After a number of internal studies, Hyperlite has decided to remove the metal grommets from the weep holes of their packs. This product may ship with or without the grommet as they are phased out from Hyperlite's inventory.
The grommets were not an essential feature to the weep holes of the pack. Hyperlite has determined there is no physical function of these grommets and they have been merely for aesthetic purposes. Their design and production team has developed a consistent method of precision drilling the holes in the fabric. The heat generated from the friction from this process will seal the edges of the weep holes and eliminate the chance of the fabric fraying. This will now make the holes just as strong as when constructed with grommets.
