Frequently Asked Questions
How do adjustable vests compare to plate-loaded or sandbag vests for rucking?
Adjustable vests typically win for rucking because removable weights spread load evenly and offer padding options. Plate-loaded vests provide compact, non-shifting weight but can feel rigid; sandbags conform but may shift and wear seams faster.
Will these RUNmax vests be comfortable for high-rep HIIT?
Yes — the RUNmax adjustable designs are made for dynamic movement and many users find them suitable for HIIT. Expect some variation by body shape and weight used; heavier loads may reveal shoulder pressure unless padded well.
What common issues should I check for after delivery?
Inspect stitching, seams around weight pockets, and straps for sturdiness. If you detect a strong chemical smell let the vest air out in a ventilated space. Test fit with a moderate load before committing to long rucks or intense HIIT.
