Built for the 2026 ULTRA Travel System, this limited edition CAS1 pairs our streamlined sling platform with ULTRA 200X, creating a lighter-weight sling with exceptional durability, a waterproof shell textile, and a bright white interior for enhanced gear visibility. Designed for the moments after you've arrived, it's the most performance-forward version of CAS1 we've ever produced.
Dual sliders open in either direction. A triglide and quick-adjustment buckle create a secure sling fit, while an integrated strap keeper controls excess webbing. The U-shaped main zipper opens wide for visibility and access, and the harness angle supports comfortable shoulder-sling or waist-pack carry. A loop logo patch allows customization with EVERGOODS Hi-Vis Patches.

Originally developed for high-performance outdoor equipment, ULTRA 200X combines exceptional durability with low weight. Its waterproof laminated construction and UHMWPE fibers create a crisp, technical shell built for demanding travel.
A custom 210D Nylon 6,6 lining in bright white makes locating your gear quicker, whether you're digging through an overhead bin or packing before an early flight. The lighter-weight textile also contributes to overall weight savings without compromising durability.
All exterior zippers use YKK’s most durable RC zipper with a PU lamination that helps shed rain, snow, and splashes while maintaining smooth operation. Combined with the waterproof ULTRA shell textile, they add another layer of weather resistance for travel in unpredictable conditions.
CAS1's main compartment is divided into three dedicated organization zones:
Our back panel is custom-developed and built from a two-layer construction of 3D spacer mesh and abrasion-resistant 194 denier TPU monofilament woven. The back panel is breathable, durable, and doesn't pill.
The zippered security pocket helps divide and organize items within the main cavity and contains two drop-in slots for additional organization. One larger slot fits items like credit cards, while the smaller slot is sized for items like AirPods.
ULTRA 200X is an advanced shell textile chosen for one reason: it delivers exceptional durability while keeping weight to a minimum. Built with UHMWPE fibers and a waterproof laminate, it offers impressive abrasion resistance in a lightweight and sleek package. The fabric has a crisp, structured hand feel with a subtle cross-ply pattern that gives it a distinctly technical character.
