Ultralight 350 Reviewed In Adventure Travel Magazine

Adventure Travel Magazine’s 3 Season Sleeping Bag review saw the Criterion Ultralight 350 achieving a score of 8 out of 10.

This independent review, in one of the leading outdoor sector magazines, once again shows Criterion to be one of the best manufacturers of down sleeping bags. When our racing/ultralight backpacking sleeping bags do so well in general sleeping bag tests it is an affirmation of our policy to use the best materials we can, whilst trying to keep the weight down as much as possible.

Adventure Travel Ultralight 350 Review in Full

“The Criterion Ultralight 350 is handsdown the most packable sleeping bag in this test, taking up as much room as a small loaf of bread might. This is fantastic for those looking to reduce the size and weight of their packs (it’s the lightest sleeping bag too, at just 800g), but for this, you do sacrifice a few features. Admittedly, this is something that the folks at Criterion were prepared to sacrifice to attain the weight and packability of the bag.

The big omission is the lack of neck baffle, so you’ll need to cinch in the sleeping bag’s hood for it to work effectively in colder climes. Doing so is an easy job with one hand, and once cinched, it retains heat well.

The sleeping bag uses 700 fill power white goose down, and it lofts very well. A comfort rating of -3C means you will be covered for much of spring, summer and autumn, but other bags here are warmer. It’s also worth noting that the Ultralight 350 does not use water-repellent down, so it’s not as well suited to damp environments. However, it is very well suited to lightweight travellers and backpackers looking to get a good sleeping bag for an affordable price.”
