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!!

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.

Perfect For Travel

Bought to use for backup clothes in my carry on, in case my checked bag is delayed. I can fit a whole change of clothes, including jeans, without any problems.

Great Compression Sack

I ordered a yellow sack a couple of months ago for my Zen Bivvy quilt & sheet (the brand sack was backordered.) The Sea to Summit sack saved me $15, came speedy-fast and works great - compresses well and is versatile. It also has enough room to store my inflatable pillow so everything is in one place when camping. It is definitely more of a goldenrod yellow so the color doesn't match the Zen Bivvy sheet which is more of a true yellow but overall I'm very pleased with it..

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!!!
