Source: rei.com (verified 2026-07-11) · corroborated by bettertrail.com. Both fetched dated reviews explicitly identify this as the "REI Co-op Helix Insulated Air Sleeping Pad" and agree on its defining specs — 4.9 R-value, two-layer internal reflective insulation, 3 in loft, 30D face fabric, mummy shape, and included pump-sack inflation — confirming this is the exact model (not the non-insulated variant). Better Trail (Updated Jan 20, 2025) provides a spec table (Type: Air, R-value 4.9, Weight 1 lb 5 oz, Packed Size 10 x 5 in, Thickness 3 in, Fabric 30D polyester, regular size 72 x 20 in, "only available in mummy shapes") and lists the price as $169; CleverHiker (Nov 20, 2024) corroborates R-value 4.9, 21 oz weight, 3 in thickness, 30D fabric, pump-sack inflation, and $169. REI's own manufacturer product page (source.url, product ID 202288) returned HTTP 403 to automated fetching, so every published value and the price were verified verbatim against these two independent dated reviews; metric spec values are exact conversions of the imperial figures those pages state.
