Cleanwaste GO Anywhere Kit: Best Overall Option

The Cleanwaste GO Anywhere kit stands as the gold standard for convenience and reliability in the backcountry. Each kit includes a waste bag pre-loaded with a gelling agent, a toilet paper supply, and an antimicrobial hand wipe. Because it uses a simple, intuitive design, it remains the most foolproof choice for those new to packing out waste.

The strength of this system lies in the proprietary Poo Powder, which solidifies liquid waste and neutralizes odors almost instantly. Once used, the heavy-duty bag seals securely, offering high puncture resistance that prevents accidental leaks inside a pack. This kit is ideal for day hikers and backpackers who prioritize a hassle-free, sanitary experience over minimal weight.

If you are heading into high-alpine environments or desert landscapes where waste decomposition is non-existent, this is the essential kit to carry. It eliminates the guesswork of mixing chemicals or finding a secure seal. For anyone needing a dependable, all-in-one solution that simply works, this is the definitive choice.

Restop 2 Wilderness Waste Bag: Best Odor Control

When odor management is the primary concern, the Restop 2 Wilderness waste bag leads the category. It utilizes a dual-chambered design where the waste is collected in one bag, which then slides into a second, puncture-resistant outer bag. The chemical additive within the inner bag begins breaking down the waste and odor immediately upon contact.

This system is particularly effective because of its high-quality odor-barrier plastics. Unlike standard zip-top bags, the Restop 2 seals with a robust closure that keeps biological smells from permeating your gear. It is the preferred choice for those who are sensitive to smells or for multi-day trips where waste must be stored in a confined pack space for long periods.

The trade-off for this superior odor control is a slightly bulkier profile compared to single-bag systems. However, the peace of mind offered by its multi-layered protection makes it a favorite for pack raft expeditions and long-haul trekking. If you demand a zero-scent storage solution, invest in this system.

Biffy Bag Disposable Toilet: Most Compact Choice

The Biffy Bag is engineered for the weight-conscious adventurer who still recognizes the necessity of professional-grade waste disposal. Its design features a unique, tall, fold-over bag that provides a physical shield during use, which is a significant advantage in exposed terrain. The kit includes a specialized powder to turn waste into a gel, alongside necessary sanitary cleanup supplies.

What sets the Biffy Bag apart is its incredibly low profile, making it easy to stash in a hip belt pocket or a small exterior pack sleeve. It collapses into a flat, lightweight package that takes up virtually no room. For thru-hikers or trail runners who treat weight as their primary constraint, this is the optimal balance of function and portability.

While the bag is slightly smaller than some basecamp-oriented systems, it is more than sufficient for standard use. If you want to remain compliant with Leave No Trace ethics without adding unnecessary bulk to your ultralight setup, the Biffy Bag is the logical selection.

Reliance Double Doodie: Best for Basecamp Setups

The Reliance Double Doodie system is designed for situations where a toilet chair or portable bucket is involved. These bags are built to fit perfectly inside standard portable camping toilets, providing a convenient, double-layered barrier against leaks. They are significantly larger and more robust than typical trail bags, making them the superior choice for car camping or stationary basecamp setups.

By using a double-bag construction with a zip-close seal, the Double Doodie prevents any mess when removing waste from a basecamp toilet setup. The bags are pre-treated with a waste-gelling powder, ensuring that the contents remain stable even if the bag is moved around. For family trips or extended basecamp stays where weight is not an issue, the convenience is unmatched.

Using anything else for a basecamp toilet is often a lesson in frustration. These bags are durable, simple to swap out, and offer the most sanitary way to manage waste in a group environment. If your upcoming adventure involves a stationary campsite, skip the individual kits and go straight for the Double Doodie.

LOKSAK OPSAK Barrier Bags: Top Outer Protection

Sometimes, the best strategy is not the waste bag itself, but the secondary barrier you put it inside. The LOKSAK OPSAK is a specialized, scent-proof, moisture-proof, and puncture-resistant storage bag. By placing your sealed waste bags inside an OPSAK, you effectively create a vacuum-sealed barrier that contains odors entirely.

This is a critical piece of gear for anyone concerned about attracting wildlife or simply wanting to keep the interior of their pack pristine. The material is much thicker than standard freezer bags, providing an extra layer of defense against gear snags. It is a versatile tool that can be reused across many trips, making it a cost-effective long-term investment.

Use the OPSAK as your dedicated “waste containment zone” at the bottom of your pack. While it requires an extra step, the absolute containment of scent is worth the effort in bear-heavy areas. For any multi-day trek where you are carrying multiple used bags, this outer protection is non-negotiable.

Sea to Summit Trash Dry Sack: Best Reusable Sack

The Sea to Summit Trash Dry Sack is not for direct waste collection, but rather for the secondary transport of your sealed WAG (Waste Alleviation and Gel) bags. It features a roll-top closure and a waterproof, durable fabric that keeps the contents separate from the rest of your gear. It is the perfect solution for keeping used, sealed bags organized in one place outside of your main pack compartment.

Because it is constructed with high-denier, coated nylon, it stands up to the rigors of being strapped to the exterior of a pack. It is easy to rinse out after a trip, unlike internal plastic bags that can tear or leak. This is the best way to handle long-distance backpacking where you need a dedicated, rugged transport system for your waste.

By isolating your waste in a dedicated dry sack, you simplify the pack-up process and reduce the risk of gear contamination. It is a clean, organized, and highly effective way to manage waste on long expeditions. For those who prioritize durability and repeated use, this is the industry-standard transport method.

How to Securely Pack Out Your Used Waste Bags

The integrity of your waste management system depends on how you store your bags during transit. Always double-bag your used waste, placing the primary waste bag inside a secondary sealable container like an OPSAK or a heavy-duty dry sack. Never attach a waste bag directly to the outside of your pack where it can snag, tear, or fall off without you noticing.

If you are on a long, multi-day trip, consider creating a designated “scent-proof zone” at the base of your pack. Keep this zone away from your sleeping bag and clothing to ensure that even a small leak would not ruin your essentials. Always check the seals of your waste bags before starting each day of hiking to ensure nothing has shifted or opened.

Finally, treat your waste bag as a critical piece of gear. When you reach a disposal site, inspect your secondary transport bags for any signs of wear or pinprick holes. Maintaining the physical barrier between your waste and your personal gear is the most important part of following Leave No Trace principles.

Leave No Trace Rules for Human Waste on the Trail

The core of Leave No Trace ethics is to leave the wilderness exactly as you found it. While digging a cat hole is appropriate in many locations, certain high-use or ecologically fragile areas strictly require you to pack out all human waste. This includes alpine tundra, deserts with cryptobiotic soil, and areas near pristine waterways.

Even where cat holes are permitted, you must follow specific distance rules. Stay at least 200 feet—roughly 70 adult steps—away from water sources, campsites, and established trails. Dig your hole 6 to 8 inches deep, and always cover it with natural material to blend the site back into the environment.

When packing out, never dispose of your waste bags in public pit toilets or trash cans meant for food waste. These are not designed for biohazardous material and can cause significant operational issues for land managers. Always carry your waste all the way to a proper residential or commercial disposal facility.

Knowing Exactly When WAG Bags Are Legally Required

Legal requirements for packing out human waste are becoming more common in popular, high-altitude, and desert wilderness areas. National Parks such as Denali, Mount Rainier, and many desert monuments often mandate the use of WAG bags for specific permit holders. Always consult the official park website or ranger station before heading out, as regulations can change based on the season.

Beyond legal mandates, use your best judgment in high-traffic areas. If you are hiking in a location where you see evidence of other hikers’ waste, do not add to the problem by digging a hole. In areas with thin soil or high visitation, the soil cannot break down waste effectively, making the pack-out method the only ethical choice.

Ultimately, carrying a WAG bag is a mark of a responsible, prepared backcountry traveler. It demonstrates a commitment to preserving the land for the next person and shows that you understand the limitations of the environment you are exploring. If you are ever in doubt, the safest decision is to carry it out.

Proper Disposal of Waste Bags After Your Adventure

Once you return to civilization, the responsibility of waste disposal continues until the bag reaches a proper trash receptacle. Look for standard household trash bins or designated park-approved waste disposal sites. Never dump the contents into a home toilet or a storm drain, as these systems are not equipped to handle the chemicals or solid waste contained within the bags.

If you are using a re-sealable bag or a reusable outer dry sack, take the time to clean it thoroughly once you have disposed of the internal waste. Use a mild, unscented soap and ensure the container is completely dry before storing it for your next trip. This maintenance prevents the build-up of odors and ensures the longevity of your gear.

Proper disposal is the final step in the cycle of Leave No Trace. By ensuring your waste is handled with the same care as the rest of your gear, you help protect the sanitation of our trail systems. Take pride in your ability to manage your impact, and you will ensure that the wilderness remains a clean and welcoming place for all.

Responsible waste management is a sign of true backcountry mastery, separating the casual visitor from the lifelong steward. By integrating these systems into your routine, you protect the landscape and ensure the outdoors remains pristine for everyone to enjoy. Equip yourself, pack it out, and keep exploring.
