highlight the photometry of 2M0355 (see also Table \[meancolors\]). As demonstrated in Figure \[fig:w1mw2\], with a $W1-W2$ color of 0.59, 2M0355 is 0.24 mag redder than the average of its spectral subtype or 3$\sigma$ from the mean color. Comparing with the 25 similarly classified L$\gamma$ dwarfs, we find that 2M0355 is the reddest known isolated L dwarf in near and mid-infrared colors.

Spectral Features\[spectra\]
----------------------------

2M0355 is classified as an L5$\gamma$ in the optical by @Cruz09 based on its similarity to field L5’s but with very weak FeH absorption and weak Na [I]{} and K [I]{} lines, which are typically interpreted as signatures of low surface gravity. In Figure \[fig:SpeX2\] we show the SpeX prism spectrum for 2M0355 and compare it to the field L5 (presumed age $>$ 1 Gyr) near-infrared standard 2MASSJ08350622+1953050 (2M0835) as well as the $\sim$10 Myr L dwarf 2M1207b (@Chiu06; @Kirkpatrick10; @Patience12). We normalize the spectra separately in each bandpass and smooth 2M1207b by a factor of 3. The shape of 2M0355 in all three bands deviates significantly from the spectrum of the field standard. Compared to 2M1207b, the $H$ and $K$ bands are very similar, but the $J$ band is intriguingly different. 2M0355 has a
