Cumulus Lite Line 400 - is the new improved version of the warmest bag of the family of Lite Line sleeping bags.

The advanced, trapezoidal design gives it a great advantage over the competition, which generally uses simple H-chamber structure with this mass of down. However, Lite Line 400 weighs less, because it is only 705 g, also thanks to excellent Pertex Quantum fabric, weighing 29 g/m², which is ultralight but downproof and nicely soft in touch. This sleeping bag is also suitable for use in light weather conditions and will keep you warm even in close-to-winter conditions weighing much less than 1 kilo.
The sleeping bag is an excellent product for camping from early spring to late autumn.

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. Lite Line 400 is simply best-seller.

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.

Lite Line 400 filled with Polish goose down of absolute top quality is hard to beat in weight to insulation comparision with the others. Durable and ultra light, good choice for demanding whole year round use and for those who feel cold even in the middle of the summer.

Review from

“I was a bit concerned about the fabric at first. Pertex Quantum, when you see it in the flesh, does not convey a reassuring feeling of strength. It is crazy light per square meters thought (35 g / m²) and very soft. Just what you want to make an ultra light sleeping bag. I always take great care when handling my gear and, after 3 years of decent use, the fabric of the bag is not showing any signs of weakness. There is the odd feather coming out now and then, which is pretty normal for a down bag and a few loose threads only. You’ll have to be very careful of course because any sharp object like crampons, pointy rocks and bushes would open up the Pertex fabric in no time. I am not holding it against the Cumulus Lite Line 400, when you want low weight, resistance is the first compromise you’ll have to make.”  Read more...
