I fished in -4c on sunday ,wearing half a pair of simmsn fingerless with another half pair of orvis fingerless ,both fleece ,and both slightly loose fitting .
with a pre leaving home dose of Norwegian formula hand cream ,hands stayed reasonably warm ,the simms hand possibly slightly warmer ,then they are ten years younger .
Just cant get on with the neoprene ones ,never felt good on me , so as not to be brandist , i have been happy with some snobee fingerless fleece ones but the Orvis and simms being loose fitting seem to have the edge .
