Focus Sash question

Focus Sash is the "Endure" item, right? I'm wondering how it works in 2v2 battle, would I be able to endure both hits in case someone gangs up on my Sash carrying Pokemon?

For example, I have a Pikachu with Focus Sash and a Bulbasaur playing against my brother's Charmander and Squirtle:

Turn 1:
- Bro's Charmander uses Ember against my Pikachu.
* Pikachu has 2 / 20 HP left.
- My Pikachu uses Agility.
- Bro's Squirtle uses Surf against my Pikachu.

Will my Pikachu still endure Squirtle's Surf, obviously staying at 1 HP? Or is a Focus Sash useless in 2v2 battles?

im pretty sure it only endures one hit that'd drop it to 1 HP. if its hit after using it, its dead so far as i know.

Focus Sash only works as an endure when you get hit at 100% HP

Example

-Bro's Torterra used earthquake on pikachu
-it"s 2x effetive
-Pikachu holds on using its focus sash.

A focus sash can only activate if a move begins to hit you while you have full HP. It does not protect you for the entire turn in 2v2 battles if you have max HP.

In your situation, pikachu will not survive with 1 HP. But, if the ember would've knocked it out, it would've survived with 1HP, only to be knocked out by surf.

So it can be much more easy dealt with in double battles.

It does not protect you for the entire turn in 2v2 battles if you have max HP.

Alright, this is what I needed to know. Thank you very much!

I know how a Focus Sash works, but didn't know if it was for the entire turn, or just for a single hit in double battles. Thanks again, guys!
