Klymit Insulated Hammock Sleeping Pad

Quick verdict: The Klymit Insulated Hammock V is a hammock-shaped inflatable pad with side wings, non-slip zones, and synthetic insulation. It offers a pad-based alternative to an underquilt, but the current manufacturer technical table lists 36 oz—not the “under 1.5 lb” figure previously shown here.

Who is this for?

Best fit: hammock campers who prefer an inflatable pad, want one insulation component that sits inside the hammock, or need compatibility with common single- and double-wide hammocks.

What you get

Klymit lists the Insulated Hammock V pad and an emergency repair patch. A hammock is not included.

Verified technical data

Dimensions: 78 × 47 × 2.5 in.

Packed dimensions: 8 × 5.5 in.

Material: 20D polyester.

Weight: the current Klymit EU technical table lists 36 oz / 1,021 g. Another bullet on the same page says 35 oz, so confirm the selected model and packaging when exact pack weight matters.

R-value guidance

Klymit currently lists an R-value of 1.9 under ASTM F3340-18 for the EU model and warns that R-values printed on older packing bags no longer correspond to current test standards.

Do not compare a legacy package number directly with a current ASTM value. Confirm the exact model, SKU, and current standardized rating before using the pad in a temperature-critical sleep system.

Warmth and season limits

• An R-value describes resistance to heat flow; it is not a guaranteed comfort temperature or proof of “true four-season” performance. Clothing, sleeping bag or top quilt, wind, humidity, metabolism, inflation, and hammock fit all affect warmth.
• Compatibility
• Klymit describes the current pad as fitting standard single and double-wide hammocks. Verify the 78 × 47 in shape against unusual bridge, spreader-bar, or narrow hammock designs before purchase.
• Design
• Klymalite synthetic insulation is placed within the air chambers to reduce heat transfer between the upper and lower portions of the pad.
• The V-chamber pattern is designed to limit air movement, while the side wings wrap upward to reduce exposed areas along the hammock’s sides.
• Coated non-slip zones on the top and bottom are intended to reduce movement between the hammock, pad, and sleeping bag.
• Setup

Inflate the pad inside or beside the hammock, position the wings evenly, and test the diagonal lay. If the pad feels too rigid, reduce inflation gradually while keeping enough air to prevent bottoming out.

• Practice before an overnight trip and carry the supplied patch. Check for leaks, valve damage, abrasion, and shifting before relying on the pad in cold conditions. Evidence & source note: Specifications, compatibility, construction details, and the R-value warning on this page are based on Klymit’s current Insulated Hammock V manufacturer documentation. Conflicting legacy R-values, sub-1.5 lb weight claims, guaranteed warmth, universal ground-use, and “all outdoor conditions” durability claims from the prior copy were removed.

• Tradeoffs
• At roughly 36 oz, this is not an ultralight insulation choice. An internal pad can also change the hammock’s feel and may require repositioning, while any inflatable pad introduces puncture and leak risk.
• Compared with an underquilt, the pad sits inside the hammock and can be easier to feel or shift beneath you. An underquilt preserves the hammock interior but requires external suspension adjustment.
• Skip it if
• Choose another system if minimum pack weight is the priority, if you dislike sleeping directly on an inflatable pad, or if your expected conditions require more insulation than a currently listed R-value of 1.9 provides.
