Use the A3SB Saddle Bag to add about 3 liters capacity to our packs. Use them for additional gear storage, or when paired with our hydration bladders, they're a great way to externally mount hydration on a pack so that the bladder is easily accessible. The Saddle Bag is perfectly sized for our 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 Bag's integrated clip system, but can be mounted in a variety of other places using a tether attachment.
The A3SB is particularly recommended for our G2, GS05, H2, and F3F packs, but will work with most others.
Dimensions: 17"h x 5"w x 3"d
Weight: 10 oz
Vevy well constructed
The bag works great,i use it for my 2 liter hydration blatter on my F1.
They say it will hold a 3 liter blatter but i dont really see how cause the 2 liter fills it up pretty tight.
This fits an MSR dromedery bladder perfectly, transforming it into the hydration pack you need for a Mainframe.
Great -- works well and is durable
