Smatree 17.3 in Laptop Sleeve for HP 17 Series - Super Corner

In this review the Smatree 17.3 in Laptop Sleeve (Model E815) is evaluated for owners of large HP laptops who want a slim, protective carry option. The sleeve's single biggest selling point is its patented Super Corner impact protection, which delivers targeted shock absorption without turning a sleeve into a bulky case. For anyone carrying a 17.3 in HP OMEN, Envy, OmniBook or HP 470 G9/G10, this sleeve aims to balance slim profile, water resistance and accessory storage into one practical package.

Key Features

• Precise fit: Internal dimensions of 42.5 x 27.5 x 2.5 cm provide a snug fit for many 17.3 in HP laptops and reduce internal movement during transport.
• Super Corner protection: Patented corner impact design cushions drops and bumps where laptops are most vulnerable without adding unnecessary bulk to the sleeve.
• Water-resistant fabric: Made from durable 300D polyester, the sleeve resists light moisture and splashes to protect the laptop exterior.
• Accessory organization: An included accessory pocket stores chargers, cables and small peripherals so essentials stay together and easy to access.
• Travel friendly: Integrated luggage strap keeps the sleeve secure on rolling luggage and simplifies airport transit.

Who It's For

This sleeve is designed primarily for owners of 17.3 in HP models such as OMEN 17t/17, Envy 17t/17, HP 17/17t/17z and HP 470 G9/G10 who want a slim solution with targeted protection. It suits commuters and travelers who prefer a sleeve inside a larger backpack or briefcase and those who value water-resistant material and an accessory pocket.

It may be less ideal for users who need heavy all-around drop protection, hard-shell security, or those whose laptop dimensions fall outside the listed internal measurements; customers reporting fit issues should carefully verify device size before purchase.

Pros & Cons

Pros

• Excellent corner shock protection from the Super Corner design that deflects impact where it matters most.
• Durable, water-resistant 300D polyester fabric that shields against light moisture and daily wear.
• Convenient accessory pocket and luggage strap help keep cables and travel organized.
• Slim, tailored profile that slides into larger bags without taking much space.

Cons

• Fit is mixed for some users; the sleeve is snug and may be tight for laptops that are slightly larger than the stated internal dimensions.
• Not a hard-shell case, so it does not replace a rigid protector for very rough handling.
