7.7mm Ice Floss 70m 2xDry
We designed the 7.7 mm Ice Floss twin exclusively for extreme alpine and ice climbing. This design is the ultimate in lightweight, compact ropes. Its smooth, single pick sheath reduces rope drag. Ice Floss is the choice of world renowned climbers because of the usual BlueWater performance and quality characteristics. Completely redesigned with a 40 carrier braid sheath.

I still run into climbers that are skeptical of twin ropes. They are used to 9+mm single ropes and anything to do with skinnier ropes or multiple ropes just doesn’t feel right to them. Time after time when I climb with someone that hasn’t ever used twin or half ropes they walk away and the end of the day (or night) and say they are going to get a set. Bluewater makes some of our favorite ropes and the Ice Floss 7.7 twins are no different. It’s evident from the first time you pick up an end to tie in that Bluewater is a company of quality. They do not take your safety, or fun, lightly. The weave on the sheath is clean and tight, but not so tight that the handling of the rope is stiff. Clips are done with easy and falls are handled without kinking the rope. The dry treatment did an excellent job of shedding all the moisture we encountered in early season climbing. Taking the the Ice Floss twin ropes on alpine routes was a great way to split the rope load as well as extend rappels to double length, making descents faster and safer.
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.
