When it comes to optimizing sleeping bag design, Rab is often considered the master in the industry. With 30 years experience making down sleeping bags, Rab knows a thing or two about designing one. The research they’ve done at Leeds University has helped them uncover the secrets behind the optimum of down to use in any given part of the sleeping bag to get the correct balance between warmth and weight for different conditions.
Not only does Rab know exactly how much down to fill in each compartment for optimal results, these people also know about the crucial factors that make a great sleeping bag. Their sleeping bags are made of lightweight outer layer shell so that the down can achieve maximum loft for better insulation.
The construction of Rab bags are also play an important role in designing the ultimate sleeping bag taking into account the differential cut, chamber shapes and even the direction of the baffles. Mesh side walls are used inside the chambers to save weight and to prevent the down from slipping around inside the sleeping bag.
Rab sleeping bags are color-coded – red being the warmest, orange next step down and yellow less warm. The sleeping bags are also categorized into “Expedition”, “Andes”, “Alpine” and “Neutrino”. “Expedition” and “Andes” are the warmest while weight becomes a priority in the “Alpine” and “Neutrino” range.
