Turn the aLOKSAK Multi Pack into a trail-ready waterproof system. Four sizes, four jobs, and the mistakes that soak your phone or flood your food bag.
Quick answer
Use the aLOKSAK Multi Pack as a four-part waterproof system: the 4" x 7" pouch for a phone or wallet, the 6" x 6" for small electronics, the 9" x 6" for first-aid or repair items, and the 12" x 12" for larger gear or food. Seal each one with a full-width fold, squeeze out trapped air, and check the closure before every wet crossing. The set is certified waterproof to 200 feet and made in the USA from reusable medical-grade materials.
Why aLOKSAK pouches beat one big dry bag
A single roll-top dry bag forces you to open everything to reach one item. The aLOKSAK Multi Pack splits your kit into four independent waterproof pouches, so a wet hand touching the phone pouch never risks your sleeping bag or food. The 4" x 7", 6" x 6", 9" x 6", and 12" x 12" sizes map cleanly to phone, electronics, small essentials, and bulk items. Because each pouch is reusable and recyclable, you can rebuild the system trip after trip instead of buying disposable bags.
How to assign the four pouches before you pack
Assign by water exposure, not by category. The pouch most likely to be opened in rain or at a river crossing should hold your phone and ID. The next most exposed pouch holds headlamp, battery bank, and charging cable. Keep a third for repair and first-aid items that must stay dry to work, and the largest for food or a spare layer. Label each pouch with a permanent marker so you can grab it without opening all four.
Sealing and packing without trapping air
The most common failure is a partial seal. Press the closure across its full width, then run your thumb along the fold again. Before you close it, flatten the pouch and push out excess air; trapped air expands at altitude and can stress the seal. Pack the pouches vertically against your back or along the side of your pack so they do not sit under a hard water bottle or stove. A pouch pressed against a sharp edge all day is more likely to wear than one that rides flat.
What the aLOKSAK waterproof rating actually covers
The Medium Multi Pack is certified waterproof to 200 feet / 60 meters and gives 100% protection from water, sand, humidity, and snow. That rating assumes the seal is clean and fully closed. Sand or grit in the closure is the main real-world leak path, so wipe the seal with a damp cloth after a dusty section. The pouches are FDA and NSA approved for food and biohazard storage, which means you can use one for food without worrying about the material. If you need a shelter that handles the same weather, the Lunar Duo Backpacking Tent is a two-person single-wall option at 45 oz. and the Lunar Orbiter Tent is a freestanding solo shelter, but neither replaces the need for sealed electronics storage inside your pack.
Step-by-step: build your aLOKSAK system
- Match pouch to item: Put your phone in the 4" x 7" pouch, headlamp and battery bank in the 6" x 6", first-aid and repair kit in the 9" x 6", and food or a spare layer in the 12" x 12". Checkpoint: if an item rattles around, move down a size so the pouch stays flat in your pack.
- Clean and close the seal: Wipe the closure with a damp cloth, press the full width of the seal, then run your thumb along the fold a second time. Common mistake: sealing over sand or grit, which creates a slow leak you will not notice until your phone is wet.
- Purge air and flatten: Before the final press, push trapped air out of the pouch and flatten it so it packs without bulging. Checkpoint: at altitude, a puffy pouch means trapped air, so reopen and purge again.
- Pack for protection: Slide pouches vertically against your back or along a soft side of your pack, away from stove, bottles, and sharp edges. Common mistake: letting a pouch sit under a hard water bottle, which abrades the film over a long day.
- Test before the trail: At home, seal a tissue inside each pouch and submerge it in a sink for a minute, then check for moisture. Next step: mark any pouch that fails and replace it before your trip rather than trusting it on a river crossing.
