Available in long or short-sleeved versions, Altura's Thermocool base layer has radically improved my default perception of man made, mid priced technical wear.
Not only does the temperature-regulating fabric decide whether to retain or disperse, it also ensures a faultlessly smooth and confidence inspiring profile beneath snug fitting race jerseys. Admittedly even the best polyester/nylon/Lycra mixes can't quite pip natural fibres to the post when it comes to outright comfort but then again, they're less likely to emerge from an accidental boil wash fitting the neighbour's Siamese cat.
Basically the idea is to keep you cool as you warm up but retain warmth when the air temperature drops and this is as significant when blistering along Pyrenean mountain passes in the height of July as soldiering through the Surrey slush. The downside of base layers made from synthetic fibres is that they can get a bit whiffy here though antibacterial yarn helps prevent things turning funky should you all pile in for a mid ride meal at the Dog and Duck.
Altura employ a form of body mapping technology; which tailors material density according to where you sweat most-thinner beneath the arms and sides, thicker around the shoulders, chest and back area to protect these regions from chill, resulting in a mesh- but- not- quite look. Flat locked seams prevent unsightly branding while going unnoticed against the skin. Aided by our old friend Lycra, the clever cut ensures optimum comfort when stretched out on the drops, or more extreme cross-country mountain bike cockpits. To be frank, this all comes together rather well.
Watching vampire flicks on the telly, strapped to the trainer and with the oil fired heating going strong, it took a fair while for things to get noticeably soggy- especially beneath the arms and around the lower back but never to the stage where it was matted against the skin and the wicking comes to the rescue pretty quickly, leaving me relatively dry after forty-five minutes. Out in the real world, worn beneath other polyester layers, moisture trafficking has been remarkably good in varying temperatures without discomfort or unsavoury odours.
Probably the most comfortable man-made base layer I have used to date
