Daniel Neilson tests out a diverse range of baselayers. On test Bergans Soleie Ultralight 150g Baselayer

This Bergans 100 per cent merino baselayer is another favourite in the bunch. It’s a very light merino fabric and would be good pretty much year round. It’s a perfect backpacking top as the merino won’t smell after a few days use. It has flat-locked seams, and is comfortable, only with a slight roughness that comes with merino.
