CamelBak Classic Bottle Cap Accessories Graphite-733 Immediately

I regularly use my BPA-free bottles (Nalgene and Camelbak) for making tea at work. The loop-top cap that came with the wide-mouth Nalgenes would stretch with the heat and if you held the bottle by the loop, it would sometimes slip off the bottle (the loop, not the cap -- if this makes sense). This lid fits both bottles, and doesn't expand with heat, so you can grab it by the loop and go. Get more detail about CamelBak Classic Bottle Cap Accessories Graphite-733.
