DuraShield Pro - Rugged Protection for Garmin Fenix 8 & Descent Mk3i
Avontic Garmin Protection Series
Snap-On Protective Case + Separate Tempered Glass Screen Cover
For Selected Garmin Fenix 8 Sizes and Descent Mk3i 51mm
Cover the Display. Keep Garmin Controls Accessible.
DuraShield Pro combines a model-specific snap-on outer case with a separate tempered glass screen cover to help reduce direct contact with everyday scratches, scuffs, light bumps, and flat surfaces. The raised, instrument-inspired bezel adds rugged visual detail while preserving access to the watch buttons, rear sensors, band connection, and charging area.
A Garmin case cannot be selected by diameter alone. Watches with the same 47mm or 51mm diameter can have different button positions, bezel shapes, sensors, speakers, microphones, and case thickness. Select the exact named watch and size shown in the product options.
Why DuraShield Pro
A screen protector helps cover the display but leaves the bezel and watch body exposed. A bumper case protects the outer frame but may leave the glass vulnerable. DuraShield Pro combines both pieces so the display surface, raised bezel, corners, and outer watch housing receive additional everyday coverage.
The bold bezel markings also change the visual character of the watch, giving compatible Garmin models a more tactical, instrument-inspired appearance without replacing the original watch body or band.
Designed for daily Garmin wear
Snap-On Protective Outer Case
Adds a fitted physical layer around the watch bezel, outer frame, and corners to help reduce direct contact with common surfaces.
Separate Tempered Glass Cover
Installs directly over the clean display to help reduce exposure to scratches, fingerprints, and flat-surface contact.
Raised Bezel Profile
The raised perimeter helps keep the screen area from resting directly against a flat surface when the watch is placed face-down.
Model-Specific Button Openings
The correct variant is shaped to preserve access to the watch buttons and other exterior features without requiring case removal for normal use.
Rear Sensor and Charging Access
The rear remains open so the heart-rate sensor area and Garmin charging connection can continue to function normally.
Eight Finish Options
Choose Black Orange, Titanium Steel Blue, Black Green, Black Red, Silver Black, Transparent, Black Blue, or Orange Green.

Compatibility comes first

Do not order by “size class” alone
Do not assume compatibility with Fenix 6, Fenix 7, Epix, Enduro, Quatix, Tactix, another Descent size, or any Garmin that merely shares the same diameter. Those watches require explicit model verification.
Installation and first-use check
1. Verify the Exact Watch
Confirm the full Garmin model, case size, display/version when applicable, and selected finish.
2. Clean and Apply the Glass
Clean and dry the display completely, align the tempered glass, and press it down evenly.
3. Snap On the Case
Align the buttons and exterior openings, then press the case into place gradually without forcing it.
4. Test Every Function
Check all buttons, touchscreen where applicable, sensors, charging, band movement, speaker, microphone, and flashlight openings.
What’s included

Protection and care
DuraShield Pro helps reduce exposure to common scratches, scuffs, light bumps, and surface contact but cannot prevent every type of damage. It does not increase the Garmin watch’s water or dive rating. After sweat, rain, swimming, saltwater, chlorine, sunscreen, or trail use, remove trapped moisture and debris and dry the watch, case, and screen edges completely.
