They are made from jersey and are not entirely knit like some wool gloves. I didn't find the seams bulky. Apparently people tolerate cold differently. I would consider them suitable for temperatures of forty degrees or brief outdoor times in the thirties. UPDATE: Worn out on the miniature in three months. I have short nails and didn't wear them most of the time (our winter calls for warmer gloves/mittens) so I think this pair wasn't very durable and downgraded.
