Cumulus Lite Line 300 - Large - is new improved version of classic and the most popular of Cumulus spring and summer models.

It is characterized by a very low weight of 600g using an advanced cell trapezoid design which gives it a great advantage over the competition. Efficient trapezoid construction combined with fantastic quality Polish goose down make it possible to sleep in comfort at even 4°C.
Made of the tried and tested Pertex Quantum fabric, it weighs 29 g/m². It is a model that more ardent proponents of "Fast and Light" and with the use of extra insulating layers you can even use it in warm winter weather.

The new latest version has a shark-fin foot box construction, this shape is more comfortable and prevents the fabric from creating a tension over your toes, thanks to that down is not commpressed and keep your feet warmer.

New ergonomic design of the hood provide unique comfort. Additionally, Cumulus has added draw cords and tapes to the hood making it more adjustable.

New design of the inner pocket, is bigger now, so you can easily fit a bigger smartphone in it and even a powerbank. It is a mesh pocket so you can see what is inside the pocket without opening it and you can also use your phone while is inside. Pocket zip is ended with florescent cord so you can easily find the pocket in the dark without using a headlamp.

Cumulus has changed their zipper on all Lite Line series. At the top of the zip is now a small flap preventing cold zipper from touching your face and at the bottom you can find a second zipper which helps you to ventilate the feet area in higher temperature. Finally Cumulus solve problem with stucking Pertex fabric in the zipper by using a small plastic zipper guard.
