Gloves- http://www.lifemojo.com/shop/reinforced ... ck-7387657
These turned out to be quite nice and economical.
This is quite popular and versatile.
Air Mask - no idea,but dont purchase the Neo Mask from BOTS or online.They say its for cyclists but its quite suffocating.Give a shout if you find something good.Last heard of a good mask at Wheelsport.
Buy from lifemojo.com and playgroundonline.com if you don't have decathlon membership.
Btw how much did Sporterra cost you?
