I'm looking at replacing my baselayer top to get it under 4 oz. I was wondering: Is this possible with merino wool? I use microweight Smartwool bottom baselayer pants at around 5.15 oz. Not sure what a microweight top would weigh. Maybe around 5 oz?
Additionally, are there superlight gloves for summer mountains where expected lows are 30s-40s? My MH Powerstretch gloves weigh 1.34 oz but have sprung several holes.
