This double rope, for mountain applications only, weighs just 48 g per meter. A very modest weight, coupled with high hydrophobic performance. Intended for use in the mountains, it helps secure all fairly long alpinism excursions involving an approach over moraine and glacier. It separates, so it can be carried by two people – one of the significant attractions of double ropes. What’s Hydrophobic? Here’s an expert’s view. For years, many manufacturers have claimed to make hydrophobic ropes. Well, they would… A rope that retains no water is far lighter to carry if used in wet conditions. But now, there’s a label that actually guarantees this property. A simple UIAA test can identify truly hydrophobic ropes. The rope is placed on a sloping surface, and sprinkled with water. The rope is weighed pre and post shower. The passes the test if it absorbs no more than 5% of its weight in water. Millet’s Hydrophobic ropes only absorb 2%! To achieve this excellent result, we treat all the rope’s constituent threads: both the internal ones (core) and external ones (sheath). They are then polymerized at room temperature so that the effects of the process are long-lasting.

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
