Use the A3SB Saddle Bag to add about 3 liters capacity to Eberlestock packs. Use them for additional gear storage, or when paired with Eberlestock hydration bladders, they are a great way to externally mount hydration on a pack so that the bladder is easily accessible. The Saddle Bag is perfectly sized for the WXP3L hydration unit.
There are two ways to attach the A3SB to a pack: they mount best on 6-row tall Padlock webbing panels using the Saddle Bags integrated clip system, but can be mounted in a variety of other places using a tether attachment.
The A3SB is particularly recommended for the G2, GS05, H2, and F3F packs, but will work with most others..
