Rab Lab Sleeping Bag Weight and Packability Explained

Warmth is the primary concern when buying a sleeping bag but it is also important to consider both the weight and pack size. It is possible for two sleeping bags to have a similar temperature rating but very different weights and packed sizes. For some people, warmth is the only concern. If you’re arriving at your camping location by car or setting up a basecamp then a bulky, heavier bag might be fine, but if you’re carrying your gear in the mountains, then every gram is important. For example, if you compare two of our bags, the Neutrino Endurance 400 and the Summit 600 they both have a similar temperature rating, (-6°C and -6.5°C respectively), but the Neutrino Endurance is 285g lighter and packs down to 18 x 27cm rather than the 22 x 39cm of the Summit. Both bags will keep you warm, but if you’re travelling light or have limited space in your pack, then the Neutrino Endurance is clearly the better choice. The trade off is that the 800 fill power down used in the construction of the Neutrino Endurance 400 makes it considerably more expensive. All of our sleeping bags come with a stuff sack, some of which are waterproof. If you are storing your down sleeping bag for an extended period, we do not recommend using a stuff sack as this can impair the down’s natural loft. To avoid this, we also provide you with a much larger, cotton storage bag for when your bag is not in use.
