RIBCORE™
Press down at the hip and the load travels the length of the pad instead of stopping where it landed. The ribs also hold the reflective film off the fabric you sleep on, so there’s less crinkle every time you turn over.

| Season | R-value | Suggested Using Temp | Extreme Operating Temp |

| Warm Weather | R1–2 | >50°F | >10°C | >36°F | >2°C |
| Three Season | R3–4 | 32–50°F | 0–10°C | 18–36°F | −6 to 2°C |

| Extreme Cold | R8+ | −13 to 3°F | −25 to −16°C | −31°F and below | −35°C |
An ASTM R-value is a lab number. It makes pads comparable to each other. It doesn't predict your night — that depends on your bag, the ground, humidity, and how you sleep.

SHAPED BY A SNOW TROUT
NAMED FOR GENYEN. SHAPED BY A SNOW TROUT
Genyen Peak, 20,354 ft | 6,204 m
Hengduan Mountains
Hengduan Mountains
A storm pinned the team beside a glacial lake below Genyen. They waited it out watching the lake's outflow, where a snow trout held its place in current that would have pushed anything flat downstream. Nothing about that water was level. The fish didn’t need it to be.
GENNYE took its shape from that fish, steady on ground that is never level, and was built warm enough for the nights that stopped the team in the first place.
FAQS
How do I choose between R3.9, R6, and R8.8?
Each tier maps to an ASTM-tested temperature band: R3.9 for above 23°F (-5°C), R6 for 23°F to -4°F (-5°C to -20°C), R8.8 for -8°F (-22°C) and below. If your trips regularly span two bands, size up.
What does HexCore™ do that flat Mylar layers don't?
Flat Mylar layers compress under body weight, collapsing the air gap that provides insulation at the highest-pressure contact points. HexCore™ three-dimensional honeycomb cells hold Mylar in discrete volumes — the cellular structure resists compression independently, maintaining thermal geometry where it matters most: directly under the torso and hips.
What's the difference between the fish-profile and rectangular configurations?
Fish-profile (21.7 in / 55 cm shoulder, 13.8 in / 35 cm foot) is the lighter option and pairs with mummy sleeping bag geometry. Rectangular variants — including a 76.8×51.2 in (195×130 cm) Double — suit users who move during sleep or share the pad. Weight difference is approximately 6–9 oz depending on size.
Is the valve system the same as GENNYE XT?
Yes. All GENNYE PRO configurations use CrozzValve™ — two-stage, mechanically independent inflate and deflate ports — and include the same dual-function pump sack.
What is fish-profile — is it similar to a mummy sleeping bag shape?
Yes. Fish-profile follows the same logic as a mummy bag: full shoulder width where the body is widest, tapering toward the foot where contact surface narrows. GENNYE is 21.7 in (55 cm) at the shoulder and 13.8 in (35 cm) at the foot. The taper removes material that carries no body weight, reducing pack weight without reducing the insulated surface under your body. Users who move frequently during sleep, or who use a rectangular sleeping bag, should consider the GENNYE PRO in rectangular configuration.
