## Description

If you're looking for something extremely lightweight for the summer months, sleeping in cabins, or a down liner to enhance thermal comfort, the Magic 100 zip down sleeping bag will be a great choice. With the highest quality down with a fill power of 900 cuin and the ultralight Toray® Airtastic fabric at 19 g/m², the sleeping bag weighs only 240 grams and is one of the lightest sleeping bags in the world!

## Why is the product exceptional?

Ultralight down sleeping bag without a hood, weighing just 240 grams, ideal for warmer months.

## Materials

The construction of the sleeping bag uses **Toray® Airtastic 19 g/m fabric**, which perfectly combines low weight, breathability, and excellent packability. The outer side of the fabric is treated with a **permanent water-repellent (DWR) coating**, which retains light condensation or a few drops of water.

The great performance is provided by **105 grams of goose down with a fill power of 900 cuin**. The down to small feathers ratio is 95/5.

## Construction

The sleeping bag has a **simple sewn through chamber construction**, which is standard for summer sleeping bags with a small amount of down. **The width of the sleeping bag at the shoulders is 75 cm and 47 cm at the hips.** Size M is suitable for people up to 178 cm tall.

The sleeping bag has a long **3 mm YKK zipper**. At the feet, you will find a second slider, which is ideal for ventilation.

At the neck, you will find a **drawstring** to minimize body heat loss.

## 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 1,6 liters and dimensions of 18/11 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 eVac Compression Dry Bag UL](/p/sea-to-summit-evac-compression-dry-bag-ul) of a size of 3 l or a classic waterproof bag [STS Ultra-Sil Dry Bag](/p/sea-to-summit-ultra-sil-dry-bag) of size 3 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.
