If you're wearing Explorer's Clothing, you are Unarmored. If you look at the Armor table, you will see there's a Category called Unarmored. Wearing anything from that Category = Unarmored, and will use your Unarmored Proficiency.
Explorer's Clothing gives you a +0 item bonus to AC, with a Dexterity Cap of +5.
If, while wearing Explorer's Clothing, you use Animal Skin, you will instead have an Item Bonus of +2 and a Dexterity Cap of +3. At 13th Level, it is instead +3 Item Bonus and Dexterity Cap of +3.
If you're Unarmored, you can put runes on yourself with either Explorer's Clothing, the mystic armor spell or bands of force. That's why the Animal Skin feat says:
"This item bonus to AC is cumulative with armor potency runes on your explorer's clothing, mystic armor, and bands of force."

Yes it will be a normal light/medium armor AC bonus where when default base item bonus (without potency runes) + capped dex bonus is equal to 5.
Only after level 13 when the barbarian get the greater juggernaut is when it will improve the base item bonus to +3 giving a +6 when sum with capped dex reaching the same AC of a heavy armor.
IMO this feat is a good candidate to a rebalance errata because many other classes got "heavy armor" AC way earlier specially after remaster:
So IMO this +3 AC could come earlier at level 7 when barbarian gets juggernaut instead of get it with greater juggernaut.

It's actually much better than that. It gives you expert prof in unarmored at level 6 instead of level 13. That's actually a level earlier than the Champion, 5 levels ahead of Fighter.
So at level 6 you get AC of 25 instead of 23. The +1 at 13 is to throw you a bone once the benefit of the ability goes away.

Yeah, Animal Skin doesn't really need a buff.
If we compare it with Invulnerable Rager at level 8, the Animal Skin Barbarian has an AC of 28 while the Invulnerable Rager has an AC of 27. They equalise at 13th. So for 7 levels (assuming the Animal Barbarian takes Animal Skin at the earliest possible level) the Animal is better than the Invulnerable Rager, and at all other times they're equal.
Also, the Animal Barbarian has 0 downsides compared to other options. No Bulk, no speed reduction, no have-to-be-on-ground restrictions, no action tax, etc. Most of these are minor, but still worth pointing out.
