Streamline

Streamline is a Shopify theme from Archetype Themes, and its core demo plays an activewear label called Force. You land on a full-screen video of two runners crossing a city footbridge, a plain "Find your perfect pair" line in the corner and a white pill button under it. The palette is close to monochrome, a deep charcoal against off-white, with Red Hat Text for headings, so the athletes and the clothes bring the color.

What stands out is the navigation. Once you scroll past the hero, the regular header gives way to a big floating Menu pill pinned to the bottom left. The homepage then stacks a dark sale bar with a live countdown, a leggings carousel with color dots, a "20% off" image banner, a tops row, a shop-the-look photo with a hotspot that links to the bra being worn, an Our Story block, a dark Clearance carousel, a Perfect Fit slideshow, training articles, rounded category tiles for bras, leggings and tops, and a pale green newsletter band. The product page pairs a thumbnail column with a large photo, crossed-out sold-out sizes, a low stock note, and separate Add to Cart and Buy It Now buttons. We like the crossed-out sizes: shoppers see what's gone before they click.

On a 390px phone the video hero shrinks to a short band, the countdown sits in its own dark block below, and the Menu pill stretches almost full width along the bottom.

We'd pick Streamline for a fitness or apparel brand with good movement footage and a modest catalog. Before you launch, update the dated demo copy: the lookbook menu points at seasons from a few years back and the clearance block promises a sale ending in August.
