Aldi   Winter Gloves   Euro 14.95

The gloves were cheap and normally Aldi has good products at low prices. Normally, because these gloves are just crap, and I should have returned them immediately, but now it is too late. The gloves don't keep warm and the artificial leather is much too hard, one really has to use force to bend the fingers of the gloves.
Conclusion: Cheap crap, absolutely not recommended.

Hein Gericke   Winter Gloves   Euro 19.95

These gloves were relatively cheap too and the promising statement of up to -30C was tempting. They are padded very thickly, which makes them bulky and one needs some strength to bend the padded fingers of the gloves. The -30C probably means the the material won't break up to this temperature, as they are not as warm as expected.
Conclusion: Another mispurchase, absolutely not recommended.

Cycle Gear   Alpinestar   Winter Gloves   $69.95

Not really cheap, but I don't have good experience with cheap gloves (see above). They keep quite warm, if it is really cold I use an additional inner glove (see below). The gloves are waterproof, even after many hours in the rain, and one doesn't get a cramp just from bending the fingers. One has a good sense with these gloves and can easily operate the brake and clutch.
Conclusion: Absolutely recommended.

These rain gloves get worn over the normal gloves and are absolutely waterproof, but they are so bulky that it can come to dangerous situations if one can't reach the brake lever because the glove is in the way.
Conclusion: I can't recommend them, they are too dangerous for me, I rather have wet fingers.

Polo   Winter Inner Gloves   Euro 17.95

Quite thin inner gloves that keep surprisingly warm. But they are not really cheap.
Conclusion: Absolutely recommended.

Polo   Winter Inner Gloves   Euro 19.95

Quite thin inner gloves, they too keep quite warm, and they are not really cheap either.
Conclusion: Absolutely recommended.
