I wouldn't really want to climb the West side of Pants Pass. That would be a hard task.
A note on it's East side though. The chute you took down is indeed Pants Pass but there is a way you can cheat and take an easier route.
Yeah, from Pants Pass drop down Gaiter Gully to Socks Saddle then over to Bandana Basin and take Tee-Shirt Traverse heading up Raincoat Ridge to Poncho Peak. Much easier and you get the whole outfit.
