Smatree Hard EVA Sleeve Case for 14 in Lenovo ThinkBook and Yoga

In this review of the Smatree Hard EVA Protective Sleeve Case (Model X8040) the bottom line is simple: this sleeve is for owners of 14 in Lenovo ThinkBook 14s Yoga Gen 3 or Gen 2 and 14 in Lenovo Yoga 9i who want a compact, sturdy protective cover that slides into a backpack without adding bulk. The case's single biggest selling point is its anti-shock padding combined with a hard EVA shell, which delivers reliable protection against knocks and scratches while keeping a slim profile for daily carry.

Key Features

• Exact compatibility: Internal dimensions of 32.4 x 21.9 x 2.7 cm mean the sleeve is tailored to fit 14 in ThinkBook 14s Yoga Gen 3, Gen 2 and Yoga 9i models snugly.
• Anti-shock construction: The hard EVA exterior plus an upgraded shock resistant padding layer protects the laptop from inadvertent collision and daily bumps.
• Water resistance: Durable 1600d nylon on the outside obstructs light splashes and makes the sleeve washable when it gets dirty.
• Soft interior: Interior lining is pleasantly soft to avoid scratches on the laptop surface during insertion and removal.
• Compact styling: A unique diamond pattern on the surface gives the sleeve a fashion-forward look without adding unnecessary bulk.
• Lightweight portability: The slim profile lets the sleeve fit inside backpacks or suitcases while protecting the device.

Who It's For

This sleeve is best for owners of the specified 14 in Lenovo ThinkBook or Yoga laptops who prioritize protection in a low-profile package. Commuters, students, and travelers who carry their laptop inside a larger bag will appreciate the anti-shock padding and water-resistant nylon shell.

It is less suitable for users who need room for chargers, large adapters, or multiple accessories inside the same sleeve, or for those with laptops larger than the listed internal dimensions. Buyers with bulkier docks, thick protective skins, or different 14 in models should verify measurements before purchasing.

Frequently Asked Questions

Will this sleeve fit a 14 in laptop with a thin protective skin?
The internal dimensions are 32.4 x 21.9 x 2.7 cm, so thin skins may fit but thicker skins or cases could make the fit tight.

Is the exterior waterproof?
The 1600d nylon exterior is water resistant and obstructs light splashes, but it is not fully submersible waterproof.

Can it hold a charger or accessories?
The sleeve is designed primarily for the laptop and has a slim profile, so it does not provide significant extra room for chargers or large accessories.
