{"product_id":"pelican-1556-air-long-deep-hard-case","title":"Pelican 1556 Air Long\/Deep Hard Case","description":"\u003cp class=\"product-lead\"\u003eThe Pelican 1556 Air is a long\/deep-format hard case built from Pelican's proprietary HPX² polymer (a polypropylene blend engineered to be up to 40% lighter than standard case materials) while meeting IP67 and MIL-SPEC certification for waterproof, crushproof, and dustproof protection. The interior measures 21.63 x 10.76 x 8.97 inches (1.21 ft³), making it sized for gear that is both long and deep. It is available in two configurations: With Foam (Pick N Pluck) or No Foam.\u003c\/p\u003e\n\n\u003ch2\u003eSerious Protection Without the Weight Penalty\u003c\/h2\u003e\n\u003cp\u003eThe 1556 Air's HPX² polymer body delivers up to 40% weight savings over conventional hard-case materials without sacrificing the structural rigidity that IP67 and MIL-SPEC certification demands. For a traveler or overlander hauling sensitive electronics, optics, or precision instruments, that weight reduction translates directly into more usable payload: more headroom within airline carry-on limits and better load distribution in a truck bed or cargo area.\u003c\/p\u003e\n\n\u003ch2\u003eA Seal System Built to Stay Sealed\u003c\/h2\u003e\n\u003cp\u003eThe EPDM O-ring gasket runs the full perimeter of the lid, creating the watertight barrier behind the IP67 rating. The automatic pressure equalization valve, fitted with a Hi-Flow Gore-Tex 3-micron hydrophobic membrane, balances interior pressure as altitude or temperature changes without letting water in. That combination means the case can be taken from a cold vehicle into a warm cabin, loaded onto a plane, or left in the sun without the seal fighting pressure differentials that could compromise it over time.\u003c\/p\u003e\n\n\u003ch2\u003eCarry-On Sized, Trolley Equipped\u003c\/h2\u003e\n\u003cp\u003eThe 1556 Air's exterior dimensions (23.43 x 13.52 x 10.57 inches) are sized to meet maximum airline carry-on requirements, and the retractable extension trolley handle and fold-down over-molded carry handle make airport and trailhead transitions practical without a separate cart or second set of hands. Stainless steel padlock protectors at the two latch points accept standard padlocks (0.31-inch hole diameter) for checked-bag or storage security.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIP67 and MIL-SPEC Certified:\u003c\/strong\u003e waterproof, crushproof, and dustproof to certified standards\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHPX² Polymer Body:\u003c\/strong\u003e proprietary polypropylene blend, up to 40% lighter than conventional case materials\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAutomatic Pressure Equalization Valve:\u003c\/strong\u003e Hi-Flow Gore-Tex 3-micron hydrophobic membrane balances pressure and keeps water out\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePress and Pull Latches:\u003c\/strong\u003e ABS double-throw latches with stainless steel padlock protectors (0.31-inch hole diameter)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRetractable Trolley Handle:\u003c\/strong\u003e extension handle plus fold-down over-molded carry handle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePick N Pluck Foam:\u003c\/strong\u003e user-customizable pre-scored foam interior (With Foam configuration only)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLimited Lifetime Warranty:\u003c\/strong\u003e covered against defects in materials and workmanship; made in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eValue\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eExterior Dimensions\u003c\/td\u003e\n      \u003ctd\u003e23.43 x 13.52 x 10.57 in (59.51 x 34.34 x 26.85 cm)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInterior Dimensions\u003c\/td\u003e\n      \u003ctd\u003e21.63 x 10.76 x 8.97 in (54.94 x 27.33 x 22.78 cm)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eInterior Volume\u003c\/td\u003e\n      \u003ctd\u003e1.21 ft³ (0.03 m³)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLid Depth\u003c\/td\u003e\n      \u003ctd\u003e2.00 in (5.08 cm)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBottom Depth\u003c\/td\u003e\n      \u003ctd\u003e6.97 in (17.7 cm)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePadlock Hole Diameter\u003c\/td\u003e\n      \u003ctd\u003e0.31 in (0.79 cm)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBuoyancy\u003c\/td\u003e\n      \u003ctd\u003e84.95 lbs (38.53 kg)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight (With Foam)\u003c\/td\u003e\n      \u003ctd\u003e11.20 lbs (5.08 kg)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWeight (No Foam)\u003c\/td\u003e\n      \u003ctd\u003e9.75 lbs (4.42 kg)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBody Material\u003c\/td\u003e\n      \u003ctd\u003eProprietary HPX² Polypropylene Blend\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLatch Material\u003c\/td\u003e\n      \u003ctd\u003eABS\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eO-Ring Material\u003c\/td\u003e\n      \u003ctd\u003eEPDM\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePurge Vent Material\u003c\/td\u003e\n      \u003ctd\u003eHi-Flow Gore-Tex 3 Micron Hydrophobic Non-Woven\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePurge O-Ring Material\u003c\/td\u003e\n      \u003ctd\u003e70 Shore Nitrile\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOperating Temperature Range\u003c\/td\u003e\n      \u003ctd\u003e0°F to 140°F (-18°C to 60°C)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCertifications\u003c\/td\u003e\n      \u003ctd\u003eIP67, MIL-SPEC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eWarranty\u003c\/td\u003e\n      \u003ctd\u003eLimited Lifetime\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCountry of Origin\u003c\/td\u003e\n      \u003ctd\u003eUSA\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThe 1556 Air suits travelers, overlanders, and field professionals who need to protect long and deep gear (camera bodies with lenses attached, medical or lab instruments, firearms, or precision electronics) in a case that qualifies as airline carry-on and can withstand outdoor temperature extremes from 0°F to 140°F.
