Description
What Makes the New OTUL Beta 400 down Underquilt Exceptional?
When sleeping in a hammock, a traditional sleeping bag gets compressed between the body and the hammock fabric, significantly reducing its insulation on the bottom and sides. This can be uncomfortable even during warm summer nights. The OTUL underquilt creates an insulating layer of warm air around the hammock, ensuring a peaceful and comfortable sleep. It replaces the need for a traditional foam pad or self-inflating mat.
The OTUL Beta 400 is the latest model in the OTUL series. It measures 215 × 120 cm, weighs 750 g, and provides comfort in a temperature range of -8 to 8°C. It contains 400 g of down, the ideal amount for hammock sleeping from autumn to spring.
Collaboration Lesovik × Małachowski
Lesovik teamed up with the renowned manufacturer MAŁACHOWSKI, a specialist in down equipment, to create a new line of products designed for hammock and ultralight camping. The result of the collaboration is the OTUL Beta series of underquilts in both summer and winter variants, featuring an original technical solution with innovative β-chamber construction.
What are Β-Chambers?
The unique construction of the OTUL Beta underquilt uses B-shaped chambers. When wrapped around the hammock, the “bellies” of these chambers join together for better insulation. In laboratory tests, this construction outperformed traditional H-chambers with the same amount of down. The central chambers have a larger volume, allowing for better loft where it’s most needed, such as the shoulders, back, and sides.
Comfortable and Secure Attachment
OTUL is compatible with any hammock. Hanging and adjusting takes only 90 seconds, and the insulation can be adjusted directly from the hammock thanks to easily accessible tensioners. There’s no need to get out of the sleeping bag. Thanks to the β-chamber construction, the underquilt can even be hung “inside out” to reduce thermal comfort, which is appreciated on warmer nights above the recommended temperature range.
Tunnels with drawstrings at the top and bottom prevent cold air from entering under the hammock and create space for shoulders and feet, which are prone to heat loss. The multi-chamber design ensures lasting and maximum loft.
What is the UNGAPER System?
UNGAPER is a smart buckle that lifts the underquilt by up to 10 cm, eliminating gaps in the shoulder and foot areas. It minimizes heat loss and increases insulation efficiency.
More than just an Underquilt
Thanks to the quick-release system, the OTUL can be transformed into a down blanket in seconds. It can replace a sleeping bag or serve as a cover during breaks, meals, or rest. Whether you’re waiting for your morning coffee or watching the sunset, you’ll stay comfortably warm.
How to Ensure I Don’t get Cold in a Hammock?
The underquilt should always be used with a sleeping bag or topquilt suitable for the conditions and with appropriate base layers. The underquilt does not replace a sleeping bag or enhance its insulation capabilities. The recommended temperature range is based on testing, tester feedback, and user experience, but individual cold perception may vary depending on condition, wind, or humidity.
Sometimes you may feel cold at 18°C, other times a light sweatshirt is enough at 10°C. Before a night in nature, always:
- eat and drink well
- avoid excessive fatigue
- choose appropriate clothing, stay dry, and protect yourself from the wind
