What you need, nothing more
These draws are the cheapest you're going to find anywhere. Nylon is heavier than Dyneema, and full-size carabiners are heavier than small ones. If you're looking to shave grams, these aren't your draws. But if you're looking for a draw that's easy to clip, has a dogbone that won't twist, and costs less than anything else out there, you've found it.
The way I look at it, you could spend more money on lighter draws -- but why not just get stronger carrying these?
