Lightweight, just 38Gms and not too expensive like the carbon ones.
Holds the bottle securely.
Never used the band, but seems like a welcome feature.
Small con, it can be very tight on some bottles (I use Polar bottles), scratching the same slightly.
Fantastic and upgraded Bottle cum reserve tube holder, Made in Taiwan, seems to be good product. Birzman quality stamp is an added advantage
this was for my black gravel bike -
1. it blended perfectly with the color of the bike
2. the utility underneath the cage to carry additional spares
Added velcro attachment at bottom is useful.
