Keiko Gis come in a variety of options for design, color, weave pattern and weight. We actually have one of the lightest gis on the market at just 1.95 lbs (Ultra Light Gi with Rip Stop Pants Size: A0). The weight of the Gi will differ depending on the Design and Pants chosen as the Cotton Pants tend to weight more than the Rip Stop Pants.
Generally, in order of lightest to heaviest, our Gis weigh as follows:
ULTRA LIGHT GI > SLIM FIT GI >SUMMER GI > CAMO GI > BALANCE GI > LIMITED SERIES GI > GOLD WEAVE GI
Most Keiko Gis are IBJJF Approved for competitions. The only ones that are not, are the ones that are not within the accepted colors such as the Camo Gi or our specialty color gis such as the Navy, Red, etc... but YES our White, Royal Blue and Black Gis are IBJJF Approved.
