Underarm flotation device

Improving Comfort, Mobility, and Operational Performance

The challenge

Traditional life preserver designs can introduce operational challenges that affect comfort, mobility, and overall equipment integration. In demanding environments where users rely on multiple pieces of mission-critical gear, flotation systems must provide buoyancy without compromising functionality or freedom of movement.

This challenge can:

Interfere with helmet clearance and head movement
Restrict neck range of motion during critical tasks
Add unnecessary bulk around the upper body
Increase the burden of equipment already carried by the user

The switlik solution

Switlik developed the Underarm Flotation Device to relocate buoyancy where it supports the user without interfering with movement. By positioning flotation beneath the arms rather than concentrating it around the chest and neck, the system improves comfort, reduces bulk, and allows greater freedom of movement while maintaining reliable flotation performance.

Operational context

Military aviation operations
Maritime security missions
Helicopter operations
Extended-duration wear environments

Key advantages

Reduced Bulk
Underarm flotation minimizes obstruction across the chest and upper body.
Improved Mobility
Allows for greater freedom of movement during mission activities.
Enhanced Comfort
Reduces pressure on the neck and shoulders during extended wear.
Better Equipment Integration
Works more naturally alongside helmets, harnesses, and other mission equipment.
