Race Caps (3 Pack) is rated 3.3 out of 5 by 4.
Rated 2 out of 5 by from High-Flow-valve Race Caps The high-flow valve cap does not have a positive cut-off the way the push-pull cap does. This means any time the bottle is sucked or squeezed, fluid will come out, without having to open anything. Conceptually, this is convenient, and the flow rate is awesome. Unfortunately, this can be bad news if you have filled your bottles to put them into your drop bags for ultraruns (or triathlons or adventure events). If the bottles come under any pressure in transport to the aid stations, fluids will spurt out and soak other gear in the drop bag. I like the 18-oz bottles as they give me extra capacity in the Fire-Ball vest, which I love, but I have bought old-style push-pull caps to replace the new style caps.

Rated 5 out of 5 by from Must have These are great accessories - flow rate is awesome, and easy to use. sure, my max distance is full or half, but worked perfectly. I liked so much I bought extras and replaced all of spare bottles. These are made with non-dish wash safe material, so do not ever put them in the dish washer!

Rated 1 out of 5 by from Bad I have the SpeedDraw Plus Insulated Flask, and the replacement race caps do not seal well, they dripping water (all 3).
