Open Sea Topsider Bifold LT Review: A Comprehensive Look at Michael Bluth’s Masterpiece

Today, we’re diving into a detailed review of the Open Sea Topsider Bifold LT. This wallet represents Michael Bluth’s 18th design and is touted as the culmination of all his experience in crafting exceptional wallets including the Topsider, Houbei, and Topsider Bifold. I’ve had the pleasure of examining three versions of the Topsider Bifold LT: one I purchased myself and two that Michael generously sent over. Each has unique features, and I’ll be covering all the details and nuances in this review.

First Impressions and Options

Upon first glance, the Open Sea Topsider Bifold LT impresses with its craftsmanship and variety. You can choose from numerous leather and thread color combinations, making each wallet a personalized accessory. The ones I have showcase different options, including a classic single-color design and a more vibrant green and black combo. Each wallet comes packaged in a charming cotton bag, adding to the premium feel.

Design and Build Quality

Michael Bluth has clearly poured his heart and soul into this wallet, and it shows. The Topsider Bifold LT is made in the USA from full-grain Botero leather sourced from the Conceria Walpier tannery in Italy. This high-quality leather promises durability and a rich feel. The wallet’s dimensions are 3.7 x 3 x 0.3 inches, and it weighs just 1.2 ounces (35 grams), making it exceptionally lightweight and compact.

Key Features

  • Security Flap: A distinctive feature is the security flap that tucks in to protect your cash and cards.
  • External Card Slot: Holds up to two cards. This slot is optional, depending on your preference when ordering.
  • Internal Card Slots: Two internal slits for cards, designed to minimize bulk.
  • Cash Slot: Can hold cash folded once or wrapped, fitting neatly inside the wallet.


One of the standout aspects of the Topsider Bifold LT is its functionality. It can accommodate up to 10 cards and full cash, either folded once or used as a wrap. I demonstrated both methods, and the wallet handled them effortlessly. The design cleverly reduces bulk while maintaining usability, making it a practical choice for everyday use.

Unique Design Elements

Michael’s signature style is evident in the unique sewing pattern and round punches on the back, which prevent the leather from tearing. The slanted flap design ensures a perfect fit when closed, adding to the wallet’s sleek look. The subtle brand stamp is another nice touch, providing a minimalist aesthetic that I appreciate.
