One gram is not the argument
A gram across a pair is below what you can feel. Both gloves sit well under the roughly 40 g threshold where fabric stops registering between palm and rim — see lightest sim racing gloves.
What separates them is how much each brand tells you about the rest of the glove.
Where the SRG1 wins
Published seam position. GCOM states fully external seams, doubled on the short version except on the thumb back. FREEM publishes nothing about its seams — so whether a stitched ridge runs inside the palm is unknown. For a glove you wear for hours, that is the most consequential gap in the SIM21's data.
Published fabrics. AX leather with printed silicone dots on the palm, a 95/5 polyester-spandex knit on the back. A third-party test names "L-Grip" for the palm; no back material is published.
A described cuff. Close-fitting, no hook-and-loop. FREEM does not describe the cuff at all.
Two cuff lengths. Short at €69, long at €59, each with its own size chart.
Where the SIM21 wins
Eight sizes against five. 2XS to 3XL is the widest range in this comparison. The SRG1 stops at XS and XL, so the smallest and largest hands have no option there. See size and fit.
Grip across the whole palm. According to the third-party test, L-Grip covers the entire palm rather than sitting in printed zones. If you move your hands around the rim, there is no grip zone to find.
Touchscreen fingers. Thumb and index, according to the third-party test. GCOM publishes no touchscreen specification.
Price. US$60 against €69, though the gap narrows or reverses depending on the exchange rate and shipping on your order date.
