Clothing (for warm-weather).

Choosing what gear to pack can be quite fun or rather anxiety-laden, depending on your personality. I’ll break down the kind of clothing I’ve packed for solo travel in warm-weather as a starting point to help you get thinking. You can always go lighter or heavier depending on your situation. This is from a man’s perspective, so ladies feel free to add your expertise in the comments below!

2-3 pair of riding knicks. These can be washed nightly and cycled through easily (no pun intended). A necessity for most when considering comfort.  

2 pair of underwear. Hiking underwear with microbial and quick drying properties are a good investment.

3-4 pair of socks. Can also be cycled through, but best to have an extra pair because you may be changing them more frequently than other items. I trust wool as the most comfortable in both hot and cold conditions. 

2 pair of shorts. In some countries, riding knicks may be looked at with distaste by conservative locals so be ready to throw on a pair of shorts when necessary. Plenty of pockets and zippers (preferably seam-sealed) are great. Zip-off pants that convert to shorts are also good for their versatility. I like to have a pair of ¾ length shorts, which cover a bit more skin for a temple visit, etc. Be sure the shorts feel comfortable while riding, hiking, and just plain chilling out. Any clothes that can serve multiple purposes are best.

2 short-sleeve riding jerseys. Pick your favorites! I still pack a grey one made by Gore that has good heat distribution and makes me look and feel a bit like Solid Snake. You wouldn’t be a biker without at least one! Alternately, you can dress like Ratboy.

1 short-sleeve sport jersey. Any jersey with similar comfort and wicking/cooling properties that can double for cycling and soccer, hiking, chilling out, etc.

1 long-sleeve wool jersey. Wool is great for a range of weather/temperature conditions, and can also be used for a variety of activities. Pick a good, lightweight one from your local outdoor store.

Detachable sleeves. These come in options for both hot and cool conditions. Under the hot summer sun, the right sleeves will keep you cooler and less sun-baked.

1 pair of casual pants. Whether it’s a club or an invitation to a local home, have a pair of something with you that reminds you that you aren’t always a sweaty, stinking hulk dressing for efficiency’s sake. You'll find things to do in town other than tune your derailleurs. Weight be damned, I pack a pair of well-fitting jeans.

1 casual shirt. Similar thinking as above. I suggest dropping a bit of cash on a shirt that's highly technical for outdoor sports but also designed to look good with rolled up sleeves in the evening. Be sure to color coordinate with your casual pants, yo!

Helmet. You'll need one.

Hats/caps. There will be times when a helmet isn't necessary on the trail or when hoofing around. Broad-brimmed, with a neck covering or without… it’s your choice which to bring. The broad-brimmed hat below also has a micro mosquito net attached to it-- there were times when I have been thankful to have this tiny item. A cap with a bill will be helpful when riding in the rain. A running/riding cap will keep your head cool and soak up sweat from your eyes. (see below).

Gloves. Your hands are one of three contact points with your bike, and best to keep protected. Fingerless or fingered is a personal choice and dependent on your riding intentions.

Rain gear. I travel with an OR Helium rain jacket that's very light and packable with full waterproofing (OR also provides a lifetime warranty on their products). There are many similar types of jackets on the market. I don’t recommend anything heavier unless you really anticipate constant downpours. Waterproof shorts have not been necessary for me in warm conditions. A hat (waterproof or not) with a bill works to keep the rain out of your eyes.

Buff. A buff is one of the top items for me to bring on any adventure because of its many uses. It protects you from dusty roads and other pollutants, provides insulation at night, and can filter out particulate matter from dirty water, just to name a few. If you are really cool (or lose your buff), try a shemagh instead. Cambodia is a great place to collect scarves for this purpose.

Shoes. Shoes take up space and have significant weight, so this can be a tough decision. It is also a decision related to what kind of pedals you bring with your bike.

For maximum versatility, go with clipless pedals, cleated cycling MTB shoes, and a second pair of trekking/active shoes. This allows you efficiency when cycling and something to wear off the bike. Road cycling shoes won't allow you much once off the bike, while MTB shoes will, including a number of designs specifically for riding and trekking as you may be doing.

For maximum simplicity, use flat pedals with or without toe clips along with a single do-it-all pair of shoes. Shoes with a stiff sole will work well; back in the old days a pair of Adidas Sambas kept you looking good while keeping cadence.

Remember you'll need a pair of shoes in any case to wear to the bar, play soccer in, climb a hill, etc. so be sure you've covered all your bases.

Armor. This depends more on your intentions for racing or playing on your bike, so consider if shin, knee, elbow guards or more are necessary.
