How to use Elastic cord kit. Think, plan, measure, cut, burn, thread and tie! Easy as that. Elastic cord attachment thingies are simple, affordable modifications you can do to almost any piece of load carrying gear.
The Hatka 12L was conceived as a part of a special military load carrying system, which needed a small daypack that could easily be attached to a larger backpack. One really awesome way to do this is to attach the Hatka to the side compression straps using PALS-mounted SR buckles.
Our packs are made with ITW Classic or 2M WB series side-release (SR) buckles. For this quick-attach trick we recommend using 2M WB SR PALS-mount female buckles (as shown here, and yes we sell these). You will need four of these to securely attach the Hatka 12L to the back of your Jääkäri M, L (shown here) or XL.
Note that ITW Classic and 2M WB series side-release buckles ARE NOT COMPATIBLE with ITW GT (GhillieTEX) series side-release buckles! So even if a ITW GT QASM looks like a 2M WB SR PALS-mount buckle these are not cross-compatible. If you want to use ITW GTSR buckles you need to swap out the buckles on your main packs side compression straps too to make this work.
