Big Agnes
Big Agnes Torchlight EXP 20
No citable owner-review average published for this one, so no stars.
Two zippered expansion panels run from shoulder to footbox and add five inches of girth on each side — ten inches in total — which makes this the only bag here whose fit you can change after you have bought it. Zip them shut on a cold night and it is a normal mummy; open them on a warm one and it is closer to a semi-rectangular bag. That is a genuinely good answer to the problem that a bag tight enough to be warm is too tight to sleep in. The trade is 40 ounces and a manufacturer-only 20-degree rating with no lab figure behind it.
Label against lab
No ISO or EN rating is published for this one — the 20 °F is Big Agnes’s own figure, with no lab test behind it. Where a maker publishes loft or fill weight instead, those are the numbers worth comparing. What the standards measure
At that temperature the pairing table wants at least an R 4 pad underneath it.

What it does well
- Ten inches of expandable girth across two zippered side panels — the only adjustable-fit bag in this catalogue.
- The PadLok system attaches the bag to a pad so you roll inside it rather than rolling off.
- 650-fill DownTek is PFC-free hydrophobic and RDS-certified.
- 20-denier recycled polyester shell is tougher than the nylon used on most bags at this price.
- Three lengths, and the expansion panels mean each length covers a wider range of builds.
What it costs you
- No ISO or EN figure at all — the 20 is Big Agnes's own number and there is nothing published to check it against.
- 40 ounces in the Regular, heavy for a 20-degree down bag.
- The expansion panels add zips, weight and two more seams that can leak heat.
- Big Agnes publishes neither fill weight nor shoulder girth, so it can't be compared on the physical numbers.
- Opening the panels means heating a much larger volume, so the 20-degree claim only applies zipped shut.

Big Agnes
Big Agnes Lost Ranger 3N1 15
Two bags that nest: an outer 15-degree shell and an inner lighter bag, usable separately for summer, together for winter, or as a single mid-weight bag in between. It is the most flexible sleep system in this catalogue and also the heaviest way to buy that flexibility — 44.5 ounces for the pair. For a family or a couple who camp from June through October and want one purchase to cover it, the argument holds. For a backpacker it does not.
Best for: One purchase covering summer through shoulder season

REI Co-op Magma 15
The Magma is the bag most people who compare specs end up buying, and the numbers explain why: 850-fill down, 23.3 ounces of it, an ISO comfort rating of 21 °F and an ISO lower limit of 9 °F, for $399. That is a genuinely six-degrees-warmer comfort figure than the 15 in the name, which is the opposite direction from almost every other bag in this catalogue — REI named the bag closer to its limit than its comfort and then published both, which is the honest way round.
Best for: Backpackers who want the best published numbers per dollar

NEMO
NEMO Riff 15
The Disco's trimmer, more expensive sibling: the same Spoon silhouette and the same Thermo Gills in a narrower cut with 800-fill down instead of 650. That buys four ounces and half a litre of pack space for $100. Whether that is a good trade depends entirely on how far you are carrying it — for a weekend it is not, for a long trail it very much is.
Best for: Side sleepers going long enough that four ounces matters
