Quick verdict: Use a suitable pad you already own to try hammock sleeping without buying a whole new insulation system. Consider an underquilt when regular hammock use justifies a dedicated fit and you want insulation suspended outside the hammock.

The insulation below you needs its own plan
A sleeping bag’s insulation is compressed underneath your body. REI explains why that matters in a hammock and describes two approaches: a pad inside or an underquilt suspended outside. An underquilt is not a top quilt, and it does not remove the need to plan the rest of your sleep system.
Start by deciding whether hammock overnighting will be occasional or regular. The most economical trial may use a suitable pad you already own. That gives you a chance to assess the sleeping position before purchasing equipment dedicated to a style of camping you may not enjoy.
Where an underquilt earns its premium
A dedicated quilt can make sense if a pad repeatedly shifts or interferes with the sleeping position you prefer. Check its length, the coverage around your shoulders and feet, and how it attaches to the specific hammock. Universal compatibility claims still deserve a look at the actual suspension.
Do not select by a temperature number alone. Ratings and comfort depend on the product, fit and overall setup. A gap that allows airflow can undermine an otherwise expensive quilt. Read the manufacturer’s fitting instructions rather than expecting the premium material to compensate for an unsuitable attachment arrangement.
Why keeping a pad can be good value
A sleeping pad is versatile when trips alternate between a tent and hammock. That may outweigh the convenience of a dedicated underquilt for someone who only hangs occasionally. Check whether the pad fits the hammock comfortably and whether any compatible retention sleeve or accessory is needed.
The comparison is not simply cheap foam versus expensive down. Pads and quilts come in several constructions and prices. Compare the complete setup you would actually pack, including suspension, storage and any accessory required to keep the pad in position.
Buy for repeated use, not a theoretical ideal
For a first experiment, avoid replacing a good ground-sleeping kit before you know that hammock sleeping suits you. Upgrade when you can identify the problem the underquilt will solve: shifting, coverage or comfort in an otherwise suitable system. Keep the pad when its flexibility remains more useful.
Canadian buyers should compare complete CAD prices and check replacement suspension availability and the return process. Match the insulation to the expected conditions using the makers’ guidance, and practise the complete setup before a trip. A cheaper supported arrangement that fits properly is better value than a premium quilt bought solely for an impressive specification.
