3sixteen's standard jeans are 14.5 oz which is a mid weight jean. I personally use 14.5oz denim year round but light weight jeans are around 11-12oz. I believe 3sixteen is planning on releasing a lighter weight jean for the summer months. they're sold in a few stores in canada (lost & found, understudy, the helm, working title). if those aren't near you, self edge offers free shipping worldwide.
