Second Best Bifold I’ve Owned
Color: Black
I’ve gone through a lot of wallets over the years (cheap ones, expensive ones, slim cardholders, you name it), and this Timberland bifold with the attached flip pocket is easily the best all-around wallet I’ve ever carried.
The leather is excellent: full-grain, soft right out of the box, and it’s aged beautifully in just a few months with a rich patina that actually looks better with every scratch and scuff. Build quality is top-notch: tight, even stitching, no loose threads, and the edges are finished cleanly. Four months of daily front-pocket carry and it still looks practically new.
Layout is perfect for me. Six card slots plus the two slip pockets behind them handle everything I need (10 cards + a few folded bills) without getting bulky. The attached flip ID window is a game-changer; I keep my driver’s license and work badge there and can show either in seconds without opening the wallet. Cash fits easily in the full-length bill compartment.
It’s genuinely slim for a traditional leather bifold, sits comfortably in both front and back pockets, and never feels like a brick. The embossed Timberland logo is subtle and classy.
At this point I can’t imagine switching to anything else. It’s durable, functional, looks sharp, and was a fraction of the price of some “luxury” wallets that didn’t last half as long. If you want a classic leather bifold that actually delivers, this is it. 100% recommended; already planning to buy another as a backup.

Rugged Timberland Quality—The Best Bifold for "Double ID" Needs
Color: Black (Sportz)
Design & Capacity:
I’ve been using this wallet for two weeks, and it’s a powerhouse for organization. The attached flip pocket is a game-changer for me because I have to carry both a driver's license and a work security badge. The two ID windows let me show both without digging through card slots.
Genuine Leather: Looks and smells premium; will likely weather nicely with age.
The Slimness Factor:
Timberland calls this a "slimfold," and while it is thinner than a traditional trifold, the flip-out pocket does add some depth. With 6 cards and 5 bills, it measures about 0.75 inches thick. It fits comfortably in my back pocket, but it might be a bit much for a front-pocket-only user.

Wanting a standard nice wallet. Get this
Color: Black, Color: Black
Your standard wallet. Nothing to complain about. Does what it’s supposed to and I have no complaints. The fit is amazing. Holds at least 17 20 dollar bills and over. Durability is also amazing to say the least. Doesn’t rip at all, with a lot of money in it. Its thickness ties in with how much money you can fit in it, so I won’t go into that category. Overall what you see is what you get. A standard, nice, durable wallet that sticks into your pants.

High Quality but with tiny holes
Color: Navy (Blix)
There were two very tine holes on top of the wallet unfortunately. Otherwise the product nice snd high quality. I like it a lot but unfortunately I returned it back. That is the reason I gave 4 starts.
