Hypersphere Ultra 7.5 Marmalade

The Hypersphere Ultra 7.5 Marmalade from the brand Rab is an inflatable bivouac mattress, ideal for 4-season use thanks to its exceptional R-Value of 7.3.

Designed to offer optimal comfort and warmth, this mattress features a thickness of 8 cm ensuring excellent thermal insulation from the cold ground. Its rectangular shape with oversized edges prevents sliding, guaranteeing perfect support throughout the night. The exterior is made of 20D recycled polyester with a PU coating, providing both durability and moisture resistance, while its insulation in Nikwax™ 800 CUIN hydrophobic goose down delivers lightweight and compressible warmth, essential for extreme conditions.

The Hypersphere Ultra 7.5 Marmalade comes with a discreet bi-directional valve that facilitates inflation and deflation, as well as a pump sack, a compact storage bag, and a repair kit for enhanced durability. Its contained weight and ultra-compact folded dimensions (under 35 cm in length) make it an ideal companion for demanding adventurers seeking a high-performance, lightweight, and easy-to-carry mattress.
