I Put a Rain Cover on My Bass Case and Biked 20 Minutes in the Rain

This article is written by Toru Hoshino, a jazz bassist and instructor based in Japan who teaches online lessons to students worldwide. In this article, he puts a rain cover on his bass case and bikes through the rain for 20 minutes to see if it actually works.

For this one, I put a rain cover on my bass case and biked for 20 minutes in the rain, to test whether the case stayed dry.

Spoiler: the bass came out completely fine. Here’s the full process, from putting the cover on to arriving at the destination.

Putting the Rain Cover On

Getting set up:

It’s generously sized, so it covers the case with plenty of room to spare: 385(w) x 1220(H) x 70(D) mm.

And off I go.

20 Minutes of Biking in the Rain — Arrived at the Studio

Made it to the studio. The outside is, naturally, soaked.

And on the inside…

Completely dry. Great job, rain cover.

Once You’re Done With It

Once you’re done using it:

Roll it up,

and it packs down small.

Small enough to fit right into your case.

Noah’sark Rain Coat NRC-Bass (Rain Cover for Electric Bass Cases)

The “Noah’sark Rain Coat” was built to protect your precious instrument from rain — the natural enemy of carrying a guitar or bass around. It’s designed to slip entirely over a gig bag or hard case and is easy to put on and take off. There’s a waterproof zipper section right where the case handle is, so you can pull the handle through and carry the case as normal. If you’re using it with the “Noah’sark Semi Hard Case,” you can even wear it on your back with the double shoulder strap while the cover is still on. When you’re not using it, it folds down small enough to tuck right into your case’s pocket. Bass size (BSH): 385(w) x 1220(H) x 70(D) mm

Sudden rain catches you off guard precisely because you never have a rain cover on hand for it. Well worth having, just to protect an instrument and case you care about.

Update, July 2025

Since writing this, I’ve also tried out a few rain covers from other manufacturers, including some newer brands. All of them had solid water resistance and felt genuinely good to use.

I’ve also covered how they feel in actual use on video, if you’re curious.

Keeping your gear dry is one problem solved — knowing exactly what to work on once you sit down to actually practice is a different one, and that’s exactly where a teacher helps.
