My black Gil’s have a 3 tag. I think it’s the size. Mine are elastic (no velcro), and they’re more of a dark brown than black. I got mine from Necalliboxing and I notice the Velcro strap on their version is wider with a larger GIL badge. Been using them since fall 2021 and love them. Quality they’ll last forever. At first I had to get used to the leather seam inside the glove that you’ll feel along your fingertips. I bought my brother the Necalli professional heavy bag gloves which are great too. A toss up but I prefer the matte leather finish on the GILs. I also noticed I didn’t have to squeeze my fist in the Necallis as much; I agree with your comment about needing to squeeze your fist in the GIL’s but they’ve gradually broken in and is less of an issue years later. The leather still looks brand new as does the stitching.
