Product Description Item No.   10270416

The Osprey Straight Jacket Compression Sack is a storage sack for backpacking. The Straight Jacket comes in four different sizes, all with a rectangular shape for packing into your backpack with efficiency. The large zipper opens wide to stuff and jam sleeping bag, extra layers, and more inside, then use the dual straps (three straps on the 32L) to cinch it down smaller than what you started with. The water-resistant fabric is a 40D nylon ripstop to protect the items you have on the inside. The Straight Jacket and it's seams have been waterproof coated, but not the zippers so I definitely don't recommend throwing this into a river. Your stuff will get so wet.

FEATURES of the Osprey Straight Jacket Compression Sack

  • Compressible nylon wings and buckles
  • Compression sack rectangular shape
  • Water resistant with waterproof coated fabric and seams (zippers not waterproof)

OSPREY MEASUREMENT GUIDE

Please note that the info provided above refers to the torso size each pack will fit, and NOT any dimensions of the pack. Below are some steps for how to get your torso length. You should probably have someone help take this measurement for you so it is accurate. And they might accidentally touch your butt.

HOW TO MEASURE TORSO LENGTH:
• Start at the iliac crest, which is the top of the hipbones on the side of your body. These act like a shelf for supporting a pack hipbelt.
• From this level on your spine, measure to the C7 vertebrae, the knobby bone at the base of your neck when you put your head down.
• Make sure you keep your back as straight as possible while measuring.
• This torso measurement determines what size Osprey pack you should carry. Refer to the size charts above to find your ideal size.
• If you are in between sizes, it is ideal to try them both on before ordering.

HOW TO MEASURE HIPBELT SIZE:
• Measure around your hips at your iliac crest, NOT your waist.
• A properly fitted hipbelt rides centered over the hipbones and needs to be very snug.
• The padded portion should wrap well around your hips, leaving a gap of 3 to 6 inches between the tips of the both hip pads when securely tightened.
• Refer to the Hipbelts size chart above to help determine your ideal Osprey pack size, but again, your torso length is what should determine your pack size, NOT the hipbelt.

Rated 3 out of 5 by from Not as effective as I hoped I bought this for my 10 year old son on the grounds that it's a lot easier to get a sleeping into this bag's bigger opening and he'll be going on a lot of boy scout camping trips. But the problem is when you get it cinched down, the bag bulges in inconvenient ways that make it had to get it into the backpack. The whole point was to make it as compact as possible. furthermore, we just got back from a 3 day family trip and one of the seams is already coming apart. On the other hand, I got a smaller one for my own down sleeping bag, and it's working better. it is easier than the traditional model. But I'm still going to return my son's and get him a traditional compression sack that can go on the outside of his pack.

Rated 5 out of 5 by from Excellent Sleeping Bag Compression Sack I used this to replace my SnugPak Jungle Bag original compression stuff sack. I normally had to roll the bag perfectly tight to make it easily fit into the original sack, and that is too time consuming. The side opening feature of the StraightJacket is perfect, as well as the 8L size, and compression. Well done. I'm rethinking of other sacks to replace with other StraightJackets.

Rated 5 out of 5 by from Compression - how I love you! Bought a few weeks ago and took on a trip to Colorado - main intent was to get all skiing cloth in a more manageable format/volume. The compression sack is doing an outstanding job with that, did fit four sets of skiing pants, hard shells as well as gloves and pullovers in - pressed in. After compression applied, I would estimate the pack size to be half of initial pack volume.

Rated 5 out of 5 by from Perfect shape and high build quality If you get the right size were you don't have to over stuff it it is very easy to load and compresses Nicely into a longer thin tube shape which works so much better in my pack than the ball/ pancake shape of standard sacks. Excellent design and build quality in a light weight package
