What hydration reservoirs sold at REI are compatible with the REI Flash 22 pack. Description says it has an internal sleeve to hold a hydration reservoir (sold separately); includes a port to route the sip tube over either shoulder. Just need to know what fits best. TC
@TimberlineCruiser Thanks for reaching out!
The REI Co-op Flash 22 will fit up to a 3 Liter hydration bladder. Hopefully this helps!
Will all models work? E.g. Camelbak, Hydrapak, Gregory all work equally well?
@KAS Thanks for reaching out!
Yes, all models of water bladder will work with the REI Co-op Flash 22 pack.
Thanks!
