Naturehike Cooler Family — Long-Lasting Cooling, Effortless Mobility, Versatile Use
From mountain solo treks to coastal road trips, Naturehike delivers a complete outdoor cold-storage solution with three different cooler sizes: 17L, 24L, and 36L. All three models share the same core design language: a  food-grade PP interior  (safe for direct food contact), a  thickened PE exterior  (impact-resistant and scratch-proof),  built-in cup holders  (drinks within easy reach), and a  load-bearing lid  (doubles as outdoor seating).
Key Features:
Capacity & Ice Retention: All three models feature   high-density PU foam insulation   to minimize cold air loss. The 36L model, with its   thickest 28mm insulation walls , takes the crown for the longest runtime in the family — 9 hours more than the 24L, enough to power an entire week off-grid.

Portability: 17L & 24L : Both feature a  carry-style design . The 17L comes with a reinforced handle and handle fixing slot, weighing just  2kg  empty. The 24L weighs  3.4kg  — light enough to carry with one hand, ideal for short-distance transport and getting in and out of the car. 36L : The  only model equipped with a telescoping handle and all-terrain wheels . No need to carry it when fully loaded with 45 cans — just roll it like luggage. Sand, grass, gravel, or mud — the all-terrain wheels handle it all with ease, requiring minimal effort from a single person.
Load-Bearing Lid: All three models feature structurally reinforced lids that double as outdoor seating:
17L: Supports up to 80kg / 176lbs
24L & 36L: Both support up to 100kg / 220lbs .
At camp, just sit right on the cooler — no need to carry extra folding chairs. The larger 36L box offers an even more stable seating platform, making it a true "multi-function table/stool" at the center of your campsite.
Sealing System: 
17L: Features a high-seal lid that closes tightly to prevent melted water from leaking out. 24L & 36L: Upgraded to TPU latches + silicone sealing rings. TPU latches are flexible, temperature-resistant, smooth to open/close, and built to last. The silicone sealing ring fully conforms to the rim, creating a closed-loop seal that keeps water inside even when the cooler is tilted or jostled. All three feature food-grade PP interiors — ice and food can touch the surface safely — and thickened PE exteriors that resist impacts and scratches in any outdoor environment.
Cup Holders & Details: All three models feature built-in cup holder grooves on both sides — coffee mugs, beer cans, or water bottles stay stable and within arm's reach. The TPU latches on the 24L and 36L models are easy to operate even with gloves on. Plus, all three models come in multiple color options to match your personal style.
