Rennen X-Pac Laptop Daypack 22L

Boundary Supply Rennen X-Pac Daypack — The Rain-Ready Carry-On for Minimalist Digital Nomads

The gist: A 22L, USA-made X-Pac daypack that fits 99% of airline carry-on bins without sacrificing your 15” laptop’s safety.

• Waterproof exterior: Custom VX21 X-Pac fabric repels rain and resists tears — no separate rain cover needed on travel days.
• Carry-on compliant: 46 × 28 × 18 cm profile fits 198 out of 199 airlines, so you never pay to check a bag.
• Nywool laptop sleeve: 15” padded Nywool compartment with YKK Stormguard zippers keeps your laptop cushioned and dry.
• Packable weight: 2 lbs (0.9 kg) leaves your carry-on weight allowance for gear, not the bag itself.

According to onebag.travel’s carry-on compliance database, the Rennen X-Pac achieves a 99% airline fit rate — among the highest in its category.

Best for: Minimalist travelers and digital nomads who need a single weatherproof bag for a 15” laptop and a week’s essentials. Skip it if: You carry heavy camera gear or need more than 22L — the single main compartment fills up fast, and there’s no sternum strap for loaded carries.
