How To Make A Trash Pack

What A Trash Pack Actually Is

A trash pack is a compact, wearable bundle of heavy-duty trash bags stored in a small container, designed for outdoor activities where you need a quick solution for waste management, gear protection, or improvised waterproofing. It's the kind of thing hikers carry on long trails, campers toss in their gear box, or anyone who travels and doesn't trust roadside rest stops. You buy a small zippered pouch or a simple plastic case, stuff it full of folded 33-gallon contractor bags, and clip it to your pack. That's the whole concept. The value isn't in the container. It's in having five or six properly sealed bags in something smaller than your hand whenever you need them. I've carried one on every long trail I've done since around 2009. The first time I actually needed mine, I was in the Sierras during an unexpected afternoon downpour and had to waterproof a spare set of clothes before I could stop for dinner. A standard black kitchen bag from a gas station doesn't fold down small enough to justify the effort. A dedicated trash pack sits in your pocket and works when it matters.

How To Make A Trash Pack

You don't actually need to build anything complicated. Here's the straightforward version. Gather the following: contractor-grade trash bags, a small zippered pouch or hard-sided case, and optionally a carabiner or elastic band. Contractor bags are the standard choice because they're thicker than residential bags, usually 3 mil or more, and come in rolls that flatten out efficiently. The 33-gallon size is the most versatile. Anything smaller becomes fiddly when you're stuffing it into a pack with cold fingers. Anything larger is bulkier and harder to fold compactly. The container is the only variable that matters beyond the bags themselves. A zippered pencil case works fine. A small tackle box works better if you want protection from crushing. A dedicated dry bag insert is overkill but effective. I use a $4 waterproof pouch from a camping store and fill it with folded contractor bags. It fits in my jacket pocket without any bulk.

Assembly Steps

First, take the contractor bags out of their original packaging. Most come rolled or tightly folded in a way that defeats the purpose of compact storage. Stack them flat, then fold each bag in half width-wise, then in half again length-wise, then roll or fold them into a compact rectangle. The goal is uniform thickness so the bags nest together tightly without gaps. A neat stack of folded bags takes up roughly the same space as a smartphone and weighs about as much as a handful of coins. Load the folded bags into your chosen container. Aim for five to eight bags depending on the size of the container. More than that and the container gets too full and the bags can burst through the zipper or lid under pressure. Less than four and you're not really carrying a trash pack, you're just carrying one bag in a case. If your container has a built-in carry strap or loop, attach a carabiner. If not, loop an elastic band around the outside or sew a small webbing loop onto the side. You want something that clips onto a daisy chain, hip belt, or pack exterior without sliding around.

Where To Put It When You're Moving

Clip it to the outside of your pack near the top so you can grab it without unstrapping anything. If you're hiking in snow or heavy brush, move it inside a side pocket. Getting snagged on a branch and losing a trash pack mid-trail is a real problem, and I learned that the hard way on a section of the Pacific Crest Trail near Lake Almanor. A jostling pack, a loose carabiner, a branch sweep. One moment it was clipped to my hip belt, the next it was caught on a deadfall branch and I didn't notice until I'd gone another mile. I had no bags, a half-full water bottle leaking in my pack, and rain coming. I ended up using a spare bandana to wrap the bottle and kept going. After that, I switched to a sewn-on webbing loop instead of a carabiner. The loop tucks flush against the pack and won't catch on anything. Most beginners buy expensive specialty bags and forget the core principle: trash packs exist for utility, not presentation. A $30 branded waste kit sounds impressive until you realize it holds three thin bags and costs more than a roll of contractor bags from Home Depot. The math doesn't work. A single roll of 33-gallon contractor bags runs about $6 to $9 and gives you anywhere from 20 to 40 bags depending on the brand. That's roughly ten times the capacity of most commercial kits at a fraction of the price. The other common mistake is folding technique. Randomly stuffed bags create an uneven pile that expands outward and makes the container bulge. Uniform folds keep everything tight and predictable. Take thirty seconds to fold them properly and your pack sits flush against your hip instead of bouncing around like a loose brick.

There are trade-offs you should know about. Contractor bags tear if you overstuff them or drag them across sharp rock. They degrade under prolonged UV exposure, so if you're leaving a pack in direct sun for days at a time, the bags will become brittle and crack. I've seen this happen on multi-day desert crossings where a forgotten pack sat on a dashboard in 110-degree heat for four days straight. The bags were dust by the time I unpacked them. Rotate your stock every six months if you store packs in hot environments, and keep a separate stash for desert use with UV-resistant bags like Hefty Ultra Strong or equivalent. If you need something more durable than trash bags, consider a dedicated trash compactor bag system. These use thicker, interlocking bags designed for repeated compression. They cost more upfront but last longer and hold shape better under heavy loads. I don't use them for casual hiking because the added weight and bulk aren't justified for short trips. They're worth it on sustained backcountry routes where you're managing food waste and general trash for five or more days. Another scenario where a basic trash pack falls short is cold-weather use. At sub-freezing temperatures, regular contractor bags lose flexibility almost immediately. I carry a separate small pack of silicone-coated bags in my winter kit. They stay pliable in conditions where standard plastic turns into glass. The silicone bags are slightly bulkier and heavier, but the difference is negligible compared to having unusable bags when you need them most.

The bottom line is practical: make it simple, fill it well, secure it properly, and rotate your stock before the bags go bad. That's the entire process.
