Underlabs underwear from Kmart Belmont. They have been on clearance for a while at $10 for a 2-pack, from $20 (they have large and XL left, I think). I also got the Underlabs 2-pack socks for $5 from Kmart East Vic Park. They are doubly cleared from $10 to $7 to $5. Belmont also have them, in all sizes I think.
