Answers to common questions about using a hammock underquilt for warmth, including setup tips, temperature ratings, and care advice.
Quick Answer
Use a hammock underquilt to add insulation beneath you and stay warm hammock camping. Attach it snugly to the outside of your hammock to eliminate cold spots.
Why an Underquilt Beats a Sleeping Pad
A sleeping pad can slip and create gaps, letting cold air reach your back. An underquilt hangs below the hammock, conforming to your body and providing consistent insulation without the hassle of repositioning.
Underquilts also compress less than pads, so you get more warmth for the weight and pack size—a key advantage for hammock camping.
Trade-Offs to Consider
Underquilts add cost and setup time compared to a simple pad. They also require careful adjustment to avoid gaps at the head and foot ends.
If you camp in very wet conditions, an underquilt can absorb moisture from below, so pair it with a weather shield or choose a synthetic insulation like Primaloft® that retains warmth when damp.
Underquilt FAQ
- How do I attach an underquilt to my hammock?
- Clip the underquilt to the hammock's suspension or integrated loops, then adjust the tension so it sits snugly against the bottom of the hammock. Tighten the ends to seal gaps and loosen slightly if you feel pressure. Check the fit after you lie down; adjust for a snug but not tight fit.
- What temperature rating do I need?
- Choose an underquilt rated for the coldest temperature you expect, plus a margin of 10-15°F. For most three-season camping, a 20°F-rated quilt offers versatility. Consider layering with a top quilt or pad for extreme cold.
- How do I care for my underquilt?
- Follow the manufacturer's instructions—typically machine wash on gentle with mild detergent and tumble dry low. Avoid fabric softeners, which can reduce insulation performance. Store the underquilt loosely in a large sack to maintain loft.
