Review summary

CLIF BLOKS Energy Chews is a energy chew (48 g carbs/serving; no caffeine). Portionable energy chews with ~48g carbs (~200 kcal) per full packet — designed when you want to nibble carbs over time instead of taking a full gel in one go, with easy belt/vest carry. I'd shortlist it for easy to split — eat 2–3 bloks at a time on the move.

The trade-off is chewing while breathing hard is harder than gels for some — GU Energy Chews is the cleaner compare when that is most of your week. It fits buyers who actually need a energy chew (48 g carbs/serving; no caffeine), not a one-product rotation.
