When I switched my morning coffee for yerba mate, I got obsessed with perfecting my mate setup. There's a lot of options, and a lot of ways to make mate.
I noticed there's a real gap between "buy any gourd on Amazon" and "buy the right gourd and bombilla for how you actually drink mate," and that gap is where most people end up with a moldy gourd three weeks in, or a bombilla that clogs every other sip.
TL,DR: Unless you're really committed to the most traditional way, I'd avoid the mold possibility and get a non-porous, washable gourd.
I've been through a few setups at this point. Here's what I'd actually tell a friend to buy, broken down by material, size, and care, so you don't have to learn it the slow way. And if you're looking for where to start on the yerba itself, not just the gear, here are the 10 bags I'd point a friend toward.

Calabash (dried gourd). This is the traditional option, and for good reason. It's what most Argentine and Uruguayan mate drinkers grow up with. A calabash gourd needs to be "cured" before first use (soaked, scraped, dried) and it needs to be treated like a living material, not a mug. That means it can mold if you don't dry it fully between uses. It also builds a patina over time that mellows the flavor, which is part of why people get attached to one gourd for years.
Here's my recommended calabash gourd from Amazon:
Stainless Steel. Clean, easy, indestructible. An easy go to. Here's the one i'd choose that is CLASSY and has a stainless steel inside.
Ceramic. This is another where I'd point most beginners, and it's genuinely not a downgrade. Ceramic gourds don't absorb moisture, don't mold, and clean in seconds with regular soap and water. You lose the flavor patina that calabash develops over time, but you also lose the anxiety of checking your gourd for mold every morning.

An alpaca silver bombilla looks great and needs regular polishing to stay that way.
Stainless steel. I'd focus on bombillas with lots of small holes. The spring version gets clogged so fast. They are easiest to clean as well. Try this one which comes with two.
Alpaca silver. Beautiful, traditional, and the one that shows up in every "aesthetic mate setup" photo. It tarnishes, though, and needs actual polishing to stay looking like the photos. If you like maintaining nice things, this is a fun ritual. If you just want to drink your mate, it's one more chore. Here's one with a good price.
Bamboo. Lightweight and pleasant to drink from, but the filter holes are usually wider, which means more loose yerba making it into your mouth. Fine for coarser yerba, frustrating for finely ground stuff. Here's an example. Honestly, skip it.
Small gourds (roughly 3-5 oz) are built for the traditional style: pack it, drink it down, refill with hot water several times through the morning. Larger gourds (6 oz and up) are better if you're the type who wants one big fill and doesn't want to think about it again. If you're brewing your yerba mate less bitter by using more water per fill, a slightly larger gourd gives you more room to work with before it gets watery.
Refilling all session is a lot easier with a good thermos next to you. I break down the one I would buy, plus the lid swap that makes pouring clean, in Blog: Best Thermos for Drinking Yerba Mate All Day.

If you've read my post on mold showing up in a mate gourd, you already know the short version: moisture trapped in a porous material is the entire problem. Calabash and wood gourds need to dry fully, upside down, in open air, between uses. Never seal one in a cabinet or bag while it's even slightly damp. Glass and ceramic sidestep this issue almost entirely, which is the real argument for starting there if mold is what's kept you from committing to a gourd in the first place.
Bombillas need a simple rinse after every use and an occasional deep clean with a bottle brush to clear the filter holes. If your yerba is on the finer, dustier side, look for organic yerba mate cut a little coarser. It clogs bombillas far less often than the dusty commercial stuff.
Not everyone wants the traditional ritual, and that's fine. If you'd rather brew mate like a strong tea or coffee, I've covered two solid alternatives: yerba mate in an AeroPress and yerba mate in a French press.
Both skip the bombilla altogether and give you a cleaner cup with less to clean.
Whichever way you go, the gourd and bombilla you pick will shape whether mate becomes a daily habit or a thing that molds in your cabinet. Start simple, keep it dry, and the rest takes care of itself.
