I've put alot of work over the years into figuring out a small/light/effective glove system for early to mid season. Use the same system for late season, but then in late season augmented with Kuiu super down glassing mittens as needed.
Men's Versaliner - black | Outdoor Research The OR Versaliner Gloves are fleece gloves with zippers on back that hold waterproof/windproof/breathable shells that can be taken on and off as needed. I seam sealed the seams on the shells with McNett SeamGrip to make them totally watertight. Very light and very flexible to conditions. Windy? Put on the shells? Rainy? Put on the shells.
I wanted a very light, thin liner glove that had touchscreen compatibility and one that would be thin enought to fit into my OR Versaliner without adding too much bulk such that it would be hard to get the gloved hand in and out of the Versaliner Glove. This so I could quickly take a hand out of the Versaliner, do some fine motor skills stuff keeping my hands somewhat warm with the liners. It makes a big difference to keep the fingers warm and working. The best liner I've found to fit inside the OR Versaliner Glove is the Montane Power Dry Glove (
Montane Power Dry Glove | UK | Ultralight Outdoor Gear ). Had to order from the UK last I checked. Not available in the states. Thin and tight fitting enough that you can do most tasks requiring fine motor movements with them on and keep some warmth in the hands. Plus can use touch screen very well with them.
With these and both layers of the Versaliner Glove on, you've got a pretty warm system. If I need more than these, it's the Kuiu Super Down Glassing Mits.
