Product description
If you use your GoPro Hero 13 Black day to day, you’ll quickly learn that “light protection” isn’t really protection. This K&F CONCEPT kit leans into the practical stuff: a silicone sleeve case, battery-side cover, screen and lens protection, plus a lanyard to help reduce the chances of misplacing the camera.
It’s not a rugged “drop-rated” case for heavy abuse, but it is thoughtfully designed for everyday scuffs, minor knocks and travel carry. The battery-side cover is also made so you can access the battery without fully removing everything—handy when you’re charging or swapping batteries mid-trip.
The essentials
This is a silicone sleeve accessories kit specifically made for a GoPro Hero 13 Black. Over the camera you get a silicone sleeve for a snug, soft-touch outer layer, and on the front you get protective pieces for both the screen and the lens area.
On top of that, the kit includes: - A battery side cover designed with a cut-out/bored section for battery access - Screen protectors (2) - Lens protectors (2) - A loss-prevention lanyard that can attach to the silicone sleeve

If your priority is keeping everyday contact points covered—rather than adding bulk—this type of set makes a lot of sense.
What stands out in day-to-day use
The biggest “why this kit” detail is the way it handles battery access. The battery compartment area of the protective cover is made hollow/so you can take the battery in and out while the silicone sleeve is still in place. There’s also a reserved opening in the battery cover area to make charging easier.


That’s the kind of detail you notice in real use. For example: imagine you’re packing after a session, slide the battery out for charging, and you don’t have to peel the whole sleeve off first. On a busy travel day, that saves faff.
Key takeaways on protection

The silicone sleeve is described as being 1.8mm thick—moderately soft and also firm enough to provide protection. So it should help with minor bumps and everyday handling.
For the screen and lens protection, the kit uses tempered glass protectors described as thin at 0.3mm, with a high light transmission approach and a sensitive feel. They’re also listed with 9H hardness and resistance to scratches and tears/abrasion.
Worth noting: screen and lens protectors help a lot with scratches, but they aren’t a guarantee against everything a serious impact can do. The kit is more about keeping things covered than replacing a full protective housing.
Tech details

- Protection focus: daily 360° coverage as described, including screen and lens protectors

Who it’s for (and who should be cautious)


It makes sense if you want a simple accessories kit that protects the parts you touch and see most—screen and lens—while adding a soft outer layer around the camera.
It may not suit you if you need maximum protection against severe drops, or if your setup demands a more substantial protective case design. Silicone sleeves are good for everyday scuffs, but if you regularly expect heavy impacts, you might find this approach falls short.
Getting the most from it
This kit is straightforward, and the sleeve is described as easy to install. Still, with any screen/lens protector, take your time with alignment and surface prep so it sits properly.

Also, the lanyard is a nice inclusion for everyday carry—especially if you’re often moving between locations or clipping your gear onto a bag strap. That’s a small thing, but it can be the difference between “brief worry” and “lost camera”.
Should you buy it?
Buy it if you’ve got a GoPro Hero 13 Black and you want an accessories kit that focuses on daily protection: a silicone sleeve case, battery side cover that still allows battery removal and charging access, plus screen and lens tempered glass protectors and a lanyard.
Skip it (or consider a more substantial protective approach) if you expect the camera to take more serious knocks than typical travel and day-to-day handling, or if you’re specifically after a bulky, all-out protective housing rather than a lightweight sleeve-and-protectors setup.
