What Is Foundry?

Built to explore the boundaries of imagination, Foundry is our forge for special fabrications, unique colorways, and product experiments.


How Does Foundry Work?

Research the product and make a purchasing decision.  Keep an eye on the status bar and note the project end date.  Some projects may have minimum quantity thresholds, and many will have maximum units limited by fabric or trim availability.

Once you have secured your order, we will send you an order confirmation email and ensure your order is part of the batch.  When the product is within 2-3 weeks of delivery, we will send you another email alerting you that the project is completing production and about to ship.  Once the product has shipped, you will receive a final email with shipment notification and tracking information. Once your product arrives, use it and share your adventure with us using #tripleaughtdesign.


How Long Does It Take To Get My Foundry Purchase?

Each project shows the estimated shipping timeframe. While occasionally some items may ship immediately, most projects will have a 6 to 8 week delay. Once the project ends and production begins, estimated shipping dates will be published. From time to time, issues in production may crop up and we'll let you know if we need to adjust the estimated shipping date.


When Am I Billed?

Your card will be charged upon checkout.

Will Foundry Products Be Available In Retail?

Returns or exchanges may find their way to retail occasionally.


How Do Returns Work?

Just like normal. Please see our returns policy here.

  • Accessible

    Protected from the main compartment's contents and padded for comfort against your back, an ambidextrous zippered pocket on the back panel protects flat equipment such as tablets or laptops up to 13”.

    A generous front admin pocket offers multiple storage options, including an integrated admin panel, keeping everyday carry items organized and accessible.

    An external zippered pocket opening from the bottom of the pack bellows upward into the main body, providing segregated storage for dirty items, such as gym attire or shoes, or quick access items like bike locks and medical supplies.

    A zippered accessory pocket on the top of the pack provides convenient access to frequently used items, such as sunglasses or snacks.

    A flat, centered welt pocket conceals 3 rows of single-column 1” webbing, compatible with small accessories such as Pharos Markers, bike lights, or even our S1 and S2 sheaths.

  • Organized
    • Inspired by the intermodal container system, the Helix (HX) attachment system provides a lightweight, modular solution for configuring storage platforms. Helix supports standardized, interconnecting modules which can be configured as fixed or railed storage, a multitude of compression and attachment options, and paneled storage configurations.

    • The main compartment includes two rows of Helix attachment points along the back panel for use with a wide range of organizing accessories, including, Control Panels, and Transport Sleeves. Additional webbing loops at the top and bottom pair with our Compression Strap Kit to secure bulky loads, and provide a blank canvas for configuration options.

  • Resilient

    The Axiom 18 utilizes advanced materials to create a lightweight but resilient carry system. Originally developed as a high-performance sailcloth, the shell is a durable, weather-resistant ripstop nylon hydrostatically laminated with a structurally reinforcing scrim.
