Other than appearance, what is different between these and ExOfficio's other gloves by the same name:

The only difference appears to be that these are also marked as "stretch" and "lightweight", but (going by the amazon page for the ones linked above) they weigh the same (1.6 oz), and both are listed as "Touchscreen-capable stretch fleece gloves", so presumably the cheaper ones can stretch as well.
What makes these worth almost double?
