WHY THIS PRODUCT

Built for Active Surface Use Across Work, School, and Travel

Sentinel360 is made for Surface tablets that spend less time sitting still. Its rigid internal components and flexible outer skin add fitted structure around the body, while the rear control system helps you hold the tablet more securely or position it hands-free. The detachable shoulder strap adds another carrying option for classrooms, service work, travel between rooms, and mobile routines.

CORE ADVANTAGES

Designed Around How You Actually Use It.

Every component has a clear purpose—from protection and control to positioning, storage, privacy, or mobility.

Three-Layer Case System

A structural front frame, hard PC-style inner shell, and durable flexible outer skin combine coverage, shape retention, and reinforced edge support.

360° Rotating Hand Strap

Turn the padded rear strap for portrait or landscape handling and adjust it for a more stable one-handed hold.

Fold-Out Kickstand

Use the integrated rear support for calls, video, lessons, forms, presentations, or reading on a stable surface.

Adjustable Shoulder Strap

The included detachable strap supports shoulder or cross-body carry in portrait or landscape orientation. Check both attachment points before lifting.

Integrated Pen Storage

A fitted pen channel keeps a compatible Surface Pen close to the device without relying on a loose pouch.

No Built-In Screen Film

The product gallery identifies this version as without an integrated screen protector, leaving the Surface display directly accessible for touch and pen input.

REAL-WORLD ROUTINES

A Better Setup for Work, Learning, and Travel.

Field & Service Work

Rotate the hand strap for active forms or inspections, then carry the tablet while keeping both hands available.

Classroom & Family

Improve control for shared use and switch to the kickstand for lessons, calls, streaming, or activities.

Meetings & Travel

Position the Surface for presentations and video calls, then use the removable strap between work areas.

COMPATIBILITY

Choose the Exact Device.

The Surface Pro 4/5/6, Surface Pro 7, Surface Pro X, Surface Go 1, and Surface Go 2/3 options are separate fitted shells. Screen measurement does not guarantee compatibility; match the exact family and generation.

Surface Pro 7Surface Pro 4 5 6Surface Go 2 3 10.5Surface Go 1 10.5Surface Pro X

Selection guidance: Surface Go 1 and Surface Go 2/3 appear as separate 10.5-inch options because fitted openings and dimensions can differ. Surface Pro X is also distinct from similarly sized Surface Pro models. Verify the complete model before ordering.

1. Confirm in Windows

Open Settings › System › About and record the full Surface model or confirm it through Microsoft’s serial-number support.

2. Match the live option

Select the exact Pro, Pro X, or Go grouping before choosing among the available colors.

3. Plan screen protection separately

Because this version does not include a built-in screen film, add a compatible protector separately if that is part of your setup.

INSTALLATION

Fit It Carefully. Test It Completely.

A model-specific accessory works best when alignment and every intended device function are checked before daily use.

Verify device and package

Check the Surface model, selected color, case layers, kickstand, hand strap, and shoulder strap before installation.

Separate the structural frame

Open the front and rear components carefully without bending the tabs or rotating assembly.

Seat the Surface evenly

Align cameras, speakers, charging, buttons, pen channel, and kickstand geometry before securing every edge.

Test the full system

Check touch, pen input, cameras, audio, charging, controls, rear stand, grip rotation, strap clips, and anchors.

PROTECTION & CARE

Use It with Confidence—and Care.

Realistic expectations: This accessory is designed to improve the everyday setup described above, but it cannot eliminate every risk, prevent all damage, or replace careful device handling.

Clean around the display edge and beneath removable case layers to prevent trapped debris. Inspect frame tabs, flexible skin, moving joints, strap stitching, clips, and anchor points. This case is not waterproof and does not make the Surface indestructible.
