Last year I started using MacWet's in the cold season. I wanted to find a glove that was suitable for office dwelling wimps like me with rubbish circulation, who aren't really cut out for the cold weather!
I've tried a few different brands before but they were either so thick that you lost feel on the reins, or just didn't provide any warmth or grip. I then tried the MacWet 'Climatec' glove, which was brilliant! I was dubious at first as I couldn't see how such a thin glove would offer much warmth, but they are actually wind proof, water resistant, and have a fleece lined back to the glove. The Aquatec fabric they're made from responds to moisture and climate change - hence MacWet's are renowned for being the 'all grip no slip' gloves.
Because they aren't bulky not normal winter gloves, you still get a great feel down the rein, and you can still manage buckles and bridles without a problem.
I recently tried a pair of the Micromesh gloves; they're more for your warmer weather conditions. They're also made from Aquatec, so you still get the comfort and grip of the climatec's, but the mesh part is designed to aid circulation of airflow around your hand, and as they say on the website, "giving maximum grip, sensitivity, feel and comfort, no matter how wet or humid." Unfortunately I got to test that this week - I was schooling Ruby and the heavens opened. I couldn't finish because she had not done enough, so we persevered. I kid you not I looked like a drowned rat, with just a cotton shirt, jodhpurs, rain pouring off the peak of my hat - but my MacWet's kept all the moisture away from my hand, and my grip on the rein remained exactly the same as before. They look really smart, fit like a second skin, and the material feels really luxurious.
I've used mine for all disciplines - xc, sj, dressage, and always schooling at home or hacking. They're really versatile and comfortable, and hands down (excuse the pun) the best glove I've used. They've already proven a great buy, and come highly recommended.
