It is almost identical to the Revelation model, with the key difference being that the Enigma features a closed, non-zippered foot box. This makes it a few grams lighter and more compact. Minimalist ultralight quilt suitable for summer season. ## Materials The Enigma quilt is constructed from **10 denier nylon** (23 g/m²), which is pleasant to the touch and offers an ideal balance between durability, breathability, and low weight. The fabric is treated with a **durable water-repellent (DWR) coating** on the outer side, which protects the down of the sleeping bag from light condensation or a few drops of water. The quilt in size Regular/Regular is filled with **263 grams of duck down with a fill power of 850 cuin** ([US method](/blog/everything-you-need-to-know-about-down)) and its total weight is a beautiful **416 grams**! The quilt size Long / Wide is filled with **300 grams of down** and has a total weight of **470 grams**. The down is ethically sourced and has certification [RDS](https://textileexchange.org/standards/responsible-down/). Enlightened Equipment states a limit temperature for its quilts, which corresponds to standard measurements EN 13537/ISO 23537. The comfort temperature is about 5°C above the limit temperature. [Video](https://youtu.be/8CJO2Kw-MQE) ## Construction EE relies on a unique **U-shaped chamber construction** in its quilts, which combines the best features of traditional horizontal and vertical chambers. Vertical chambers prevent down from shifting to the sides, which most often occurs when sleeping on your side. Horizontal chambers in the foot box maintain maximum loft and keep the down exactly where it's needed. Between the individual chambers, there are **vertical baffles** that significantly reduce heat loss at the junction of two chambers compared to simpler sewn through constructions. To save weight and improve packability, quilts are stripped of all unnecessary features. **On its back side from the waist up, inefficiently used down is removed**, which would be mostly compressed under your body and practically serve no purpose. To keep the opening on your back underneath you at all times, the quilt is attached to the sleeping pad using elastic straps. The quilt remains in a fixed position, and you can turn inside it. The quilt can be used with any type of sleeping pad (inflatable or foam). Additionally, the **quilt does not have a hood**; you can replace it with a hat or a hooded down jacket/sweatshirt. ## Features At the top of the quilt (behind the neck) there are **two pairs of plastic snap fasteners and a drawstring** with a barrel lock to minimize heat loss around the neck. You will receive **one round strap and one flat strap with buckles** for the sleeping pad. The round strap is threaded around the sleeping pad, and the buckles on the strap are connected to the buckles on the quilt, ensuring that the quilt is secured to the sleeping pad and the opening on your back remains underneath you. The flat strap is used to attach to the top buckles of the quilt and to tighten the opening. **Enigma has, unlike a quilt** [**Revelation**](/p/enlightened-equipment-revelation-quilt-20f-6c)**, completely sewn foot box.** This means losing the option of fully opening the quilt and using it as a blanket, but on the other hand, you save a few grams and improve packability a bit. The foot box will also be slightly warmer, making it more suitable for those who always have cold feet.

A **simple travel storage sack** made of waterproof nylon is included with the quilt. In this sack, the quilt has a cylindrical shape with a height of 30 cm and a diameter of 17 cm. However, by using a compression sack, you can reduce the volume of the quilt by an additional 40%.
