Product Information
Lightweight
Kilogram for kilogram of working load, BB and RT Orbit Blocks are the world's lightest. The unique orbital design allows the bearing to only be in the active areas of the floating sheave. This minimizes the mass of the inactive return race and hub.
Weight and bulk are further reduced in the different block configurations. The ball bearing single and becket block has a through-sheave becket arrangement. The result? The lowest weight possible.
Multi-sheave blocks have only single intermediate cheeks and an ultra-light and efficient head arrangement. This gives a 30% weight saving advantage over the nearest competitor. Other brands just link together their single blocks. This results in unnecessary double cheeks between each sheave, held together by a heavy steel channel across the top of the block.
Highest working load in its class
The orbital ball-bearing arrangement gives the largest possible bearing race diameter. This maximizes load performance. The proven Ronstan 2-stage bearing system features high compression grade acetal ball bearings and a secondary full-contact bearing. This gives minimum friction across the full working load range.
The floating sheave and bearing system is supported by a fiber-reinforced load frame. The design was computer modeled to be stress optimized. The DyneemaA Link is produced from FSE Robline SK75 fiber, which is 10 times stronger and lighter than steel, and provides the final connection from the block to the load point.

Applications
Mainsheet systems on dinghies, sportsboats and small keelboats to 9m (30ft)
Spinnaker sheets on dinghies, sportsboats and small keel boats to 9m (30ft)
Halyard, Vang and Backstay application on boats to 8m (26ft)
Control line applications on larger yachts
Mainsheet systems and spinnaker sheets on dinghies, catamarans, sportsboats and small keel boats to 9m (30ft)
RF55410 when paired with a RF56330B and a RF35101 lashed to the becket produces a powerful 8:1 mainsheet system for use on catamarans to 5.5m
(18ft). This can be increased to 9:1 by replacing the RF35101 with a RF35202

Best wallet on the market.
Size: One Size, Color: Nubuck Black, Size: One Size, Color: Nubuck Black
This is the only wallet I buy now. Over and over. I like simple wallets. No bifold. Trifolds hurt your back. Hard case are a mess that rub your credit card mag strips off from friction. I found this a few years back and have bought 3. I am a stone worker so mine get worn from the dust and grit in my pockets faster than normal wear and I need to swap them out every couple of years. I like the simplicity and the fact that the pockets are stitched the same depth so your cards stack like varying length stair-style tabs rather than all the same depth. Wallet is RDIF protection lined. I can put like 15 cards in this wallet and it’s still thinner than a bifold holding 5. I love it. I mean it. I haven’t found a better wallet than this one. They are very well-built. Picture shows wallet with 19 cards + 40 dollars. 3/4 of an inch thick.

Good Product
Size: One Size, Color: Smooth Finish Black
Good product although the leather is a bit stiff. Hopefully it will soften up over time. Fair price, fast shipping…

So far happy.
Size: One Size, Color: Glossy Nappa Black
As everyone has made clear, it holds credit cards very tight. Almost 3 weeks in & mine seems to be breaking in a little, but cards are still a bit difficult to remove. No complaints with money clip.
One thing I thought was a dumb move on manufacturers part, was inside one of the card slots is a tag sewn into the seem. This makes things alot worse while trying to fit cards into all slots. The tag will catch on the cards & bunch up in the corner of the slot making things even tighter in that slot, plus all slots surrounding it.
I was able to get a scissors in there enough to cut most of the tag out, without cutting the stitching itself....it made a big difference....enough to fit an extra card in & without it bulging up the wallet overall.
Why would they feel it necessary to do this is beyond my pay grade. Its not like you can even see what the tag says until you cut it out.... I believe it was the name & logo....but Jesus, how unnecessary, & in the dumbest place one could possibly think of. Especially when EVERYONE comments on how excessively tight it is to fit cards in the slots & also be able to retrieve them with relative ease when needed.
Overall I am happy with this wallet so far.... I'll be interested to see if it holds together over the long haul or if the stitching gives out in a year & has to be replaced.
I will update this review as time progresses.
UPDATE: Its almost to March 27 2023 & its been holding up great. No ripping or tearing stitching holding strong.
Still holds cards really tight, but they are easier to remove.

Worth the money
I have tried other slim wallets but keep coming back to AlpineSwiss. Theirs are much better in construction and in material, and last extremely long. Much better than the cheaper alternatives. Consider paying a bit more but getting your moneys worth with these guys.
