Arc'teryx Alpha LT, made in Canada. It's an older item, but I've taken good care of it, so it's in good condition. - Brand: ARC'TERYX - Size: S - Color: Black Features Athletic with e3D. The biggest difference from the SV, more than just the features, is the fabric used. The SV is designed to handle more severe conditions, so it uses durable N80p, while the LT prioritizes lightness, using the thinner N40p-X Gore-tex-pro in comparison. The LT is over 100g lighter because some features have been removed compared to the SV. Also, it's much easier to wear as everyday wear compared to the SV, without being stiff. As an item from the ASCENT category, designed for climbing and alpine climbing, it offers exceptional freedom of movement among Arc'teryx wear. Looking at the three-dimensional cut and the fabric construction, and actually trying it on, you can understand why it's expensive; it boasts meticulous craftsmanship.
