want to carry small items separately in the front mesh pocket
Pros and things to consider
Pros
- The water-repellent ripstop fabric suits outings on days with light rain.
- The mesh pocket is detachable, so on days you do not need it, you can take it off and keep the pack streamlined.
- With a slim depth of about 8 cm, it is designed to be less bulky when worn.
Things to consider
- At 18 L, the capacity is not enough for overnight mountain trips or days when you carry a lot.
- The fabric is water-repellent, so in heavy or prolonged rain the contents may get wet.
- At about 8 cm, the depth is slim, so thick items may be hard to fit.
