2026 SpeedCup - 50 Cup Pack

These things have survived being shoved in my pack, stepped on, and tossed in the aid station bucket dozens of times, and the RF welded seams still show zero wear. They pack down so flat that I forget they're even in my race vest.

Rolled one of these up in my vest pocket and forgot it was there until the aid station. The RF welded seams held up fine even after I stuffed it in with my keys, and it collapses down smaller than my fist. No leaks so far after a dozen washes.

Took one of these on a 50k last weekend and it barely registered in my vest, which is exactly what I wanted. The TPU feels tough enough to survive getting shoved in and out of pockets all day, and the welded seams haven't leaked a drop.
