In its price range, it's hard to find a sleeping bag that can compete with it in terms of weight, performance, and packability. It’s the perfect choice for all kinds of trips from spring to autumn. Those who are more cold-resilient, adding an extra layer, can even handle temperatures slightly below freezing. Cumulus Lite Line 400 is a lightweight, packable, and reliable sleeping bag for all kinds of adventures. ## Materials The construction of the sleeping bag uses **Pertex Quantum fabric 29 g/m²**, which perfectly combines low weight, durability, breathability, and packability. The outer fabric is treated with a **durable water-repellant (DWR) coating** that retains light condensation or a few drops of water. The excellent performance is provided by **400 grams of goose down with a fill power of 850 cuin**. The down to small feathers ratio is 95/5. The upper chambers are separated from the lower ones and are filled with a slightly larger amount of down. The down is distributed here in a ratio of 55/45. ## Construction The sleeping bag uses **trapezoidal chambers** that prevent the formation of "cold spots" at the seam of two chambers. The width of the sleeping bag at the shoulders is 76 cm and 66 cm at the hips. Based on our experience, the basic size M is suitable for individuals with a maximum height of 183 cm. The foot box construction named **Shark-fin** prevents down compression, is comfortable, and provides better thermal performance than standard constructions. ## Features For easy orientation, the tightening of the hood and collar is differentiated; the hood is tightened with a flat strap and the collar with an elastic band. The last chamber at the neck is filled with a larger amount of down, creating a **comfortable collar that prevents heat loss**. Inside the sleeping bag, there is a **mesh pocket** for a mobile phone, earplugs, or other small items. The sleeping bag features a 175 cm long YKK zipper with an extended slider to prevent it from snagging on the fabric during zipping. At the foot area, you'll find a second slider, which is ideal for ventilation. Behind the zipper on the inner side, there is a **down-filled insulating tube** that minimizes heat loss through the zipper itself. Two Cumulus sleeping bags with **opposite zippers (left + right) can be connected together**. ## Sleeping bag accessories **A simple travel storage sack is included with the sleeping bag.** The sleeping bag has a cylindrical shape with a volume of 5,7 liters and dimensions of 25/17 cm (height/diameter). The original sack cannot be further compressed and is not waterproof, so we recommend getting a sack that that solves both problems. The ideal choice is [STS compression sack eVENT Ultra-Sil](/p/sea-to-summit-evac-compression-dry-bag-ul) of size S/M or a classic waterproof bag [Sea To Summit Ultra-Sil Dry Sack](/p/sea-to-summit-ultra-sil-dry-bag) about size 8-10 l. **You also get a large storage bag for home use** with the sleeping bag, so the sleeping bag isn't unnecessarily compressed for a long time.
