Not selling a Camelback (?!?), but I have a spare club tri singlet + shorty (both in the nice water-repellent "Askin" fabric) that I am not using. Size S, so would be OK for a small lady (too small for me, no kidding!). Never worn in training or racing, 100% new.
Anyone interested, drop me an email.
Cheers,
Seb
