You’ve got your ticket? Check. Your ID? Double check. But without a secure way to store your shampoo and conditioner, your suitcase may be ready for the rinse cycle before you even leave the gate. Fortunately, the season’s best travel kits not only contain a handy mix of first-class travel-size cosmetics; they also eliminate the risk of unearthing liquid luggage at the baggage claim. The Philip B. Travel Kit ($28; philipb.com) includes mini-versions of the brand’s Peppermint and Avocado Shampoo, African Shea Butter Shampoo, Nordic Wood One Step Hair & Body Shampoo, and Deep Conditioning Crème Rinse. Collective Well Being’s Weekend Kit ($15; collectivewellbeing.com) comes with a petite Moisturizing Shampoo, Quick Fix Conditioner, Body Lotion, Body Wash, and Lip Balm. And Earth Therapeutics Jet Lag Bag ($20; earththerapeutics.com) features an Anti-Stress Pillow Mask, Massage Soap, Massage Lotion, Peace Mask, and Mind Repair—goodies that are sure to prove a godsend on the return flight. --Tara Mattarazzo
