Every time I find an online discussion forum for martial arts, I inevitably seem to find the endless discussion about gear. The general consensus seems to be that if you don't "invest" in the best gear (and everyone has their own preference and only theirs is correct), you cannot be a good / serious martial artist.
I fell for that nonsense when I was starting out. Ooh, Shureido or Tokaido? $300 tonfa? $600 sai?
Fortunately, I couldn't afford any of that. Did I envy it? Yes! That gear is sweet! But is it necessary?
Maybe if you're serious about competition, you want every edge to make you look your best, and there's no doubt that high end gear is, well, great to use as well as see. But that's not me. I competed for awhile, did err, ok-ish, and lost interest as I got older.
All I really need is a durable gi that fits and moves well, and weapons and protective gear that protects me and doesn't fall apart. Big money is just money I don't need to spend.
Over the years, I've found that the basic middleweight Century brushed cotton gi with elastic waistband works well for me. It lasts about three years before I wear it out. In the summer, I like the Tiger Claw diamond weave lightweight gi, also with elastic waistband. They seem to last forever and they're cheap.
For belts, Amazon. I like thinner material for an obi anyway, they stay tied and lay flat. I've never worn one out; I've ended up buying 3 because gaining and losing weight.
Sparring gear? Any cheap foam stuff. I experimented with some 'better' gear. It just costs more, that's all.
I bought a Shock Doctor cup 15 years ago and it's still fine. Wedding tackle intact.
Weapons? Amazon bamboo bo, cheap sai, etc. Beater bo seem to be far superior to me when I can afford to throw them away after they start to splinter.
Now maybe that makes me a less serious martial artist. My obi is not embroidered with my name in Kanji or my dan rank. Sigh. Oh well. I'll somehow live with the shame.
I guess all I'm saying is by all means, buy whatever gear you like. But if you can't afford or don't want a $300 gi, don't feel badly. Kit doesn't make your punches harder or your kicks faster. You can be a serious martial artist without the high end gear.
