Opt for an olive camouflage bomber jacket and charcoal jeans to pull together an interesting and modern casual ensemble. For something more on the off-duty end to finish off your outfit, complete this ensemble with olive canvas high top sneakers. As you can see here, it's very easy to look sharp and stay warm when chillier days are here, all thanks to looks like this one. Perfect if you're scouting for some seriously inspiring style for 30-year-old guys.
