Review

I took the Loksak OPsak for a proper spin this year on the PCT. It’s highly recommended and popular among thru-hikers so why these odour-proof sacks?

 

Why Loksak OPsak?

Keeping food safe on the trail is important, but keeping it out of smell’s reach from critters is a challenge.  The Loksak OPsak is supposed to reduce or completely stop the odours escaping the sack while also keeping the contents dry. Before the Sierra on the Pacific Crest Trail, it’s okay to use one of these to store your food in but further than Kennedy Meadows and you’ll be required to use a bear canister to store your food. While in thee Southern California desert I kept all my food in this OPsak at camp and didn’t have a single problem with rodents trying to break into my tent and have a nibble. That said, it was early in the season and temperatures were colder than usual.

 

Is it actually odour proof?

While it’s certainly odour proof when new and probably still after being used, a residue of food you’ve been handling can become smudged all over the outside of the sack so it’s important to give the OPsak a wipe down with an odourless wet wipe or with a bit of water using your Buff to clean it off before hitting the hay.

 

What’s there not to like?

Someone in REI said that the OPsaks with the green enclosure were meant to be more effective at keeping food inside, how true that is I’m not sure, let me know in a comment below if you know if that’s correct. With that, it’s impossible to find the green ones available this side of the pond.

 

Value for money

For a pack of however many you order, £20 is a good price, but the likelihood of needing the full set on a thru-hike is slim. I ended up purchasing a multi-pack and only needing one and mailing them off to a friend in WA.
