5.11 Tactical - V.XI Poseidon Jacket

The 5.11 Tactical V.XI Poseidon Jacket has a lightweight, packable waterproof shell which is built for professionals, outdoor users, and everyday carry. Purpose-built for unpredictable weather on patrol, in the field, or commuting between sites, the Poseidon stows into its own hand pocket in seconds.

Constructed from 20K/20K waterproof breathable fabric with a DWR C0 coating and fully seam-sealed construction, the Poseidon Jacket delivers serious wet weather performance in a low-profile package. Waterproof coil zippers on the centre front and both hand pockets keep moisture out at every entry point.

Features

• Waterproof-Rated Shell Fabric: 20K/20K waterproof breathable 100% nylon, 3-layer construction with DWR C0 coating. Blocks rain and wind without trapping heat.
• Fully Seam-Sealed Construction: Every seam is sealed to prevent moisture ingress - no gaps, no weak points in wet conditions.
• Packable into Hand Pocket: Self-stows into the left hand pocket for compact carry. Fits easily in a pack, kit bag, or glove box.
• Waterproof Coil Zippers: Centre front and hand pocket zippers are waterproof-rated to keep moisture out where it matters most.
• Three-Panel Hood with Drawcord: Low-profile hood adjusts via drawcord for a secure fit without restricting peripheral vision or movement.
• Articulated Sleeves and Adjustable Cuffs: Sleeve cut follows natural arm movement. Hook-and-loop tabs at the cuff seal out wind and rain at the wrist.
• Storage and Utility: Upper sleeve pocket with flap cover, soft loop platform, and pen slot keeps small essentials accessible without opening the main pockets.
• Drop-Tail Hem: Extended rear hem with internal cord adjustment seals out wind and provides added coverage when moving or seated.
