Those hotel sheets may look clean, but you're wise to be wary. Best bet: Pack a soft, luxurious silk DreamSack in your bag (it stuffs into its own 8 x 4 x 1" pouch). 100% silk keeps you cool and dry in the summer, and warm when the temperature drops. DreamSack has a built-in pocket for a pillow, and a side opening that closes with tab fasteners. Machine washable; quick drying. Imported. Available in Honey, Sage or Lilac.
