A good man may be hard to find, but good men's gym bags are all over the place. The hard part is picking your favorite from all the variety. Narrow your choice by choosing one to suit your sports. Do you need a racquet pocket? Water bottle holders? A wet/dry bag? Light, or heavyweight? And unless you also carry a purse, remember you'll need a place to stow your keys and wallet. Most men's gym bags have that covered.
If you're into water sports or you're a Sweaty Eddie, look for waterproof gym bag materials and mesh breathability so your gym bag can air out even as you carry it. In a closed bag, your stuff starts to stink in a hurry, and moisture can be hard on cloth, so protect your gear and your friendships.
Any chance you'll use it for light travel and weekend getaways? Add a removable shoulder strap and easy-access outside pockets for documents, cell phone, and something to read while waiting for your cab or your tee time. A firm bottom isn't just good for people--a reinforced liner protects your stuff and the bag itself from the tough realities of an airport, subway or gym.
Strength adds weight. Some guys prefer to travel light, and there's nothing lighter than a classic duffle. Drop gear in, draw the string and sling it.
If you're riding your bike or motorcycle to the gym, consider a backpack-type men's gym bag that stays stable and off your hip. While you're at it, satisfy your sense of style. Bags come with your favorite sports logos and in endless colors and shapes. Some men love real leather; European bags offer such soft luxury with no-fuss simplicity in classic, durable elegance.
So consider your sport and your personality.
