No Gi

What is the difference between regular BJJ class and no Gi BJJ class?  Simple: you wear a Gi in the regular class and you don’t in the no Gi class.

The more complex difference is, of course, do the two classes “feel” different?  For me, yes – they feel very different.  With the Gi, there is stuff to grip.  There is friction.  When you get a hold of something, can hang on to it.  With no Gi, stuff slips and slides this way and that – it feels faster.

Do both.  Do both to feel the interesting difference.  Do both for practicality.  Sometimes people are wearing jackets and pants.  Sometimes they are wearing a flimsy t-shirt and shorts.
