From Peli: 

The Peli 1600 Case is a watertight, dustproof, chemical resistant, corrosion-proof and virtually indestructible case from Peli Cases UK, offering total protection for your equipment in whatever situation it is faced with. Constructed of ultra-high impact structural copolymer, the Peli 1600 is extremely strong yet lightweight.

Its neoprene O-ring seal that works in sync with ultra-reliable double-throw latches creates a secure, watertight seal, whilst the latches are also easy to open but only when required. An automatic purge valve ensures quick equalisation after changes in atmospheric pressure whilst keeping water out, this pressure equalisation system also ensures that the contents is not abruptly ejected from the case when opening at various altitudes for example.

Peli UK have also kept the comfort of the user in mind, with an ergonomically designed, rubber over-moulded handle for easy, pain-free transportation. Each of the padlock fastening points have been secured with stainless-steel protectors to prevent any unwanted intruders from tampering with padlocks and gaining access to your valuable equipment.

The Peli 1600 case is NATO codified and tested to MIL C-4150J (Military Standard), IP67 (Ingress Protection) and ATA (Air Transportation Association).
