An underquilt is an insulated layer that hangs underneath your hammock to trap warm air and block cold wind. Unlike sleeping pads or blankets inside the hammock, an underquilt stays in place and doesn’t compress, so it retains maximum warmth. It’s the most effective way to stay warm in a hammock, especially during winter camping or chilly spring/fall nights.
Why You Need an Underquilt
🌙 Warm Sleep
Underquilts eliminate cold spots by insulating the entire bottom of your hammock. You’ll sleep warmer and deeper without shivering.
🎒 Lightweight & Packable
Modern underquilts are made with down or synthetic insulation that packs small—ideal for backpacking gear and ultralight setups.
⛺ Easy Setup
Attach to your hammock suspension in minutes. No need to wrestle with a sleeping pad inside the hammock.
🌲 Versatile
Works for all seasons. Pair with a lightweight top quilt for summer, or a heavy winter underquilt for snow camping.
How to Choose the Best Underquilt
When selecting an underquilt, consider these key factors: temperature rating, insulation type (down vs. synthetic), weight, and size. For most three-season camping, a 20°F to 40°F underquilt is a great all-rounder. If you often camp in wet conditions, synthetic insulation performs better when damp. Down offers superior warmth-to-weight and is more compressible—perfect for backpacking gear.
Also check the length: full-length underquilts cover your entire body, while 3/4-length quilts save weight and pair with a foot pad. For winter hammock camping, consider a winter sleeping bag or overquilt combo.

How to Use & Maintain Your Underquilt
Attach your underquilt to the hammock suspension using the included shock cords. Adjust the tension so the quilt sits snugly against the hammock without gaps. Ventilation is key: if you’re too warm, loosen the suspension or slide the quilt to one side. To clean, follow the manufacturer’s instructions—most down quilts can be machine-washed on gentle with special down soap. Always store your underquilt uncompressed in a large sack to maintain loft.
