Keeps you cool when it's warm and warm when it's cool!
I have worn the Tech T Lite (140 weight) in August in Georgia - yep, you read that correctly. I have donned wool in the hottest and most humid month in the South. I also always layer several long-sleeve pieces to ski (and have yet to be cold or too hot), hike (in all kinds of weather) and lounge around the house. In fact, I am currently wearing Icebreaker pants (discontinued unfortunately) and a new Icebreaker 260-weight Long-sleeve Crewe I received as a Christmas gift.
Avoid Sticker Shock (plus tips on Clothing Care)
You may find the products to be a little pricey (the Tech-T Lite is around $55), but I can assure you they are worth it. Just make sure that you take of them properly and they should last a long time. Icebreaker articles can be washed in the washer. I wash mine on the cold cycle, usually on delicate - although I don't think this is necessary - and let them air dry. Occasionally, a piece or two has found its way into the dryer but ultimately survived in tact.
My Testimony
I found out about Icebreaker five years ago while living in New Zealand. I arrived unprepared for a hiking trip and the guide suggested I buy Icebreaker long underwear. Since that faithful purchase, I have never been too cold or too hot while wearing my long johns - and this is coming from a girl who used to shiver at the mention of snow! After several weeks of hiking success and a 21-day Outward Bound course, I purchased a bit more to get me through the ski season and then a few more pieces before leaving the country. Although my Icebreaker wardrobe has expanded a good bit, I still have and wear most of the original pieces - many have survived three seasons of working on the slopes in addition to other multi-adventurous uses. Icebreaker is currently available at Changes In Latitude Travel Store and other outdoor retailers.
