I bought this Zest Tank in a small for cycling, jogging as I like the fly back. I know some people like the lycra in the product however it made it too big for me. The material tends to gape at the underarms. The tank is very long - Icebreaker seems to be making their tanks longer than the other tops I have - not a good fit for me. Maybe an extra-small would have been better.
"Brilliant for any hot weather activities."
So lightweight you'll barely know you're wearing it, this top's flattering seam lines and longer length will highlight your figure as it gently skims the body. Icebreaker's 150 weight merino wool is a delight to wear; wicks better than polyester, never really feels wet, dries incredibly swiftly and virtually chafe-proof. The racerback cut closely matches the lines of most sports bras, the armholes provide plenty of room for swimmer lats and the higher neck line offers a bit of modesty, if that's your thing. Not as much reflective as its predecessor, but a better overall fit and finish. This one is a winner for road or trail, training or racing.
