One of the more rare packs I’ve found hailing from just up the road, Fort Collins, Co. This early 90s DeFrance pack is technical for its time, but based on sound pack design. The plastic wing hip flairs remind me of an early Gerry model with a removable rigid foil (I think there’s a post buried somewhere in the archive).
Great use of vibrant colors indicative of the early 1990s. Yellow compression straps almost encompass the main body
for a secure gear fit. I can imagine the popularity with those looking for lightweight loads and secure, fast paced travel up trails and extreme terrains, perhaps even climbing or skiing. The top becomes a waist pack for satellite journeys. The top detaches to become its own oversized waist pack. I’m unsure if this pack may have had a removable rigid spine, as found there was none.
Second to last pic is from the April 91 Backpacker Buyer’s Guide issue detailing DeFrance offerings. I believe this is the Trixter model.
The last pic is from a waist pack I found of the same name, but hailing from Sedona, Az. The Sedona examples I’ve come across utilize more muted fabric colors and appear to be overall less technical. Not sure the relationship, but I believe it to be a pre or prior iteration by the same maker.

Hi Rob, these packs were made by a gentleman name del be France in San Marcos California. Dale, my mother, & mysef made these backpacks in 1989–90. Dale was a very creative guy and always came up with better ideas for packs. I still have one of his backpacks that he custom made for me in high school to this day, I am 52 years old. I lost contact with him decades ago, and would still love to find him to this day..
Toby, thank you so much for commenting. Great to get some first-hand history on these packs! I truly enjoy the innovation and inginuity in these packs. I sent this particular one to a friend in Japan, but have since found a blue version which I am keeping.
