100g sample pouch (which could be equated to roughly one meal - 3 level scoops 114g as you mentioned) is available at £4 per pouch (free postage within UK) so could perhaps appeal to those planning a trip away for a few days??
Personally I’d sooner decant my requirements into cheap tupperware, click-lock or even zip-lock packaging if I were to travel, as buying in the small pouch format, for me, would be prohibitively expensive.
I recently used zip-lock bags for a trip away to Glasgow with bottled water with a couple of shakers. Worked for me and I decided the volume (grams) which can vary dependent upon my needs.
Recycling the pouches is a non-starter too unfortunately Can we get recyclable packaging?
I’m not against variety and it has been alluded to in the past that a new [edit: Huel] product type will be announced. Just waiting to see what that might be and if it appeals.
Ambronite looks nice but perhaps that’s why it’s way more expensive??
Personally I’m very happy with Huel powder as is.
