A few other tips related to gloves
-I tend to remove the useless liners inside the gloves when possible and go for wool gloves liners instead
-In some gloves the liners tend to mess up when you remove your hands. To avoid this problem simply sew the liners at the fingertips.
(only for gloves used for commuting and with relatively thin liners or with the use of specific sewing techniques allowing to limit damages, better going for the previous tips which is to remove those liners when possible as it is most of the time a better option)
-Some gloves can fit even though they seems not to when you try them at the store.
+If the fingers of the gloves are too long simply remove the liners and go for 1 or 2 size smaller
+If the leather gloves circumference is 1/2 size too small you can make them fit by soaking them in water for a few minutes and let them dry on your hands
-Some gloves can be cold at the fingertips but be fine anywhere else. In that case there are some solutions
+go to the stores and buy some cheap work gloves or pvc gloves wide enough at the fingertips, cut them and glue or sew them to your gloves fingertips. With leather gloves you can do the same thing with your older leather gloves if you have some
+some glue or just a little bit of silicon at the fingertips can work as well (not advised if you intend to remove your gloves outside because it adds more inertial heat which means more heat necessary to warm back more material)
-If you got cold thumbs when riding a cheap clear plastic film attached with clear tape in front of your thumbs on the handlebar can help a lot even better if you decide to make bar mitts with clear plastic film
-To make gloves as warm as mitts without losing dexterity inherent to gloves some easyseat sheepskin cover attached to the back of the gloves with shoe laces can be pretty efficient. A bunch of old socks cut at the middle of the foot length and sewed together as well
-Putting gloves on a few minutes before going outside can help making the commute more comfy
-A little bit colder fingertips but more dexterity is sometimes better than warmer fingertips but less dexterity when you know than dexterity will be needed during the ride (to repair a flat for instance) as it avoids the need to remove the gloves and lose all the warmth inside
-I've got more dexterity vs warmth with leather gloves than gloves using synthetics especially those synthetic gloves with more loft at the fingertips but all leather gloves are not equal - cowhide is usually thicker. Taking care of the leather could help making them a little bit warmer.
- a good way to know if some gloves insulate better than others is to compare them with one different system in each hand at the same time. The icepack test where you grab an icepack with both hands and see which one takes more time to let the cold go through is an easy way to know which one insulate the best. Doesn't say much about wind protection though.
-when gloves are stretchable it usually means to me that a trade off has been made between warmth and more fit. It also means potential blood flow problems at the fingertips
- because hands are probably as different as people on earth (length of each finger especially index vs ring vs pinky, hands and fingers circumferences especially thumb vs other 4 fingers, right hand vs left hand) the only true way to know if those fit is to try them (at the store)
