Is this a good pack?

[Meridian]

I'm in the process of getting a REP-63 contract, and I wanted to include rucking in my training program. I've never purchased any sort of pack before, and I just wanted to make sure that I get something that will do the job. Are either of these packs good for training? http://www.amazon.com/Olive-Genuine-...3984715&sr=8-1 and http://www.amazon.com/2275-LARGE-DIG...ref=pd_sbs_a_9. Thanks for the advice.
