ROPE ATTACHMENT/INTERNAL COMPRESSION 90 L
Mutant Nimsdai 90 is equipped with dual under-lid compression straps that can be used to cinch down the load at the top of the pack and/or secure ropes under the lid. The strap can be positioned externally or internally depending on what is required.

1. Begin by locating the female buckle for the strap. It will be visible at the top center of the back panel or it will be found at the top center inside the pack. There is a small pass-through tunnel sewn at the base of the skirt which allows the buckle to be positioned inside or outside as needed.
2. For external use, either with the lid in position or removed, set the buckle to the outside and connect with the webbing strap that is anchored at the top of the front panel.
3. For internal use, primarily for load compression when using the FlapJacket feature, set the female to the inside and connect web strap. Compress and then cinch the drawcord closure before securing the FlapJacket with two front straps normally used to secure the top lid.

GLOVE-FRIENDLY BUCKLES 90 L

INTERNAL HYDRATION SLEEVE 90 L
Place reservoir inside sleeve to help ensure proper pack weight distribution. Clip reservoir to buckled loop to keep upright.
