2 PK Water Resistant USMC MACS Sack Dry Bag (9L/20# Capacity)

Cannot understate the added benefit the valve provides on these bags, in terms of how much easier they are to pack and get to reasonable pack size. Have yet to completely soak them, but the same can be said of most drybags I've owned and I have learned to trust them nonetheless. Especially given SealLines reputation for quality.

Was a great product. As described. Placed clothes in it and put in tub for 30 min with weight to keep it under to try. All clothes dry. 5 stars.

Brand new still in the bag. Awesome for keeping dry things dry. Mil issue is what it is. Heavy and sturdy.

Great product use them all the time. Loved using them in the marine corps. Always kept my gear dry and compressed in Afghanistan

MAC sacks are great WP bags for small items like underwear and socks, and with a bit of clever folding you can even fit a poncho liner inside. They compress well, and keep everything inside bone dry. They're tough.But they're not worth 30 bucks apiece. I bought a two-pack of these from the same seller 4 years ago, and they were 12 dollars per. Buy a new dry bag from Sealine for half the price and twice the storage capacity.

A dry pack is a happy pack. These bags are great for keeping my clothes, sleeping gear, etc. nice and dry. Dry socks, the Infantry's friend.

these are smaller than I thought, but work well!

Outstanding keeps everything dry. Even took them for a swim.
