Why We Like The Lithium 15L Daypack

Whether we're trail running, climbing, or just out for a brisk stroll in the mountains, the Mammut Lithium 15L Backpack helps us shift into a higher gear with a speedier, lighter weight design. The well-ventilated back panel keeps us cool and comfortable while we're trail running, and the integrated, detachable raincover protects our gear in a pinch under passing rainstorms. A zippered main compartment and large front pocket accommodate everything we need for an afternoon at the crag, while side compression straps and a hydration compatible design help us adapt on long, roaming day hikes.

Good day pack

Good smaller pack for day hikes or weekend trips out of town. I do like the phone pocket for hikes as mentioned previously. I like being able to pull the waist strap out for use when flying or throwing in the car for overnight.

Excellent size and features for the price

The backpack has great pockets, a comfortable attachment system, built in raincover, and hip pockets. It is hard to find all of these features in a backpack this size.

Good Smaller Pack

Familiarity:
I've used it several times
Size Bought:
15L

It is a decent little pack. I purchased this for a 50Mile ruck that I will be doing late summer. It may be a little to small for my needs for that particular journey. It fits a 3L camelback well but when full, there is not a ton of room for other needs (additional shoes and larger clunkier items). Lots of little pockets and storage. Fits comfortably on the back and breathes fairly well. I think this bag is ideal for shorter jaunts and perfect for long cycling rides.

Perfect little all-rounder

For years I used my Black Diamond BBEE as a small go along bag, but after 10+ years of abuse it started tearing. The search for other substitutes was attempted, but not seemed to fit the bill until I got the Lithium 15. A little larger than the BBEE, it also does well on work trips where I'm in and out of boats, riding ATVs, and wading small creeks in the same day. A common companion for winter fat bike rides, and long lift assisted winter pow days where I wanted an extra set of gloves, water bottle, and a sandwich for the afternoon. The built in rain fly worked well today in the rain and sleet at alyeska. Has also been a companion in European market shopping, New Mexico and Alaska day hikes, and mucb more.

This bag is lightweight, sturdy and the perfect size. It works great for a climbing day, short hike, and even travel through airports. It looks flashy too. The small pouch on top works great for quick access items and the zippers don't catch. The phone pouch actually did come in handy for a day hike with a full sized iPhone.

I originally got this pack for day hikes, snowboarding, and multi-pitch climbs, but I found myself using this pack for my travels as well b/c it's a great size pack and it'll fit my 13" macbook. The pack looks amazing and is well-constructed. One thing I also love is that it came with a rain cover.

Nice day pack

I like it for day hikes to throw a jacket, water, and some munchies for me and pupper. It might fit a laptop for air travel?. It rides well and is very light without causing a lot of sweat.

Nice little bag for day trip.

Has a few options that make this back great. Small roll out pocket for cell phone, rain cover built in the bottom.

Perfect Travel Companion!

The Lithium 15 backpack contains all of the features and functions of a larger hiking bag, but in a convenient size for day trips or air travel. I recently used this on a multi-leg cross-country trip where I needed a compact bag for airlines and for quick hiking around local trails. The small size was perfect for the plane, while the features such as chest and waist straps, hip belt packets, and integrated rain fly (!!!) came in handy. I'd recommend this to anyone who is looking for a small bag to supplement their normal backpacking and/or travel gear. You won't be disappointed with the build quality or features packed into this 15L gem!
