For those who are the real hardcore travelers, these new products from Nikwax should be of interest. Those on the road who wear the same shirt multiple times before washing and some other articles of clothing know it can get pretty stinky! But this Nikwax Basewash Gel ($6.65) cuts odors, speeds drying, and keeps base layers clean and fresh. Another product is Tech Wash Gel ($11.65) for waterproof clothing and their Waterproofing Wax ($7) for leather adds water repellency, reduces water absorption, and maintains breathability to all types of smooth leather. The best part about these products is that they come in convenient travel sizes so they can be carried in hand luggage.
