The Bontrager B1 base layer is a lightweight, fast drying base layer that's ideal for warmer weather.
This has become my default base layer over the past few weeks. When everything is washed and ready to go, it's the one I reach for first for warm rides.
This summer base layer provides excellent ventilation and moisture transfer to keep you comfortable on even the hottest rides.
Craft make some great base layers. Their winter base layers are far and away my favourites for the off-season and this lightweight option is another top performer.
When I say 'lightweight', at 56g this is almost floaty light. It's made from polyester with just a little (5%) Lycra in there to add some extra stretch. It's a mesh structure with large, round dimples that let loads of air through.
