- Weak point
- Draughts at the edges
Why the back of a sleeping bag is wasted
Lie in a sleeping bag and roughly a third of its down is underneath you, squashed to nothing between your body and the pad. Compressed insulation doesn't insulate, so that down is carrying weight and doing no work. A quilt deletes it, along with the hood and usually the full-length zip.
What you actually save
What you save is real: commonly several ounces against an equivalent bag, plus noticeably less packed volume. What you take on is draught management. A quilt is held to the pad by straps and it seals against your body rather than around it, so a restless sleeper can let cold air in at the edges. Most people adapt within a few nights, and some never get on with it.
What a quilt demands of your pad
It works best with a warm pad, because the quilt is trusting the pad completely for everything underneath you. It also pairs naturally with sleeping in a warm hat, since there's no hood. If you already own a good pad and you're chasing weight, it's one of the larger single savings available in a sleep system.
What this means when you're choosing
- A pad with enough R-value, since the quilt trusts it completely
- A pad attachment system that suits how much you move at night
- A closed footbox unless you specifically want the summer versatility
Backpacking quilt vs Sleeping bag
| Backpacking quilt | Sleeping bag | |
|---|---|---|
| Insulation underneath | None. The pad does that job | Present, and crushed flat by your weight |
| Weight and bulk | Several ounces lighter, packs noticeably smaller | Heavier for the same warmth on top |
| Drafts | Possible if the straps or pad are wrong | Sealed, especially with a draft collar |
| Pad demands | High. The pad carries everything below you | Lower, though a cold pad still ruins the night |
Which to pick: A quilt if you have a warm pad and do not thrash in your sleep. A bag if you move a lot, sleep cold, or want one fewer variable at 2am.
The common mistake
Pairing a quilt with a thin pad
A quilt deletes the insulation under you on the grounds that it was crushed and useless. That is only true if the pad is doing that job. Put a quilt on an R 2 pad in October and the cold you feel is the ground, not the quilt.
Common questions
Are quilts warm enough for cold weather?
Yes, with the right rating and a good seal to the pad, and plenty of people use them below freezing. They're less forgiving of a bad setup than a mummy bag, so cold nights punish sloppy strapping.
Do I need a special pad for a quilt?
Not special, but it needs enough R-value, because the quilt has nothing underneath you. Pad straps are what hold the quilt in place, and most quilts ship with them.
