First Impressions of Ocun 12mm Dyn ST-Sling
The Ocun 12mm Dyn ST-Sling is a piece of equipment that, on the surface, seems quite simple, but is utterly essential for climbing and mountaineering. This sling, manufactured by Ocun, is designed for creating alpine draws, extending anchor points, and a myriad of other applications where a strong, lightweight, and low-profile connection is crucial. It promises durability and minimal bulk, features any experienced climber will immediately appreciate.
My interest in the Ocun 12mm Dyn ST-Sling stemmed from a need to lighten my alpine climbing rack without sacrificing strength or safety. Standard nylon slings, while reliable, can be bulky and absorb a significant amount of water, adding weight and potentially freezing in cold conditions. I was looking for a Dyneema sling that offered a smaller profile and reduced weight compared to my existing nylon options.
Upon receiving the Ocun 12mm Dyn ST-Sling, I was immediately impressed by its sleek design and feather-light weight. The Dyneema webbing felt incredibly strong yet supple, inspiring confidence right out of the package. The low-profile 12mm width seemed ideal for reducing bulk on my harness and in my protection placements.
Compared to my older, wider nylon slings, the Ocun 12mm Dyn ST-Sling felt significantly more streamlined. I also considered purchasing similar Dyneema slings from Black Diamond and Petzl, but the Ocun sling’s competitive price point and positive online reviews swayed my decision. My first impression was one of excitement and anticipation to put these slings to the test in the mountains.
Real-World Testing: Putting Ocun 12mm Dyn ST-Sling to the Test
First Use Experience
I first tested the Ocun 12mm Dyn ST-Sling on a multi-pitch trad climb in the Shawangunks (the Gunks) of New York. The climb involved a mix of crack climbing and face climbing, requiring frequent gear placements and anchor building. The sling performed admirably in these diverse situations.
The Ocun 12mm Dyn ST-Sling proved easy to manipulate with gloves, even in slightly damp conditions thanks to a light rain shower that passed through. Its thin profile made it ideal for threading through tight placements and extending protection without excessive drag. I experienced no issues whatsoever during the first use; the slings performed flawlessly and boosted my confidence.
Extended Use & Reliability
After several months of regular use in various climbing environments, the Ocun 12mm Dyn ST-Sling has held up remarkably well. I’ve used them on granite, sandstone, and even some icy alpine routes. The slings show minimal signs of wear and tear.
Despite being subjected to abrasion against rock and exposure to sun and moisture, the Dyneema webbing has retained its strength and suppleness. Maintaining the Ocun 12mm Dyn ST-Sling is relatively straightforward; I simply wash them with mild soap and water after particularly dirty climbing sessions. Compared to my experiences with nylon slings that tend to stiffen and fray over time, the Ocun slings have proven to be significantly more durable and reliable.
