MTM Survivor Dry Box Large 10x7x5 Forest Green — Waterproof, Triple-Latch Sealed Gear Case

MTM Survivor Dry Box Large (S1074-11) is a compact, water-resistant storage case with a built-in compass and signaling mirror for protecting essentials in harsh outdoor settings.

This heavy-duty dry box is engineered for people who need reliable, sealed storage on expeditions, water excursions, ATV rides, or when transporting ammunition. Constructed in the USA, the Survivor Dry Box uses tongue-and-groove closure and an O-ring seal held by a triple-latch system to keep moisture and dust out. Thoughtful extras — a compass embedded in the lid, an approved-sized signaling mirror, padlock tabs, and lanyard points — add practical utility for fieldwork and emergency preparedness.

How does the MTM Survivor Dry Box protect gear in wet or dusty conditions?

The case combines mechanical sealing and secure fasteners to block water and particles. An O-ring compresses in the tongue-and-groove track while three separate latches maintain constant pressure across the lid for an even seal.

• Triple-latch system for consistent compression
• O-ring with tongue-and-groove design for water resistance
• Durable polymer shell resists impact and abrasion
• Padlock tabs let you lock contents during travel

What practical tools are built into this dry box for outdoor navigation and signaling?

The Survivor Dry Box integrates basic survival aids so you don’t have to pack extra small items. A compass in the lid helps with rough orientation and the bottom houses a signaling mirror sized to military standards for increased visibility.

• Recessed compass in the lid for hands-free heading checks
• Signaling mirror on the underside for long-distance flashes
• Lanyard attachment points to keep the box secured to gear or a person

Will this case fit ammunition or other travel items, and is it airline-compliant?
