Designed around the way you actually sleep in a hammock.

The Asym Underquilt takes the natural diagonal lay of a hammock and uses it to your advantage.
By shaping the quilt to match how you actually sleep, unnecessary fabric and insulation are removed, cutting both bulk and weight without losing warmth where it matters most.

For comparison:
Regular 167 gsm underquilt — 750 g / 6.7 L
Asym underquilt — 520 g / 4.2 L

That’s less to carry, less to pack, and just as cozy through the night.

Features

• Climashield® APEX insulation — continuous filament synthetic fill that stays warm even when damp.

• 20D Nylon fabric — DWR-coated and PFAS-free, lightweight, soft, and weather-resistant.

• Clew suspension system — a rare and innovative attachment method that makes setup faster, simpler, and fully adjustable. Fits virtually any gathered-end hammock, and lets you fine-tune the quilt position up to ~50 cm. No extra straps or complicated rigging required.

• Reversible design — works for both left or right diagonal lay; just flip the quilt.

• Optimized asymmetrical cut — warmth where you need it, nothing extra where you don’t.

• Handmade in Lithuania, field-tested in real hammock conditions.

Optional: Cold Spot Boost 

Cold air tends to find your backside first — so there’s now an option to fight back.
The Cold Spot Boost variant adds a localized layer of extra insulation in the hip/seat area, giving you more warmth where it’s most needed without adding much bulk.

Perfect for cold sleepers or deep autumn nights.
Add only ~20–30 g of weight — feel the difference all night long.

In short

Less bulk. Less weight.
Same warmth — exactly where you need it.
Clew suspension makes setup effortless.
Made by hand, built for hammock sleepers who know their lay.
