1. Flow Kimonos brand has a good gi for $79.99 at the time of this post.  To get this deal, you’ll need to visit their website and signup for their newsletter to receive the discount link.  Sometimes they have it available when you first visit their site as well.  I have used two of their gis over the past 2 years and they have both performed well.
  2. Elite Sports BJJ gi is another low cost option currently listed around $60 on Amazon.  I have reviewed and been using one of these gis for the past few years and it has done well.
