What Size OPSAK for Backpacking?

By Anna Duncan

When it comes to backpacking, having the right equipment is essential. One of the key pieces of equipment is an OPSAK, which is a waterproof, odor-proof bag that helps keep food and other important items dry and safe while you’re out in the wilderness. But with so many different sizes of OPSAKs available, it can be difficult to know which size is best for your particular needs.

In general, the size of OPSAK you need for backpacking will depend on what type of trip you’re taking and how much food and supplies you plan to bring along. For a short weekend trip, a small or medium-sized OPSAK should be adequate.

These smaller bags are lightweight and easy to carry around, and can accommodate enough food for up to three days. However, for longer trips or trips where you’ll be carrying more supplies, a large or extra-large OPSAK may be necessary.

When selecting an OPSAK size, it’s also important to consider how much space you have in your pack. If you have limited space in your pack and need to conserve room, an extra-small or small-sized OPSAK may be ideal. For those with larger packs that can accommodate more gear, larger sizes may be necessary in order to fit all of your supplies.

Another factor that should be taken into consideration when selecting an OPSAK size is how easily the bag will open and close when filled with items. The last thing you want on a backpacking trip is a bag that won’t stay closed or doesn’t open easily when needed. Smaller bags will usually open more easily than larger ones, but they may not have enough room for all of your supplies if you’re taking a longer trip.

Conclusion:
When choosing what size OPSAK is best for backpacking, it’s important to consider the length of your trip, how much space you have in your pack and how easily the bag will open and close when filled with items. For shorter trips or trips where space is limited in your pack, a small or medium sized OPSAK should work well; however if you’re taking a longer trip or carrying more supplies then a large or extra-large sized bag may be necessary.
