I've been carrying the Zenlet minimalist wallet for about a year now, but I have more cards (ID cards, work cards, etc.) than I can fit in this bag. I recently bought one of these HUSKK overflow units. I didn't have a traditional wallet in my back pocket for 30 years, but I carried everything I needed in my shirt pocket. Because I always wear a shirt with a collar and two breast pockets. Usually it is a ventilated fisherman shirt. In any case. I loaded my overflow maps into a HUSKK setup and used them for about a week. Oh, I also keep cash in it because zenlet is not suitable for that. I'm almost certain I could just take the HUSKK with me instead because it's roomier and - with diagonal outer slots - keeps my most-used cards close at hand. This is a very well built wallet. The skin is comfortable, the seams are tight, it looks great. I'm glad I pulled the trigger and got it. Throw out all that crap you carry around in your wallet every day, downsize it to what you actually use and buy one of these. You'll thank me and your ass.
