These are my go to bags for backpacking. I use the 20L for food. It easily hold 10 plus meals for myself. Durable, lightweight and waterproof. I use the smaller sizes for organizing my bag(s). I love the bright colors!

I have some heavy duty dry bags but wanted something lighter and multipurpose. I bought an 8L to start out with and I'm able to get my 20 deg Feathered Friend Wide/Long quilt in it (barely). I've also used it and a food storage bag on other trips and it rolls up great and keeps things dry. It also is easy to clean and very lightweight without being fragile. The reinforced collar for rolling is great.

I purchased the 20 liter dry sac as bag liner for my 40 ultimate Direction Fast Pack. Given the wt and durability this is a great option for pro texting items inside the pack for 4-5 day excursions during a fast pack trip or even a 100 mile race. The peace of mind knowing your gear is safe inside like sleep system and electronics “power bank” are a game changer. I did try polycro bag liner a bit to fragile for me. Over all happy with the purchase and would buy again and recommend for UL packing.

These bags are extremely light weight, durable, and fully functional. Used two of the 13L on recent 12 day backpacking trip in the Rockies. We only had rain for a total of about 20 hours. (typical afternoon storms). I used one for my two man backpacking tent strapped to the outside of my Atmos 65 backpack, and the other for my spare clothes inside the pack. Neither got wet while inside these bags!! I love how the bag sides cling together as you compress it down making for a tight water proof seal as you roll it down and buckle together. New replaceable buckles will make it easy to repair if one breaks--not an issue on this trip. Great super light weight bags. Will get more of different sizes and colors. Great selection!
Just The bags I needed. I warm planning on using the 35L bags for my zero degree down quilts as emergency bag in my truck along with gloves matches beanie, ect.I bought some smaller bags with emergency gear in mind.I will setup with At least 2 bags for emergencies,. I figure a larger bag is easier to find In an emergency and the orange bags I have purchased are for the reasons and they are waterproof. Thanks Sea to Summit
Super light weight, Durability looks like it will hold up over time. I like the new style repair buckles. I ordered orange in case I decided to hike during hunting season here in the NE. I have quite a bit of sea to summit gear and some of it is 10+ years old. I have not been disappointed yet.
These dry sacks are perfect for backpacking! I keep my clothes in one, my sleeping bag in another and my food in a 3rd. This eliminates the need for the annoying pack cover. And when push comes to shove, I can toss my electronics ie phone, battery pack, headphones etc into the food bag if it rains. I own several in various sizes and they’ve always been clutch.
Needed a light weight 35L dry sack as a pack liner. The ultra-sil dry sack fit just right in my Blaze 60 pack. All my gear fits with extra room. The dry sacks arrived quickly and in great condition. Highly recommend them.
These sacks are the best! I only use Sea to Summit stuff sacks and dry sacks. I've not found another brand of sacks that are any where close to as reliable and well made. The Ultra-Sil dry sacks are fantastic for backpacking. I use them for storing electronics, storing my tent, storing clothes, storing and hanging food, basically for everything. If you're looking for an ultralight, durable, and reliable dry sack, you cannot go wrong with these sacks!
