Super long length but quality fabric
Size: 28, Color: Army Green
Fits more like skinny jeans rather than slim fit. It’s a size 28 so my waist fits fine but the length is super long for no reason. I decided to keep it due to the fabric material feeling. I fold the bottom of the pants to make it look for fit. I’m 5’4.

Buying more pairs.
Size: 36, Color: Purple
True to fit and extremely comfy. Even tho the title says mens, it’s designed like a womens when it comes to the pockets. Not deep pockets. If you want a tight fit go a size smaller, if you want a baggy fit go size bigger. Color is how you see it in photos.

“Elegant, Practical, and the Perfect Gift .
Color: Black Cambridge
It’s one of those pieces that feels both classic and modern at the same time, perfect for any occasion.
The removable ID window is a very useful feature, especially for someone who needs to show their ID frequently.
The interior design is also very well thought out—everything stays organized and easy to access. I like that it combines functionality with style, which isn’t always easy to find. It definitely feels like a durable and well-made product.
It’s a gift that truly feels worth it and special. I would definitely recommend it to anyone looking for a stylish, practical, and high-quality wallet.

If you're looking for a high-capacity wallet, look no further!
Here's the breakdown on slots: It's a bifold with a passcase kind of flap. Standard bill holder with no divider. On the left, it has 3 slots to hold cards horizontally, and 2 slots to hold cards vertically, for a total of 5 slots. Right is the same design, 5 slots. The passcase-like flap has a clear cutout for an ID on the left side, and on the right side, it has 3 slots to hold cards vertically. We're up to 13 slots. There are also 3 pockets in the wallet when the passcase-like flap is moved to the left side of the wallet: One on the right behind the credit cards, one on the left behind the credit cards, and one in the passcase-like flap under the flap's credit cards. That's 13 cards, and 3 pockets that can store insurance cards, business cards, or even 3 or 4 stacked credit cards in each flap. One could theoretically cram 25 credit cards in this wallet. Realistically though, this will hold 13 cards, as those pockets will likely be holding other personal effects.
As for the quality, it's pretty great. The material is leather, and the cloth in the bill holder is diagonally-striped burgundy and navy cloth. In the middle of the wallet, with the pass-case like flap to the left, there is vertically-striped cloth; the color is burgundy surrounding one stripe of navy, with an ivory border between them. It looks very well-made. I also absolutely that some card slots are horizontal and some are vertical, as I can organize my cards in groups (ie: my 2 credit cards from one bank go vertically on left, my 5 from another hog the entire right side, my 3 debit cards rest in the passcase-like flap's card slots). In terms of being able to organize stuff, this wallet is a masterpiece. An absolute, ultimate, card-hungry masterpiece. I've had other wallets with less slots and had to resort to double-stacking credit cards into slots in order to carry them, which only led to premature wear and faster replacement of those wallets (not to mention the slots getting stretched to the point that cards were no longer secure and would fall out if the wallet was opened and shook). This is why I am writing such a raving review. For anyone that has many credit cards, those FICO score hypermiler types (as for myself, I'm up to 7 credit cards now), this wallet is a masterpiece.
With 13 cards, 2 IDs resting in the clear window on the passcase-like flap, about 10 bills, and about 5 paper cards in the pockets, my wallet measures about 1.25" thick at the thickest point... It might even be 1.5" thick, as I'm just making a visual estimation. It's a fat, fat wallet, but only because it's so stuffed with things I otherwise couldn't carry if I resorted to a less spacious wallet. I normally would be bugged by this lump that is noticeably larger than other wallets, but 2 days into owning this, I find it kind of reassuring, as I know this puppy is full of every credit card, bank card, ID, and insurance card I own. It feels good to sit down and think that I can fit every card I own in it perfectly. This wallet is for people who have a lot to carry and want to carry it all. If the desire to carry everything outweighs the inconvenience of the wallet's width, it's a great wallet.
When it comes to wallets, there are two people in this world: those that don't need this many card slots and would dislike the thickness of this wallet; and people who could use most of these slots and would appreciate being able to do so, when other wallets leave them wanting for space. I'd recommend this for the latter, and for the former, I'd recommend getting a wallet with less capacity and less size. For the latter, I think your search ends right here. It's such a good wallet for capacity that I just wrote 3 pages on it.
