The main idea is Base Layer > Insulating Layer > Waterproof Layer. This can mean many things and you don't have to spend a ton or have specialty fabrics like breathable goretex. It makes it nicer, yes, but if you're not spending a lot time in the outdoors, don't invest too much.

Base layer: should keep you warm and dry. Cotton is not good for this because it soaks up and holds water. Wool is much better. If you want to use regular clothes, go with fabric blends. Exercise clothes (yoga pants, compression pants, dri shirts) are a really good option here.

Insulating layer: fluffy, quilted, or padded items are good because they have lots of air pockets, which insulates. The air between your base layer and insulating layer will usually be enough. Again wool is good, but on this layer you could go with cotton if you have to.

Outerwear layer: this should be thin and waterproof (windproof is nice too). This is not for warmth but to keep the water off of you. Breathable is really nice because it doesn't trap your body heat in, but it's not required. Many people use thin waterproof windbreakers for this. You could even use a plastic tourist poncho, since you are meeting the requirement of thin and waterproof.

With these layers you can be comfortable in most conditions, opening and closing and removing layers as you go. If you run into trouble, like getting lost in the woods (who knows? it could happen??) you will be much better off with these three layers than someone in a t-shirt and fleece. Outdoors gear is partly for convenience and partly for "what if" - it's worthwhile to remember that. :)

The best trick I can tell you is, dress for what you are ABOUT to do, not what you are DOING. When you start a hike, stop about 10 minutes in and remove some layers, even if you don't feel hot yet. You WILL feel hot soon and this prevents sweat building up in your base layer. When you stop for a break, put your layers back on. You will feel too hot to do this, but your body will actually chill very quickly without them. Think of those little gymnast girls who put on warmup jackets right after they do a routine at the olympics - they aren't cold yet at all, but they know they will cool off quickly and the jacket slows the cooling so it is less extreme on their body. I have sometimes felt too hot to put on a jacket when I stop walking, but have always regretted it later when I start shivering and have to walk quite a while before I warm back up.

Three layers works for ALL parts of the body.. don't forget legs and feet! Gloves and hats and scarves are also useful tools. And maybe most important, bring a lightweight bag you can use to carry all the layers you are taking off and putting on all the time. :D

Finally, a question I can answer.. I don't do a lot of cruising (yet) but I do a lot of hiking in the Pacific Northwest and I've learned all this the hard way. Hope that helps!

I couldn't find a copy of the room service /minibar menu on HALFacts.com, so if anyone has one to share, that would be great.

I will get one in early May, but it will be a while before it's up here, obviously.
