Figure out which replacement stuff sack fits your Rumpl blanket, how to pack it without overstuffing, and when a missing sack is worth replacing.
Quick answer
Match the sack to your blanket's packed size, not its flat dimensions: the Rumpl Replacement Stuff Sack is made to fit most Rumpl blankets, so start there and size up if your blanket is a larger two-person model or you want easier packing.
Why the blanket's packed size matters more than its spread size
A puffy blanket compresses differently depending on its fill and shell, so the number printed on the blanket label rarely tells you the sack size. What matters is how small the blanket rolls or stuffs in practice. If you can compress it into a rough cylinder, measure that cylinder's length and circumference, then compare it with the sack's stated capacity.
A sack that is too small forces you to wrestle the blanket in and strains the seams; one that is far too large leaves dead space and lets the blanket shift around in your pack. Aim for a sack that holds the blanket snugly without requiring you to kneel on it.
When a larger blanket changes the answer
Two-person and extra-large puffy blankets usually need more volume than a one-person throw, even when both use similar materials. If your blanket is on the larger end, test the fit at home before committing: stuff it loosely, check whether the drawcord closes without a struggle, and only then tighten it down.
If the blanket barely fits, don't force it. A slightly bigger sack protects the loft and makes daily packing faster, which matters more than shaving a few grams.
Stuff sack questions, answered
- How do I measure my blanket for a stuff sack?
- Roll or stuff the blanket as you normally would, then measure the length and the distance around the resulting bundle. Compare those numbers with the sack's dimensions; if you are between sizes, choose the larger one. Measure the packed bundle, not the blanket laid flat.
- Can I use any stuff sack, or does it need to be a Rumpl one?
- Any sack with the right dimensions can work, but a purpose-made replacement removes the guesswork. The Rumpl Replacement Stuff Sack is built for most Rumpl blankets, so it is the simplest starting point if you want a like-for-like replacement.
- How do I pack a blanket into a stuff sack without overstuffing it?
- Stuff the blanket in loosely, starting with one end, and push it down gradually rather than forcing the whole blanket in at once. Close the drawcord only when the fabric gives easily; if you have to fight it, the sack is too small. If the drawcord needs two hands and a knee, size up.
- Does a tight stuff sack damage the blanket?
- Compression is normal for travel, but leaving a synthetic or down blanket crammed at maximum compression for months can reduce loft over time. Store the blanket loosely when you are home, and use the stuff sack for transport. Compress for the trip, not for the shelf.
