Splashproof, lightweight compression sack helps save space & is easy to access.
Light, versatile, and small-packing, the Blocker Compression Cinch Sack pairs a fast draw cord opening with our smart compression system to ensure soft, bulky contents are easy to condense and pack efficiently in a boat or backpack, all while remaining easy to access.
Details
- Versatile materials: Lightweight 70D polyurethane-coated nylon materials are a tougher, more resilient cousin to the ultralight BlockerLite materials. More durable and versatile, these materials are great for all-around use and provide dependable splash protection.
- Smarter compression: Unlike conventional systems that pull against seams, our Continuous Compression system encircles the sack to minimize seam strain, maximizing durability for dependable protection.
- Securable, easy access: Draw cord closure supplies speedy, hassle-free access to contents while the lockable cord lock ensures the sack stays cinched tight.
- Durable construction: Fully welded seams result in stronger and more durably protective construction compared to sewn-and-taped seams.
- Efficient-Packing: PackTight™ packing system sacks feature flat-sided, rectangular shapes that nestle closely together, packing 20% more efficiently than rounded sacks for easy, space-saving organization.

MY FAVORITE SOCKS
Size: Large, Color: (001) Black / Black / Pitch Gray
I bought these originally at my local UA store and had to buy more. They are my favorite daily wear.

A sock with real support and thickness!
Size: Large, Color: (001) Black / Black / Pitch Gray
I’m pretty happy with these. It seems like sock manufacturing changed 10-15 years ago, and it’s become hard to find pairs that are actually thick and durable. I bought these for an event where I knew I’d be on my feet all day, and they did not disappoint.
They provided excellent support throughout the day, even while wearing shoes that typically make my feet ache after just a couple of hours. Glad to finally find a pair that feels well-made.
