Choose long-sleeved shirts and pants for winter weather. Pack wool or thick cotton socks. Gloves or mittens will keep your hands from freezing. A wool hat is cozy and warm if you have a coat without a hood. Ear muffs are easy to lose so use a more practical head covering like a hat with ear flaps. Fleece scarves or balaclava hats can protect your neck from the chill. Waterproof boots will keep your feet from the damp. Roll socks up and tuck these into your boots for compact packing. Encase the boots in plastic bags to keep your clothes dry and clean.
Pack thinner clothes for warmer weather. Short-sleeved and sleeveless shirts are good choices for both men and women. Skirts and dresses made from thin cotton or linen are appropriate for women. Shorts and capris make hot weather more bearable but pack at least one pair of long pants for the evening cool. A shawl or light jacket can provide immediate warmth when the sun sets. Pack swimsuits or trunks. Be aware however, in some countries, swimming wear is inappropriate as it reveals too much of the body.
Choose thin cotton underwear to pack for summer climates. Bear in mind, some destinations may not provide acceptable medication solutions to any conditions that spring up. As a result, in warm climates, do not choose underwear that is too tight or made from polyester because these can facilitate the growth of yeast infections. Skip wearing underwear at night if you are prone to this condition. Pack long underwear for winter climates to provide another layer under your clothes.
Pack all medicine in the original containers and bring the prescriptions from your doctor. If you are going into an area where there are few amenities, pack an extra pair of spectacles or contact lenses as well as your eye prescription. Keep the contact numbers of your home doctor with your medicine or eyewear. Do not pack medicine, eyewear or other assistive devices into your luggage but take these with your carry-ons.
Pack compact versions of toothpaste, toothbrushes and floss that you ordinarily use at home. As of 2010, most airlines will not permit containers holding anything more than 4 oz. Sunscreen that doubles as a moisturizer will give you more room in your kit for other toiletries. Pack compact brushes and combs for your hair. Miniature versions of name brand toiletries are often available for travelers. Pack toiletries in plastic sandwich bags to prevent spills getting into luggage.
If you are traveling internationally, bring your passport. Bring your cash in the local currency of your destination, travelers' checks and credit cards. Pack these in a money belt or a money pouch that you can tuck under your clothes.
Pack diapers and wipes for a baby. Sun protection is important for a baby's sensitive skin, so pack a hat to shade his face. Pack any clothes that are season-appropriate for the child. Pack wipe clean bibs to keep your child clean. A baby sling and your baby's blanket are useful extras for carrying and comfort.
