Mammut Aenergy 12 Backpack

12 L at 280 g: a speed-hiking pack that carries only what you need, lightly

This is a 12 L, 280 g backpack that puts an emphasis on light weight. It works for speed hiking, which means walking in the mountains at a fast pace, as well as for everyday outings. The large outer mesh pocket and two chest pockets let you keep essentials such as trail snacks separate.

Features

• The capacity is 12 L and it weighs 280 g. Actual dimensions are about 21 cm wide, 44 cm high, and 10 cm deep.
• The wide shoulder straps use a material that lets air through easily, and the back pad is designed to be less bulky.
• The main compartment is compatible with a hydration bladder (a bag for carrying drinking water). On the outside there is one large mesh pocket.
• There are two drop-in chest pockets (the type you slide items into from above), which hold essentials such as energy bars.
• It has a PFC-free (perfluorinated chemicals) durable water repellent (DWR) finish and is made mainly from recycled materials. Reflective material is also used in the details.

Recommended for

• Those who want to pare down their gear and walk light and fast
• Those looking for a small pack that works for both hiking and everyday outings
• Those who want to walk with a hydration bladder (a bag for carrying drinking water)

Pros and things to consider

Pros

• There is reflective material in the details, and the fabric is made mainly from recycled materials.
• It is compatible with a hydration bladder (a bag for carrying drinking water), so you can take in fluids while walking.

Things to consider

• At 12 L, it is not enough for overnight mountain trips or days with a lot to carry.
• No rain cover is included, so you need separate preparation for rainy days.
• The pockets are mainly one mesh pocket and two chest pockets, which may feel limiting if you want to sort your items into finer categories.
