Pls Help Me Identify My Ride

hi there,

been a lurker of this site for quite sometime.

have my first mtb setup as recommended by a saleslady :thinking:

can you help me identify the frame? hindi ko kasi mahanap sa giant site.

how will i know it's size (s, m, l)? sa gulong na ba i verify if 26er or 27.5?
