the leather on the tri-strap is a thicker, soft leather. I wouldn't describe it as "smooshy" altho some people might. It's not squishy like say, a Gustto or a Bulga. It's a little glossier, with a little bit of a shine to it. It's not a raw leather. I would describe it as a little bit thicker Baleniciaga - a little vein-y, with natural folds & wrinkles. A little delicate, maybe. It is also thick enough to hold its shape & won't collapse when you set it down, or if it's not completely full.
The bag is well made, and like a Balenciaga, can a hold a lot w/o looking over-stuffed. The front pocket is easily accessible & is perfect for your cell phone or other things you might readily need.
I think the tri-strap is the perfect alternative for people who may not be able to afford or have the opportunity to own a Balenciaga. The bag comes in lots of colors, and has a similar shape & look to it when carried on the arm. I really like mine (I have it in Smoke Blue) a lot.
