Full details →Who the LifeStraw Go Stainless Steel Filtered Water Bottle 24 oz is for
Buy it if: Trekkers and travellers drawing from streams or taps of uncertain bacterial quality.
Avoid it if: Anyone treating groundwater for heavy metals, arsenic or salinity -- filtration does not address any of those.
Who the Alaska Bear Natural Silk Sleep Mask Contour is for
Buy it if: Light sleepers, shift workers, and anyone who finds a flat mask presses on the eyes.
Avoid it if: Anyone who needs total blackout -- a small gap at the nose bridge is normal on any contoured mask.
