Riding a bike in wintry conditions with under-insulated gloves is a recipe for disaster. After all, you have to be able to feel the brakes to use them correctly. For the coldest rides, consider the Louis Garneau LG SuperShield Gloves -- they're Garneau's warmest, combining a lobster claw design with superior protection from the elements. However, they also offer plenty of breathability to ensure proper moisture management.
For a manufacturer, insulating cycling gloves properly requires maximizing warmth while minimizing bulk. The LG SuperShield Gloves accomplish this feat by combining a Drytex 3M lining with varying thicknesses of Thinsulate interlining. Naturally, there's thicker insulation around the fingers and less at the palm. Because that insulation isn't worth much when saturated, the exterior of the gloves is constructed of Garneau's Breathable Twillwave with a fully waterproof and breathable Hipora membrane.
Gloves can become saturated from the inside, too -- that's why Garneau incorporated their Ergo Air concept into these. Strategic ventilation at the palm ensures that sweat has an opportunity to evaporate. An Amara palm with strategically-placed foam padding gives you superior grip and relief from chatter-induced numbness. Reflective piping provides some added visibility. The Garneau LG SuperShield Gloves come in sizes Small through XX-Large and in Black.
