Great piece of gear!

[This review was collected as part of a promotion.] I love this compression sack. It fits my Stone Glacier zero degree Chilkoot perfectly. It has helped with saving space in my pack. It has a nice weight to strength ratio. The quality is just of the is more than I was hoping for. This is a welcome piece of gear in my backcountry set up. Pro tip, stuff your puffy jacket and clothes into the sack and it doubles as a pillow!

• Clothes • Weight Fit

[This review was collected as part of a promotion.] The Organization is easy, the Quality and the Clothes are durable, the Size is perfect, the Weight is featherlight, and the Fit is versatile and suitable for many uses. Comes with a handle. Packable. Provides great protection. Handle for easy carry and transport. Easy to use. Fits inside larger bags. I hope for more colours and discounts available.

Great Product!

[This review was collected as part of a promotion.] Perfect for compressing clothes to maximize pack space. Lightweight and water resistant to keep out light rain and sleet on its first outing. Very satisfied.

Handy little day pack

[This review was collected as part of a promotion.] Super sturdy and a surprisingly comfortable fit. Often these small packable bags feel terrible once you put them on but not this one. I wouldn't mind if it had a chest strap or a tiny pocket somewhere but I understand leaving these things off to make it an ideal weight for adding to your backpacking gear. Very well made and a good buy!

I got this item to

[This review was collected as part of a promotion.] I got this item to stow a garment/blanket while biking or backpacking. It is the right size and based on how well the Big River dry bag is made, I trust it will serve me well. Only 4 stars because the jury is still out. Thank You.
