Be ready for every adventure with the Motion Ellipse 25L Backpack from Heimplanet. This unique bag instantly stands out from the traditional all-black, all-terrain backpacks. Instead, coming in a grey and purple design, the Ellipse is adaptable to your needs. With a nylon spandex layer on the front, the Ellipse actually stretches and conforms to what’s inside. In addition to moving with you, the Ellipse also allows you to increase your capacity instantly. There’s no need for attachments or installing modular pieces. It has the space you need when you need it and stays sleek and slim when you don’t. The 25-liter capacity includes space for up to a 15-inch laptop. Or, for the adventurous, you can add in a 3-liter hydration pack.
