For those of us who feel like we're wearing the world's tightest biking shorts when we put on anything close to "slim fit", the regular fit on these shorts is awesome. I wear slim fit for nice occasions and meeting with clients, but the supertubes are perfect for day-to-day wear and working, riding my townie around town, etc. I even wore them fly-fishing a few times. I'm impressed by how durable all my Quiksilver shorts have been too. They have been worn a ton and have held up incredible well.
