V3.7 ROSINFILTER BAGS
Flow-channel geometry protected by U.S. Pat. 11,511,465 (additional patents pending), with a seamless front panel and inside-out construction for cleaner release. The pre-snipped wide-mouth opening loads fast, no funnel needed.
This is what a bag that holds gets you: a clean, steady run straight into the jar. Seam integrity is yield.
Flow-channel geometry protected by U.S. Pat. 11,511,465 (additional patents pending), with a seamless front panel. The inside-out construction cuts internal seams, and the pre-snipped wide-mouth opening loads fast.

V3.7 Rosin Bags
Recommended for your setup
Picks based on the micron and pack size you chose. One tap adds them to your cart.
Patent-Pending Design
Flow-channel geometry with a seamless front panel keeps resin moving.
Inside-Out Construction
The flipped design cuts internal seams for cleaner release.
Wide Mouth Opening
Pre-snipped flaps make a wide mouth, so you skip the funnel.
Flow Control Technology
Patent No. 11,511,465. Pairs with KWÄD, FLUID, and AIR presses.
Part of a Closed Path
The truncated-cone mesh and O-ring flow seal direct resin down toward the drain. The bag is one component of the closed collection path (functionally closed, not sealed or hermetic). See the science → Pair it with the pre-folded parchment pouch, the next stage of the path.
A flow path, not just a screen.
Under pressure the bag — not the press — sets how fast and how cleanly your extract gets out. The V3.7 geometry is built around that: seams out of the flow path, no bottom stitch, and directional channels that stay open under load.

PICK YOUR
MICRON
- Best forPremium, top-shelf material
- OutputLowest — the cleanest press
The finest mesh in the set — it passes the least source material for the cleanest possible press, trading a little yield for purity.
- Best forFine, high-grade material
- OutputLow — very clean
A very fine mesh for high-grade material where clarity still comes first.
- Best forPremium material (most popular)
- OutputMedium, balanced
The everyday premium micron — a balanced mesh most shops reach for first.
- Best forGeneral pressing
- OutputHigher — more yield
The most open mesh in the set — it opens up for more output when yield matters.
One shop,
the whole line
Wash, press, dry, and resupply — every stage built and supported by the same Lake Forest team. Spec it as a system, not a pile of parts.
