Petzl's ultra-light Dyneema sling offers the most compact sling that we tested while still maintaining full 22kn strength. With an 8mm width these slings are 4mm thinner than Petzl's already compact StAnneau Dyneema slings.
FinAnneau slings are super lightweight and compact; a full 2mm thinner than the Black Diamond Dynex Runner. Unfortunately what you save in weight and bulk you might sacrifice in durability and therefore, product life. If you absolutely must have the lightest and most compact sling on the market, these are the slings for you, but due to their high cost and low durability you might be more satisfied with a slightly larger, longer lasting product such as Trangos Ultratape. For a skinny, durable sling option, we recommend the Mammut Crocodile Sling.
