What Our Gearhead(R) Experts Are Saying:"The built-in measuring scale on the HSC 250 Bottle is a feature I didn't know I needed until I started using it on race day. Being able to glance down and know exactly how much I've taken in keeps my nutrition plan on track without any guesswork, and the soft HDPE material squeezes easily even when I'm in an aero position."Staying on a nutrition plan mid-race means knowing exactly how much you've consumed, and the Profile Design HSC 250 Bottle makes that easy. The built-in measuring scale lets riders track intake at a glance, while the translucent grey finish keeps contents visible throughout the ride. Soft, BPA-free HDPE construction is easy to squeeze from an aero position, and the 290ml capacity is sized for top tube flask use where compact dimensions matter.
