Great Compression Sack

Great compression sack, I love the strap on the bottom to help pull items out and that two of the straps have buckles making it much easier to open and re-attach - small be very nice touch. Of course the strength of the material is spot on.

Wouldn’t Go Out Without Them

I bike pack in Norway on extended bike packing trips. It is wet. It’s important to stay dry and organize. I use these bags for everything.

A Must-have For Travel – Excellent Compression And Quality

I bought two of these compression sacks—one for myself and one for my wife—for a two-week trip to Iceland, and they were absolute game-changers. The quality is excellent, and they held up perfectly throughout the trip. We were able to fit all our clothes with ease, saving a ton of space in our luggage. These sacks made packing much more manageable and efficient. I’d absolutely recommend them to anyone traveling, and I’ll likely be buying more for future trips.

Great Purchase

Really happy with my 20 Liter compression sack. I use it for travel packing. It compressed my clothes with minimal effort and minimal wrinkled garments. Very easy to use and sturdy. I definitely recommend this and my brother-in-law bought two based on my suggestion! See my 'before' and 'after' pictures!!

I love this compression sack it has lasted me a while and I have used this same still for upwards of 2 years and I love it, it is the best combination of lightweight without sacrificing durability along the way.

Ultra-sil Compression Pack

I purchased one of each of these packs for my daughter and son in law for Christmas because they are frequent travelers who like to contain their luggage to carry ons and a backpack each, especially when traveling internationally. They also go skiing a couple times a year and on that trip they have to pack very bulky jackets, ski pants, sweaters and lots of layers of clothes. They have not traveled with them yet, but they did do an experiment with stuffing one of them and they were amazed at what they were able to pack and how small they were to shrink the sack down to! They can't wait to use them next month for a ski trip. I have now decided to buy one for myself.

Another Great Sea To Summit Purchase

Like so many Sea to Summit products this one delivers on all expectations. Light, water resistant (bordering on waterproof) and well made. Keep up the great work STS!!!

Really Well Done!

I got these for a beach vacay, with the hopes of compressing all my clothes, swim suits, etc to avoid a checked bag. I haven't gone on the trip yet, but I did test how many clothes it could stuff using clothes I had piled up in my hamper. I was very impressed, it could definitely hold more than a weeks outfits. the straps felt very durable. I was using my whole body weight and pulling as tight as I could, and the straps still felt like they weren't gonna budge. I'm very excited to be taking these on my trip, I'm looking forward to not having a huge mess of clothes and being able to comfortably pack other things in my carry on. Looking forward to using these on future trips!

Necessity For Packing

Literally reduces the size of what I am packing to less than half. Will never go on a trip without this.
