Sizing Guide: Sleeping Bags


Getting a good night's sleep when it's cold out there is super important. Luckily, we're masters of insulation. By choosing a Rab® sleeping bag, you know you're going to have some sweet dreams, no matter if you're on an alpine bivi, or in the back of your camper. However, picking the right size is key.

In this guide, we look at the different fits and sizes of our bags. Outlining their benefits and ideal uses.

FIT

You don't want your bag too big, or too small. Either way, you'll lose heat. You also want to be comfortable.

Our bags come in three shapes:

  • Mummy shaped - your comfy option. These are broader at the shoulders and get slightly narrower towards the foot box. Great for side sleepers or those who like to have a little wiggle-room. Used in: Ascent, Solar, Expedition, Andes
  • Tapered Mummy shaped - the performance option. Tapered mummy bags are the 'slim fit' of sleeping bags. These are close at the shoulders and tighter at the feet to reduce any excess air. They are the most thermally efficient option, pack the smallest and weight the least. Used in: Neutrino, Neutrino Pro, Mythic, Mythic Ultra, Alpine Pro
  • Extra Wide Mummy shape - spacious option. You guessed it. These are extra wide and have lots of room inside. Ideal for car camping or casual users. Used in: Morpheus

SIZE

Alongside the fit, comes the actual size of the bag. You want to choose a sleeping bag that's closest to your own measurements.

Each model has its own fit. And, the internal measurements of all the fill variations for that model are the same. For example, getting in an Ascent 900 feels the same as getting in an Ascent 300. The internal dimensions stay the same. We change the outer dimensions of the bag to accommodate for the extra down filling.

We have three basic sizes, Women's, Regular, and XL. Broadly speaking these are based on height, though the widths are also different.
