Choosing between a hand-tied (Feather) weft and a machine weft comes down to weight, flexibility, and how your stylist installs them. Here's a clear breakdown from the SOS Hair team.
Quick answer
Choose a hand-tied Feather Weft if you want the lightest, most seamless result and you're installing with a beaded row or sew-in. Choose a Machine Weft if you want a thicker, more durable weft that can be cut to size without unraveling.
What is a hand-tied (Feather) weft?
A hand-tied weft is made by hand-knotting individual strands into an ultra-thin, flexible seam. SOS Hair's Feather Weft weighs roughly 60–90g per weft depending on length, lies almost flat against the scalp, and stays invisible under fine hair. Because the seam is delicate, a hand-tied weft cannot be cut through the middle without unraveling.
What is a machine weft?
A machine weft is sewn on a machine, creating a stronger, thicker seam. SOS Hair's Machine Weft runs about 120–175g per weft, adds more density per row, and can be cut to any width without falling apart — making it flexible for custom sizing.

Which is better for thin hair?
The hand-tied Feather Weft. Its flat, lightweight seam hides easily under fine hair and puts less tension on the roots.
Which lasts longer?
Both are built for longevity. With proper care, either can last 8–12 months and be reinstalled through several move-up appointments. Both are 100% Remy Indian human hair, cuticle-aligned 13A.
Can I cut the wefts?
Only the Machine Weft can be cut to width. Cutting a hand-tied weft will cause it to unravel — size it by folding or laddering instead.
Both come in 15 shades. Explore the Feather Weft and the Machine Weft.
