Our best-selling bottle, the Little Big Mouth 21oz Bottle takes a revolutionary design and shrinks it down a bit. It's conveniently shaped and absolutely leak-proof. It has a tight-sealing Big Mouth screw top that's ultra-wide for adding things like ice or your hydration powder of choice. This piece also provides an incredible level of water flow that's up to 50% greater than the competition. Meanwhile, we gave the bottle a flexible, ergonomic design that grips to cages and fits easily in the hand, while the bottle's construction is made from BPA-free plastic that's 100% FDA food-grade approved.

  • Tight-sealing Big Mouth screw top is wide enough for ice cubes and powder drink mix. Wide water channel delivers 50% greater flow than other leading bottles. Plus, improved functional outside grip.
  • Updated MoFlo cap retains the same mechanism and delivers great flow. It's now easier to clean with a flush top and improved grip. 100% leak-free.
  • Easy to grip and more flexible than original Little Big Mouth.
  • Also available in 24oz Big Mouth option.
  • BPA-free plastic made from 100% FDA food-grade materials and printed with non-solvent base (UV cured), CPSC-approved ink and materials.

I like the ankle length, they don’t slip.
Size: Medium, Color: (025) Castlerock / Castlerock / Anthracite
I love these socks, they are thick enough to not be scratchy, thin enough to be cool and breathable.

Fit great
Size: Large, Color: (100) White / White / Halo Gray
Been a couple of months and they seem to be holding up nicely. Real picky about fit of socks and these fit well. They are very thin but very comfortable.

Fit well and stay up
Size: Large, Color: (299) City Khaki / City Khaki / White
They're a little thin, so good mainly for warmer months. But they fit very well and I've not experienced any slippage
