6 Best Wool Sacks for Sheep Shearing

Shearing day ends with two things: naked, happy sheep and a mountain of wool on the skirting table. That pile of fleece represents a year’s worth of work, and how you handle it next determines its value. The humble wool sack is more than just a bag; it’s the first step in preserving the quality of your clip.

Why Jute Burlap Sacks Are a Shearing Day Staple

There’s a reason you see old photos of shearers stuffing fleece into big, tan-colored sacks. Jute burlap is the traditional choice because it breathes. Wool can hold a surprising amount of moisture even on a dry day, and sealing it in a non-breathable bag is a recipe for mold and mildew.

Burlap allows that moisture to escape, protecting the fleece during storage and transport. It’s tough enough to be dragged across a barn floor and can hold the fleece from several sheep without tearing. For moving wool from the shearing floor to the skirting table or for short-term storage in a dry barn, it’s a reliable workhorse.

The major drawback, and it’s a big one, is vegetable matter (VM) contamination. The sack itself sheds small fibers into your clean wool. Mills penalize heavily for this because those jute fibers don’t take dye the same way wool does, creating flaws in the final product. So while it’s classic, it’s not always the best choice for high-value fleeces destined for a commercial mill.

Premier 1 Supplies Nylon Sacks for Durability

Nylon wool sacks are the modern answer to burlap’s contamination problem. These slick, woven plastic bags are incredibly tough and, most importantly, they don’t shed. A clean fleece put into a nylon sack comes out a clean fleece.

Their durability is a huge asset on a small farm. You can reuse them for years, washing them out between seasons. Unlike burlap, they won’t rot or attract pests if left in a damp corner of the barn. This is the sack to use if you are selling your wool to a buyer who prioritizes cleanliness.

The tradeoff for that cleanliness is a complete lack of breathability. You must be absolutely certain your wool is bone dry before bagging it. Any residual moisture from the sheep’s lanolin or a humid day will be trapped inside, potentially ruining the entire fleece. Always let your fleeces air out for 24 hours before packing them in nylon.

Clear Polypropylene Bags for Easy Fleece Grading

Clear poly bags are the organizer’s dream on shearing day. Being able to see the fleece inside without opening the bag is a massive time-saver. You can instantly identify which bag holds the fleece from your prize ewe, which one has the black lamb’s wool, and which one is full of lower-grade belly wool.

This transparency is invaluable for anyone selling individual fleeces to handspinners. A buyer can see the crimp, color, and staple length right through the bag. It simplifies your inventory and makes for a much more professional presentation.

They aren’t as rugged as nylon or burlap, so you have to handle them with a bit more care. A sharp hoof trimming or a snag on a nail can easily rip them open. Like nylon, they also trap moisture, so ensuring the fleece is dry is non-negotiable. Think of them as excellent for sorting and selling, but less ideal for rough handling or long-haul shipping.

Sydell Burlap Wool Bags for Maximum Breathability

Not all burlap is created equal. While a generic potato sack will shed fibers everywhere, purpose-built wool bags from companies like Sydell are a different beast. They are made from a higher-grade, more tightly woven burlap designed specifically for storing wool.

These bags aim to provide the best of both worlds. You get the superior breathability that protects against mildew, but with significantly less vegetable matter contamination than a cheap, loose-weave sack. For farmers in humid climates, this can be a critical feature, as getting wool completely dry can be a challenge.

While they are a big improvement, they are not zero-contamination. A meticulous mill might still prefer nylon. However, for storing your own clip for handspinning or selling to buyers who understand the benefits of breathable storage, these specialized burlap bags are an excellent, high-quality option.

Repurposed Woven Poly Feed Sacks: A Frugal Pick

Every farm has a stack of empty grain sacks, and it’s tempting to press them into service on shearing day. For certain jobs, they work just fine. They are perfect for collecting the dirty, unusable bits of wool—the tags, belly clippings, and floor sweepings—that are headed for the compost pile.

Using them for your prime fleeces, however, is a big risk. No matter how well you clean them, there’s a chance of contaminating your wool with feed dust, grain particles, or mineral residue. This is an absolute deal-breaker for any commercial buyer and can introduce allergens or debris into wool destined for personal projects.

The verdict is simple: use them for waste wool or for temporary holding, but never pack a valuable fleece you intend to sell or process in a used feed sack. The few dollars you save on a proper wool sack aren’t worth the potential loss in value of a whole year’s fleece.

Heavy-Duty Canvas Duffles for Long-Term Storage

For that one perfect, show-winning fleece you’re saving for a special project, a standard wool sack doesn’t offer enough protection. This is where a heavy-duty canvas duffle bag comes in. Think of it less as a sack and more as a fleece safe.

Canvas is extremely durable and tightly woven, offering fantastic protection against dust, sunlight, and—most importantly—wool moths. A good canvas bag with a zipper closure is a far better long-term storage solution than a plastic tote, which can trap condensation and make wool brittle over time.

This isn’t a practical solution for your entire clip, as canvas bags are expensive and not particularly breathable. But for storing one or two prized fleeces for a year or more, a dedicated canvas duffle ensures that when you’re finally ready to use that special fiber, it’s in the same pristine condition as the day it was shorn.

Paper-Lined Burlap Packs for Bulk Clip Handling

If you’re starting to scale up your flock, you might encounter paper-lined burlap packs. These are the professional’s choice for shipping large quantities of wool. They combine the rigid structure and strength of burlap with a protective inner paper lining.

The paper liner acts as a barrier, preventing the burlap fibers from contaminating the wool. This solves the main issue with traditional jute sacks. At the same time, the paper and burlap combination offers better moisture-wicking properties than a pure plastic sack, providing a buffer against condensation during long transit.

For a hobby farmer with five sheep, these are overkill. But if you’re part of a local wool pool or are shipping a dozen fleeces to a distant mill, these packs offer a level of protection and professionalism that ensures your clip arrives in top condition. They represent a smart compromise between the breathability of burlap and the cleanliness of synthetics.

Using a Wool Press for Tightly Packed Sacks

A wool press isn’t a type of sack, but a tool that dictates the kind of sack you must use. This simple manual device allows you to compact a huge, fluffy pile of wool into a dense, square bale. For anyone with more than a handful of sheep, it’s a revolutionary tool for saving storage space.

When you use a press, you put an immense amount of strain on the wool sack. A flimsy, clear poly bag or an old feed sack will split at the seams instantly. You absolutely must use a sack designed to handle the pressure.

This means choosing either a heavy-duty nylon sack or a top-quality, tightly woven burlap pack. The force of the compacted wool will exploit any weakness, so this is not the place to cut corners. Investing in a wool press makes sense when your shearing day pile starts to take over the whole barn, but it requires you to pair it with sacks that are up to the task.

Ultimately, the right wool sack isn’t about finding one perfect bag, but about building a system. Use clear bags for sorting, burlap for breathable transport, and repurposed sacks for the rough stuff. Matching the sack to the fleece’s final destination ensures you get the most value from your flock’s hard work.
