Hotcore Hypnos 4 Unisex Sleeping Pad 4.5 R-Value

Hotcore | Hypnos 4

If the Hypnos 3 is your reliable summer road-trip companion, the Hotcore Hypnos 4 is your cold-weather insurance policy. You don't need to be summiting a glacier to appreciate a true 4-season pad; sometimes a late-fall camping trip or a particularly frosty Canadian spring night is enough to drain your body heat and ruin your sleep. Boasting an impressive 4.5 R-Value and 2.75 inches of loft, this pad puts a serious, reliable barrier between you and the freezing ground. It retains the exact same comfortable, cold-spot-eliminating baffle wall construction and effortless roll-top pump sack as its lighter sibling, but beefs up the Thermolite® EcoMade insulation so you can sleep soundly when the temperatures plummet.

• 4.5 R-Value Insulation: Upgraded with a dense layer of eco-conscious Thermolite® EcoMade synthetic fill to actively reflect and trap body heat when resting on frozen ground or snow.
• 2.75" Baffle Wall Construction: Creates a stable, 2.75-inch thick flat sleeping surface that prevents cold spots and supports side, back, and stomach sleepers equally.
• Pump Sack Inflation: Includes a roll-top stuff sack that doubles as an inflation bag, saving your breath and keeping freezing moisture from your lungs out of the pad's interior.
• Large Tapered Shape: Generously sized at 6'4" to comfortably accommodate taller campers, while the tapered design easily slots into your tent alongside bulky winter gear.
• Field-Ready Reliability: Comes with an included repair kit so you are never left sleeping directly on the cold earth if a mishap occurs.
