My god... Tree and bush disguises. Ingenious.
I agree - he should have 3 - 4 suits on display in the cave, as prototype - i do believe the basis of each suit should be the 'typical' bat suit in that it is a modernised 'spandex' style suit - with added kevlar, utility belt, cape and cowl.
Think MOS zod body suit, a similar style which is used for sports, fencing, racing etc, as the material is durable/can't be split by various blades and flame resistant.
#1 suit - standard Batman suit, light, flame resistant, flexible - based off a ninja/fencing costume with added elements. For when Batman is out observing, investigating, handling small crime.
#2 suit - extra armour (think Arkham games) for when he knows he will be in a situation that calls for it - breaking up a drugs bust, going into a hostage situation etc.
#3 suit - kryptonian inspired super suit (think iron man prototype) that perhaps has powered up arms for super grip and punches and a chest plate extra strong.
Weapons/gadgets - batterang a must, grappler and smoke bombs
