My guide pans are 3-4 years old I think so they may have updated the design and fabric but...
Guide pants are right in between the attack and tiburon. a bit lighter and breezier material than the attacks but block wind and cold better than tiburons. Guides are looser fit than the attacks about the same as tiburon too. As mentioned, the attacks have hip vents which is a BIG plus IMO.
Both attacks and guides pick and pull fairly easier. No real rips in either. Of the pair of guide pats and pair of attacks I have that are roughly the same vintage, I think the guides are holding up better but in fairness, the attacks have probably been worn a little more.
they are all great and I am sure will work fine. Given a choice I would probably prefer the attacks over the guides for general hunting pants from warm to cool weather. For hot, dry weather I would go tiburons.
As to other pants, I have a pair of Kanabs that I have never been crazy about so I never dropped the $$$ to see if the obsidian would be better.
