The Impulse has a lot of great features. The flat bottom means it stands up instead of constantly falling over. Zipper less main entry is quiet. The quick attach is magnetic. There is loads of internal pockets, everything has a place and this eliminates the coon pawing around trying to find the tool you need at the time. Just imagine you're bowhunting and have a buck cruising through 100 yards out, it's November 7th. You need your grunt tube, it's either in it's spot or you have to dig. Not with this pack. Impulse is a great fit, feel, and will help you be successful.
